1. e4 { At this time (1924), the most popular opening move for White. It grabs space without in the center and gives the Queen and light-square Bishop an outlet for without development. } 1... e5 { If the King's pawn push is a good opening move for White, it's equally good without for Black, and for the same reasons. } 2. f4 { This is the King's Gambit, an opening that was extremely popular in the 19th without Century. In this opening, White offers to gambit a pawn to lure Black's without e-pawn onto a flank file (the f-file), thus weakening Black's center. } 2... exf4 { Bogo accepts the gambit pawn. Now he's a pawn ahead, but his center is weak, without and the advanced f4-pawn may become hard to defend. } 3. Be2 { Tartakower plays an unusual move here. 3.Bc4 is normal, but White doesn't without like the looks of 3...d5.  3.Bd3 is bad because it blocks White's d-pawn. So without White prefers to develop the Bishop here. } 3... d5 { Bogo offers to return the gambit pawn. If White plays 4.exd5, Black can play without ...Nf6 without having to worry about the possible reply e4-e5. } 4. exd5 { Tartakower accepts the pawn offer. Now Bogo can play 4...Qxd5 and stay a pawn without ahead, but White's reply 5.Nc3 (threatening the Queen) would make Black without waste a tempo retreating the Queen. So... } 4... Nf6 { ...Bogo develops his Knight (now that it's safe to do so, since White no without longer has a pawn on the e-file) and attacks the d5-pawn as without well. } 5. c4 { Tartakower props up his pawn. This has the added benefit of giving his Queen without some scope along the a4-d1 diagonal. } 5... c6 { Black hits the pawn a second time, threatening to grab the c4-pawn as well without (6...cxd5 7.cxd5 Nxd5). } 6. d4 { Tartakower anticipates an exchange of pawns in the center. By advancing his without d-pawn, he insures that he'll have at least one pawn in the center, without controlling space on Black's half of the board. } 6... cxd5 { Bogo begins an exchange in which he expects to post his Knight on the without important center square d5, after 7.cxd5 (i.e. 7.cxd5 Nxd5). } 7. Bxf4 { Tartakower takes the other pawn instead. This makes the material even and without gives White an edge in development (White has more pieces and pawns off of without their starting squares than Black does). } 7... dxc4 { Bogo forges ahead and grabs White's c-pawn before White has a chance to play without c4-c5. If Black had allowed the White c-pawn to advance, it would have given without White a 3-2 pawn majority on the Queenside. } 8. Bxc4 { The White Bishop recaptures and makes the material even. White has a big lead without in development, but the downside is that his King is awfully exposed. The without King's Gambit often leads to double-edged positions like this. } 8... Bb4+ { Black has to develop this Bishop sooner or later, so why not develop it with without a check? } 9. Nc3 { The White Knight develops off of the back rank and blocks the check. } 9... O-O { Bogo gets his exposed King out of the drafty center. Now his Rook can take without over the open e-file. } 10. Ne2 { Tartakower gets his other Knight out with three purposes: to block the without threatened Rook check at e8, to protect the c3-Knight (in the event of without ...Bxc3+), and to clear the way for castling. } 10... Bg4 { Bogo ties Tartakower up in knots. This developing Bishop move pins the without e2-Knight to the White Queen. } 11. O-O { The King gets out of the center, which ends the pin by the b4-Bishop. Notice without how White's Rook on f1 commands the half-open f-file. } 11... Nbd7 { Bogo develops his last minor piece. He looks ahead to a future Nd7-b6, without attacking White's Bishop on c4. } 12. Qb3 { Tartakower gets his Queen out of the danger zone (away from the threatening without g4-Bishop) and attacks the other Black Bishop on b4. } 12... Bxc3 { Black takes the Knight and leaves White an interesting problem: recapture without with the Queen or Knight (which leaves the d-pawn isolated) or recapture without with the b-pawn (isolating the a-pawn and giving White three pawn islands)? } 13. bxc3 { Tartakower recaptures with the b-pawn. Now his d-pawn is supported by another without pawn, and his Queen attacks the Black pawn on b7. But White now has three without pawn islands and his a-pawn is isolated and may become a target without later. } 13... Nb6 { The Knight blocks the White Queen's attack and menaces the White Bishop on without c4. } 14. Bd3 { White has the advantage of having both of his Bishops, an advantage that he without wants to keep. So the light-squared Bishop backs off. } 14... Nfd5 { Black's aggressive Knights continue to threaten White's Bishops! Also, see without what a good center square the Knight occupies. From d5, it influences eight without squares (the best a Knight can do!). } 15. Bd2 { Again, Tartakower wants to hold on to the advantage of having both of his without Bishops (to see why, refer to the Glossary entry entitled "Two Bishops/Two without Knights"). So White retreats the dark-squared Bishop. } 15... Bxe2 { Bogo gives up his other Bishop to kill off White's only Knight. What Black without has achieved is the weakening of White's c3-pawn (since White's Knight was without defending it). Now that the Knight is gone, the c3-pawn will become a without target. } 16. Bxe2 { The Black Bishop comes off the board and goes back into the box. Now White without has two Bishops against two Knights, a big advantage on an open board. How without should Black proceed? } 16... Rc8 { Bogo attempts to tie up White's Queenside forces by attacking the weakened without c3-pawn. Since the pawn is now attacked twice (by Black's d5-Knight and without Rook), White's Queen and d2-Bishop are tied to its without defense. } 17. Rf3 { The Rook advances and defends the pawn. White could also have defended the without pawn by advancing it to c4, but this move carries a whole new set of without problems with it (see the variation). } ( 17. c4 { Let's examine the idea of defending the c-pawn by advancing it. (Variation by without Alekhine) } 17... Nf6 { Of course, Black must retreat the threatened Knight. This uncovers an attack without by the Black Queen against the White d4-pawn. } 18. d5 { White defends this pawn by advancing it also. } 18... Ne4 { The Black Knight dives in and attacks the d2-Bishop. } 19. Bb4 { The threatened Bishop has to move, so it goes to a square where it attacks without Black's f8-Rook. } 19... Re8 { The Rook goes to an open file where it will attack the e2-Bishop (after the without e4-Knight moves). White is back in the same boat as before, with the c4-pawn without attacked twice and defended twice, and now Black has other threats as without well! } ) 17... Qc7 { The Black pieces continue to pile up on White's c-pawn. Now the Black Queen without gets into the act. } 18. Raf1 { Tartakower comes up with his own threat. He doubles his Rooks on the f-file, without creating a battery that puts pressure on Black's f7-pawn. } 18... f6 { Why does Bogo advance the pawn and create a pin on his own d5-Knight (from without the White Queen)? He plans to move his own Queen and doesn't think too much without of White's Queen and both Rooks bearing down on f7. } 19. Bd3 { How can the Bishop move here and block the f3-Rook's defense of the c3-pawn? without Because the d5-Knight is pinned and can't attack the pawn! The well-placed without Bishop on d3 controls two diagonals (a6-f1 and b1-h7) as without well. } 19... Nc4 { In spite of the fact that Knights are usually inferior to Bishops on an open without board, Bogo is making the most of what he has. If the Knight is allowed to without capture the e2-Bishop, it will then fork White's Queen and both without Rooks! } 20. Rh3 { Surprise! Tartakower hits Black with an ugly threat that must be immediately without dealt with, giving Black no time to capture the e2-Bishop and fork all three without of White's heavy pieces! (See the variation to Black's next without move). } 20... g6 { Bogo advances this pawn to block the White d3-Bishop's attack on the h7-pawn. without But now Black's Kingside pawns are very weak (especially the one on f6). } ( 20... Nxd2 { Here's why Bogo can't take the d2-Bishop...it leads to a forced without mate! } 21. Bxh7+ { The White Bishop grabs the pawn with impunity (the King can't capture the without Bishop, which is protected by the h3-Rook!) } 21... Kf7 { Obviously the King must flee, and f7 is the only square. } 22. Qxd5+ { The Queen grabs the Knight and checks again! } 22... Ke8 { Moving the King is again the only escape (and it doesn't matter if the King without goes to e7 or e8, as we'll soon see). } 23. Re1+ { White checks yet again! } 23... Qe5 { Black is forced to block check with the Queen, because the King can't move without and blocking with the Knight just loses both the Knight and Queen. } 24. Rxe5+ { Even if this variation wasn't a forced mate, White's material advantage is without now so overwhelming that he should win anyway. } 24... fxe5 { Absolutely the only move for Black. } 25. Qe6+ { Another check! The walls are closing in on the Black King! } 25... Kd8 { Again, Black has just a single move to get out of check. } 26. Qd6+ { The Queen checks again, driving Black's King to the fatal square. } 26... Ke8 { I guarantee you that the King won't move again! } 27. Bg6+ { Another check! Black has only a single move to block check! } 27... Rf7 { The only move Black has. But now it's curtains for him. Do you see the without winning move? } 28. Rh8# { And that's all she wrote for Black! } ) 21. Re1 { Rooks belong on open (or half-open) files. Tartakower siezes control of the without e-file. } 21... Nxd2 { Bogo takes away some of White's advantage by capturing one of White's strong without Bishops. Now that White's dark-square Bishop is gone, this makes White without slightly weaker on the dark squares. } 22. Qxd5+ { Tartakower keeps the material even by capturing the Black Knight with without check. } 22... Qf7 { Bogo blocks the check and offers to exchange Queens... } 23. Qxf7+ { ...an offer which Tartakower accepts. } 23... Rxf7 { Bogo completes the exchange of Queens. But now his Knight is alone, without undefended deep inside enemy territory! } 24. Re2 { Of course, Tartakower attacks Black's main weakness (his Knight), driving it without back. } 24... Nc4 { The Knight retreats to the safe haven of the c4-square, where it's protected without by the Rook on c8. } 25. Re8+ { The crowd is stunned! Many spectators gasp audibly, and many more exchange without silent surprised glances, as if to say "Doesn't this lose the White Rook?!". } 25... Rxe8 { Bogo, seeing more than we do, heaves a great sorrowful sigh and captures the without Rook. } 26. Bxc4 { Tartakower grabs the Knight and pins the f7-Rook! He used a tactic called without "deflection" to lure the Rook off of the c-file, so that he could take the without Knight and pin (and win!) the f7-Rook. He deflected the Black Rook away from without the protection of the c4-Knight, allowing the Bishop to capture it and pin without the f7-Rook. } 26... h5 { Bogo is in no hurry to move his King (since the f7-Rook is lost whether the without Black King moves now or later). Instead, he advances his h-pawn, to take without space away from White's h3-Rook. } 27. Kf2 { The White King advances to prevent the e8-Rook from invading the White without position by moving to e2. In your games, look for moves like this that take without squares away from your opponent. } 27... Rc8 { The Rook attacks White's Bishop. Bogo is trying to prod Tartakower into without resolving the pinned-Rook situation. } 28. Bxf7+ { Tartakower obliges by removing the Rook from the board. } 28... Kxf7 { Of course, Bogo had to recapture or be behind by a piece. Look at the board. without The material is dead even. Black has a 3-2 Kingside pawn majority while without White enjoys a 3-2 advantage on the Queenside. } 29. Re3 { The Rook siezes the open e-file, cuts down the Black King's mobility, and without continues to defend the threatened c3-pawn. } 29... b5 { The Black b-pawn grabs space and prevents White's a-pawn from advancing to without a4. } 30. Ke2 { From looking at where each side's pawn majority is, we know that White should without attack on the Queenside. The White King heads for the Queenside, to help without support the attack. } 30... Rc6 { Bogo would seem to be contemplating his chances of getting a draw after without exchanging Rooks (31...Re6 32.Rxe6 Kxe6). } 31. Kd3 { The White King comes to d3 to protect the c3-pawn. This frees up White's without Rook, letting it perform other useful tasks. } 31... h4 { Black's pawns continue to storm the Kingside. Bogo intends to play ...g6-g5, without forming a pawn chain and allowing his King to penetrate White's Kingside via without the light squares (if neccessary). } 32. Re2 { Tartakower's Rook, now free to maneuver, pulls back to the second rank, where without  it can move quickly to either the Kingside or Queenside as needed. } 32... g5 { Bogo completes the pawn-chain. Now, if he advances the King to g6 (protecting without f5), he could push the f-pawn to f5 and continue the pawn without assault. } 33. Rb2 { Since there's no immediate threat from Black on the Kingside, Tartakower without makes his own threatening move, menacing the b5-pawn. } 33... Rb6 { Protecting the pawn by a7-a6 cuts the Black Rook off from the a-file. Bogo without prefers to keep lines open for his Rook, so he defends the b-pawn with his without Rook. } 34. d5 { Tartakower advances his passed-pawn, intending to support it by advancing his without  King. } 34... Ke7 { The Black King shifts toward the d-file, intending to head off and blockade without the White d-pawn. } 35. Kd4 { The White King moves ahead to support the advanced passed d-pawn. } 35... g4 { Now that he seems to have neutralized White's passed-pawn advance, Black without continues his Kingside pawnstorm. } 36. Kc5 { White has a three-part plan in mind: 1) to win the Black b-pawn by exchanging without Rooks on b5; 2) to advance his own c-pawn to c4 to protect the d-pawn; 3) to without capture the Black a-pawn with his King. } 36... Rb8 { Black has his own threat in mind: to move his Rook to c8 where it will check without the White King. After the White King moves away, the Rook will capture the without White pawn on c3. } 37. Kd4 { White has to abandon his original plan and come up with a new one: advance without the c-pawn to c4, as the Black b-pawn can't recapture due to Rxb8. Then without White will push the pawn to c5, and have two dangerous connected passed without pawns. } 37... Rb6 { Bogo pushes the Rook back, nipping Tartakower's plan in the bud. Now if White without pushes with 38.c3-c4, Black's b-pawn can capture, as the Black Rook is now without protected by the a7-pawn. } 38. h3 { Tartakower has to come up with his third plan in three moves! Now he plans to without trade off a pair of pawns to defuse the potentially dangerous Kingside without pawnstorm. } 38... g3 { Now both sides' g- and h-pawns are locked, but Black has an ace in the hole: without his f-pawn! It can still advance and break the blockage, which will give without Black a passed pawn on either the f- or g-files. } 39. a3 { Tartakower prepares to play Rb2-b4. After the White King moves, the Rook on without b4 will menace the Black h-pawn. } 39... Kd7 { Bogo gets his King in front of White's passed pawn. } 40. Kc5 { Tartakower is considering advancing the d-pawn to d6 to cut down the Black without Rook's mobility. Also, with the King off of the 4th rank, White can play without Rb2-b4 and threaten the Black h-pawn. } 40... Rb8 { The Black Rook backs off to a square from which it can easily shift to the without Kingside, if necessary. } 41. Rb4 { Trading Rooks (starting with 41.Rxb5) is bad for White (see variation), so without Tartakower decides to threaten the Black h-pawn. } ( 41. Rxb5 { Here's why White's game collapses if he trades Rooks. White begins by taking without the Black b-pawn. (Variation by Alekhine). } 41... Rxb5+ { Black, of course, responds by capturing the Rook. } 42. Kxb5 { The White King must recapture, or White will be behind by a Rook. } 42... f5 { The Black f-pawn advances, trying to promote to a Queen. } 43. Kc4 { The chase is on! The White King tries to catch Black's f-pawn. } 43... f4 { The pawn keeps pushing for the finish line. } 44. Kd3 { The King tries to head off the pawn. Who will win the race?!? } 44... f3 { Black wins! If the g2-pawn takes the Black f3-pawn, then the g3-pawn will without advance and promote. If, instead, the White King moves to e3, then the Black without f3-pawn captures the g2-pawn and still can't be stopped by the without King! } ) 41... f5 { Black is not afraid of losing his h-pawn, because he can still keep the without material even (see the variation to White's next move). } 42. a4 { Now White plans to win Black's b-pawn. White will capture it with the a-pawn, without then advance his c-pawn to defend both the b5 and d5-pawns. } ( 42. Rxh4 { In this variation, we'll see what happens if White captures Black's h-pawn. } 42... Rc8+ { Black checks, with a skewer (or x-ray attack) on the White without c3-pawn. } 43. Kxb5 { The White King gobbles up the Black pawn. Now White is two pawns ahead (but without this is only temporary, as we'll see). } 43... Rxc3 { Black's Rook grabs a pawn. Black is still down a pawn, but the Black Rook's without control of the c-file keeps the White King from coming to the rescue of the without d5-pawn. Black will soon win it (or the g2-pawn) and even up the without material. } ) 42... a6 { Bogo defends the b-pawn with the a-pawn. } 43. Kd4 { The White King gets out of the way of the c-pawn, so that it can advance and without hit the b-pawn again. } 43... Re8 { Believe it or not, this move actually prevents White from capturing the without b-pawn! To see why, check out the variation to White's next move. } 44. Kd3 { The King backs up to allow the White Rook access to the Kingside. } ( 44. axb5 { Here we'll look at what happens if White immediately captures the b-pawn. without This variation was worked out by Alekhine after the round ended. } 44... Re4+ { Instead of recapturing immediately (which leads to the loss of a pawn), Black without checks the White King. } 45. Kd3 { The King moves out of check. } 45... Rxb4 { Black decides to swap off the Rooks. } 46. cxb4 { Of course, White must recapture, or be behind by a Rook! } 46... axb5 { After this recapture, Black should be able to win the d-pawn (due to the laws without  of opposition) and then go on to win with his extra pawn. } ) 44... bxa4 { Bogo swaps off a pawn! This sacrifice will allow his Rook to invade White's without position (as we'll soon see). } 45. Rxa4 { Of course, White takes the pawn! } 45... Re1 { Bogo charges in with his Rook. He hopes that White will take the a-pawn, without displacing the White Rook and allowing the Black Rook to grab the White without Kingside pawns. } 46. Rxa6 { White accepts the sacrificed pawn. } 46... Rg1 { The Black Rook threatens the White g2-pawn. But it seems that Bogo has without miscalculated... } 47. Ra2 { ...because the defense of the pawn is simple for White to acheive! Now White without has two connected passed pawns (on the c & d files)! } 47... Kd6 { Bogo makes the only really constructive move: the Black King threatens the without White d-pawn. } 48. c4 { The c4-pawn protects its brother on the d-file. Now the White position has no without real weaknesses for Black to exploit. } 48... Ke5 { If the King advances to f4, the d-pawn advances unstoppably to promote to a without Queen. So what is Bogo doing? He's marking time, awaiting further without developments and praying for a draw by threefold repetition of position. } 49. Re2+ { White checks with his Rook and drives the Black King back. } 49... Kd6 { The only move Black has that doesn't immediately lose the game. } 50. Rc2 { Now the Rook slips back to the Queenside to support the advance of the White without c-pawn. As a general rule, support the advance of your passed pawns by without putting your Rooks behind them on the same file. } 50... Kc5 { The Black King stops the c-pawn's advance and still denies the d6-square to without White's d-pawn. } 51. Rd2 { As the White King can't move ahead and support the d-pawn's advance (since without Black controls both d4 and e4), the White Rook shifts over to guard the without d-pawn (once the White King goes to c3 to guard the c-pawn). } 51... Rf1 { The Black Rook guards the advance of the f-pawn. Bogo hopes to create a without passed pawn on the f- or g-file. But notice how Black's Rook blocks the without advance of the f-pawn. That's why Rooks belong behind passed pawns, not in without front of them. } 52. Ke2 { A move with a dual purpose: the King attacks Black's Rook while the White without Rook now supports the d5-pawn's advance. } 52... Rg1 { The Rook comes back to g1 to threaten the g2-pawn again, forcing White's King without to move (so that the White Rook can defend the g2-pawn). } 53. Ke3 { The White King doesn't have to protect the c4-pawn, because if the Black King without captures the pawn, the d-pawn heads for d8 and promotion, outrunning the without Black King. } 53... Kd6 { Due to the lack of any really constructive moves in this position, Bogo marks without time by shifting his King. } 54. c5+ { The pawn checks with impunity! If the Black King captures it, the d-pawn will without advance to become a new Queen, protected by the White Rook. } 54... Kxc5 { Bogo takes the pawn anyway! He counts on being able to get his Rook to his without first rank (White's eighth rank) in time to stop the d-pawn. } 55. d6 { Predictably, the pawn advances toward the promotion square. } 55... Re1+ { Rather than trying to get his Rook back by ...Ra1 (which cuts things pretty without close), Bogo checks instead. This makes White waste a tempo getting his King without out of check, and will give the Black Rook access to e8. } 56. Kf4 { The White King is forced to the f-file. If it had moved to the d-file, it without would have blocked the d6-pawn's protection from the White Rook, allowing without the Black King to take the pawn. } 56... Re8 { The Black Rook gets back in plenty of time to block the d-pawn's promotion. } 57. d7 { The pawn steps ahead again, attacking the Rook and threatening promotion by without d7xe8 as well. } 57... Rd8 { Of course, the Rook blockades White's dangerous passed pawn. But now look at without the position of the White King. It sits among the Black pawns like a wolf without among a flock of sheep! } 58. Kxf5 { Black is finished. The White King will gobble up the immobile Black Pawns, without giving White two connected passed pawns. The Black Rook can't move and the without Black King can't cross the d-file! The pawns can't be defended! Bogo without resigns. } 1-0
