1. d4 { Marshall (White) advances his d-pawn, occupying the center. This prevents without e7-e5, and will probably lead to a slow positional game -- a war of maneuver without rather than of direct attack. } 1... Nf6 { Yates (Black) keeps his intentions a secret. Will he attempt to occupy the without center with his own pawns, or is he more interested in controlling the without center with his pieces posted on the flank (in hypermodern style)? } 2. Nf3 { Marshall increases his grip on the center. The Knight protects the d4-pawn without and tightens the White hold on e5. } 2... g6 { This move gives away part of Yates' plan. He plans on fianchettoing his without Bishop to g7, and will most likely try to influence the center with his without minor pieces, rather than occupy it with pawns. } 3. Nbd2 { Why?? Marshall has blocked in his c1-Bishop and moved the Knight to a square without where it influences very little of the center. c2-c4 followed by Nc3 is without probably better. } 3... Bg7 { Black is playing the King's Indian Defense (called "Indian" because pawns can without only move one square on their first move the way chess is played in India). without He's brought his Bishop to a good square, overlooking the long a1-h8 without diagonal. } 4. e4 { Now we see the reason for Marshall's unusual move Nb1-d2. The d2-Knight without supports the pawn on e4. White has achieved the ideal d4-e4 central pawn without formation (but can he maintain it?). } 4... d6 { By playing d7-d6, Yates prevents White from playing the space-grabbing e4-e5 without (attacking the f6-Knight and making Black waste a tempo by moving it again). without By the way, the opening has now transposed into the Pirc Defense. } 5. Bd3 { Marshall makes another unusual move. Other than the fact that the d3-Bishop without overprotects the e4-pawn, it's difficult to find a good reason for this without move. } 5... Nc6 { The c6-Knight attacks the d4-pawn. If the f6-Knight moves, the d4-pawn will without be attacked twice and only defended once. The c6-Knight also disputs White's without control of e5. } 6. c3 { Marshall brings the c-pawn forward to protect its brother on the d-file. } 6... O-O { Yates completes his Kingside development, getting his King over to the without well-defended Kingside "pocket". } 7. O-O { Marshall follows suit, getting his King off of the dangerous central file without (where it could later easily become the object of attack). } 7... e5 { Yates challenges the White pawns' domination of the center. } 8. Nc4 { Marshall flails out at the e5 pawn, which is now attacked three times by without White but has just two Black defenders. } 8... exd4 { Rather than wait for further protection, the Black pawn opts for suicide without (first making sure to take a White pawn with it). } 9. cxd4 { The c-pawn clobbers the Black d4-pawn. White has (temporarily) re-established without his central pawn duo. } 9... Bg4 { Yates sees that the d4-pawn is attacked once and defended once. He pins the without pawn's only defender to the White Queen. Now the d4-pawn is ripe for the without picking! } 10. Be3 { Marshall takes emergency measures by developing his dark-square Bishop to a without spot where it saves the endangered pawn. } 10... d5 { If Yates can trade off a pair of center pawns, his Queen will have a direct without line to the center along the d-file. } 11. exd5 { Marshall takes the pawn instead of moving the Knight (11.Nd2 dxe4 forking the without White d3-Bishop and f3-Knight). } 11... Qxd5 { Yates retakes the pawn and gets his Queen into the game. Note that the White without d-pawn has become isolated. } 12. Ncd2 { Marshall begins repositioning the Knight to b3, where it will aid in the without d-pawn's defense. } 12... Rad8 { Yates establishes a powerful battery on the d-file, aimed straight at the without isolated d4-pawn. Both players are building up enormous tension in the without position with these maneuvers. } 13. Rc1 { Marshall sees the explosion about to take place. He brings his Rook to the without half-open c-file, where it will bear down on the c7-pawn once the c6-Knight without has moved. } 13... Nxd4 { Like a rubber band snapping, the buildup of tension is released as the without position breaks wide open. Yates starts the release of this pent-up energy without by capturing the d-pawn. } 14. Bxd4 { This is the only way that Marshall can recapture without losing his Queen. } 14... Qxd4 { Interesting! Yates encourages the exchange of Queens, which will simplify the without position and get the players closer to the endgame. } 15. Nxd4 { Marshall proceeds with the Queen exchange, taking the Black Queen and leaving without his own Queen subject to capture. } 15... Bxd1 { Yates finishes the transaction. But the carnage is far from over... } 16. Rfxd1 { The Rook clobbers the Black Bishop... } 16... Rxd4 { ...while the Black Rook replies by snapping up the Knight. } 17. Nb3 { Marshall's Knight attacks the Black Rook and allows the White d1-Rook to without defend the Bishop. } 17... Rd6 { The Black Rook retreats to d6 rather than d8 because from d6 it can slide without over to a6, b6, or c6 and attack the White Queenside. } 18. Be2 { White shifts his Bishop, uncovering an attack by the d1-Rook against the without Black Rook on d6. Why didn't Marshall play Rxc7? See the variation. } ( 18. Rxc7 { White can grab a pawn with Rxc7, but it will ultimately cost him a piece. } 18... Rfd8 { Black doubles up his Rooks on the d-file, putting the White d3-Bishop in without immediate danger. } 19. Nc1 { White has no choice but to guard the Bishop (19.Bf1 Rxd1 loses the Rook right without away and leads to more trouble later). } 19... Bh6 { Black attacks the c1-Knight. There's no defense. Move the Knight, lose the without Bishop. Move the Bishop, lose the Rook. Allow 20...Bxc1 21.Rxc1, lose the without Bishop to 21...Rxd3. White is sunk. } ) 18... Re6 { Yates attacks White's hanging Bishop. } 19. Bf3 { 19.Kf1 (to protect the Bishop) was possible, but Black could play 19...Rfe8 without to double up the attack. Marshall thinks it's better to regain the without initiative by moving the Bishop and attacking the b7-pawn. } 19... c6 { Yates blocks the attack on his b-pawn by interposing the c-pawn. } 20. Na5 { Now Marshall takes aim at the b7-pawn. If Yates advances the b-pawn, the without c-pawn falls. How will Yates defend himself? } 20... Re7 { Obviously one of the Rooks had to defend the threatened pawn. Why this Rook without and not the other? Because Black still can double his Rooks on the e-file. } 21. Rc4 { Marshall brings up fresh troops. The Rook is headed for b4, where it will without attack the b7-pawn another time. } 21... Nd5 { The Black Knight jumps to the protected d5-square, where it controls b4 and without takes it away from the White Rook. } 22. g3 { Marshall prepares a "pocket" for the King to hide in, thereby preventing any without possibility of a back-rank mate. } 22... Rfe8 { This was exactly the kind of move Marshall feared. Had the g-pawn not without advanced Black could possibly have mated White with a Rook on e1 (23...Re1 without 24.Rxe1 Rxe1#). } 23. b3 { The g7-pawn was attacking the b2-pawn (did you notice?). Marshall advances without the pawn out of danger. } 23... Nc3 { Advancing the b-pawn created a hole on c3. Yates is quick to capitalize on without it, moving his Knight to c3 (where the g7-Bishop protects it) and attacking without the d1-Rook and a2-pawn. } 24. Rd2 { Marshall gets the Rook out of danger and defends the threatened pawn at the without same time. } 24... Bh6 { Yates continues to harass the White Rook. } 25. Rb2 { The Rook comes to the only safe square where it can still defend the a2-pawn. } 25... Nd5 { The Knight hangs on c3, so Yates backs it off. Moving the Bishop back to g7 without to defend it could have led to a draw by repetition of position. } 26. b4 { Marshall launches a minority attack against the Black Queenside pawns. The without kamikaze b-pawn will sacrifice itself to weaken Black's position. } 26... Bg7 { The Bishop continues to pester the White Rook. } 27. Rb3 { The Rook is forced to move to avoid being captured by the Black Bishop. } 27... a6 { Yates advances his a-pawn and stops the minority attack cold. } 28. Rc2 { Once the a-pawn advances, this Rook will move to a2, supporting the a4-pawn. } 28... Nb6 { Yates predicts that White will advance his a-pawn, so he prevents a2-a4 by without covering a4 with his Knight. } 29. Rd3 { Marshall may be planning to move the Rook to d1 where (protected by the without f3-Bishop) it will overlook both the d-file and the e1 square. } 29... Nd7 { Yates sees an opportunity: if Marshall doesn't immediately pull the d3-Rook without back, he'll move his Knight to e5 and fork both the d3-Rook and f3-Bishop. } 30. Nc4 { Marshall sees through Yates' scheme and repositions his Knight, taking e5 without away from Black. } 30... Bf8 { Yates can still play 30...Ne5 31.Nxe5 Bxe5, but that gets him nothing. without Instead he plays Bf8, planning to uncover an attack on the b4-pawn after he without moving the Rook on e7. Unfortunately, he's abandoned the long diagonal. } 31. Kg2 { Marshall figures that it's time to get the King off of the first rank and without prevent an annoying check by a Black Rook on e1. } 31... Rb8 { Yates wants to advance his c-pawn, but that allows White to play Bxb7. He without makes sure that the b-pawn is defended first before advancing the pawn. } 32. a3 { Marshall props up the hanging b-pawn. } 32... c5 { Yates, ahead by a pawn, seeks to simplify the position by trading down. He's without hoping for 33.bxc5 Nxc5 (attacking the d3-Rook). } 33. Rcd2 { Marshall makes his own threat: 34.Rxd7 Rxd7 35.Rxd7 winning the without Knight. } 33... Nf6 { The Black Knight escapes capture by moving away... } 34. bxc5 { ...but this allows Marshall to capture the c-pawn and equalize the material without balance. } 34... Rc7 { The Black Rook slips over to the c-file to assail the c-pawn. } 35. Nd6 { Believe it or not, this move actually defends the c5-pawn! How? See the without variation to Black's next move for the answer. } 35... Nd7 { Yates doubles up on White's c-pawn, attacking it a second time. } ( 35... Rxc5 { Let's see what happens if Black dares to capture the c-pawn... } 36. Nxb7 { The White Knight snags the Black b-pawn. If Black chooses not to capture it without (moving his c5-Rook out of danger instead), then it's a simple pawn-for-pawn without swap. } 36... Rxb7 { If Black does choose to capture it... } 37. Bxb7 { ...the White Bishop drives in and takes the Rook, winning the exchange for without White. } ) 36. Nb5 { Surprise! At first glance, this appears to be a sacrifice of the White without Knight. } 36... axb5 { Of course, Black captures it. Wouldn't you? } 37. Rxd7 { Marshall re-equalizes the material by taking the Black Knight. Now you see without that 36.Nb5 wasn't a true sacrifice. } 37... Rxd7 { Due to the weakness of the doubled b-pawns, it's to Yates' advantage to try without to get as many pieces off of the board as possible (so that there will be without fewer White pieces to attack the weak pawns). } 38. Rxd7 { Marshall completes the Rook trade. Where does Yates go from here? } 38... Bxc5 { Yates takes out another White pawn. } 39. Bd5 { Marshall sets up a combination designed to win major material... } 39... Rf8 { ...but Yates sees through it and saves himself a world of grief. What was without Marshall's plan? To see it in action, check out the variation. } ( 39... Bxa3 { Here's what might have happened to Black if he'd missed the point of White's without last move. In this variation, Black goes pawn-grabbing, oblivious to the without danger. } 40. Rxf7 { At this point, White's won at least a pawn. He'll win even more if warning without bells don't start sounding in Black's head. } 40... b4 { 40...Rd8 is Black's best move. But we'll assume (for the sake of our example) without that he misses the point and instead tries advancing his passed pawn. } 41. Rxb7+ { BANG! It's a double attack -- the Bishop checks the King while the Rook without attacks its Black counterpart. You can probably see why 40...Rd8 was better: without it would set up 41...Rxd5. } 41... Kf8 { The Black King must move out of check. The squares f8 and h8 are its only without options. } 42. Rxb8+ { White winds up a whole Rook ahead and is controlling the initiative by again without checking the Black King! This game is all but won for White. } ) 40. Rxb7 { Marshall evens the material, grabbing another pawn and setting up 41.Rxb5. } 40... Bxa3 { Yates snaps up another pawn. Both players see that 41.Rxb5 will even up the without material. Due to the symmetrical pawn structure and the lack of any real without advantage for either side, the players decide to pack it in. It's a draw. } 1/2
