1. e4 c5 2. Nf3 e6 { Nowadays Polgar varies between this and the Najdorf Variation. } 3. d4 cxd4 4. Nxd4 Nc6 5. Nc3 ( 5. Nxc6 bxc6 6. Bd3 { is a good way to prepare O-O } ) 5... Qc7 6. Be3 a6 7. Qd2 { This is a curious way to develop against the Taimanov Variation. I know Black might like to play ...Nc4, but White's Bf1 would simply trade for it. I suppose the position might transpose to a Scheveningen Variation, but Polgar doesn't usually play that line. In short, I don't see any winning plan emerging for White with Qd2. What is the big threat White might be aiming to make? } ( 7. f4 { intending to meet ...b7-b5 with Nd4xc6 and Bf1-e2-f3 could be successful } ) 7... b5 8. Nxc6 Qxc6 9. f3 Bb7 { Black is not deterred. If Black is to continue developing on the queen-side then this is the best place for the bishop. It "bites on granite", but White's cautious pawn play (Pf3) makes it easier for Black to develop smoothly. } 10. O-O-O Ne7 { From here the knight might maneuver Ne7-c8-b6-c4 or simply support ...d7-d5. Unless White puts more pressure on Black a move such as this can appear completely safe and terrific. White isn't taking away many of Black's options. } 11. Kb1 Ng6 12. h4 b4 ( 12... Bb4 $5 $11 { Fritz7; it might provoke White to play a2-a3, which weakens the king's position } ) 13. Ne2 Ne5 14. Nf4 Rc8 15. Bd4 f6 { It appears Black needs to spend a few moves to ensure the safety of her king before continuing the offense. Can White do much during this time? } ( 15... Nc4 $6 16. Bxc4 Qxc4 { and Black would find it somewhat difficult to develop Bf8 and to keep Ke8 safe } ) 16. Nh5 { This keeps Bf8 tied down. } 16... Qd6 $11 { Fritz7 thinks this is the first moment when Black has equalized! I can only imagine this move is to clear the way for ...Ne5-c6, where the knight would challenge Bd4. } ( 16... Rc7 { over-protecting Pd7 and then ...Ke8-f7 over-protecting Pg7 would free Bf8 to move. } ) 17. Qe1 Qc7 18. Rd2 Bc5 $2 { It's very important to ensure the safety of Ke8 by getting rid of White's more offensively placed pieces. But, why is she gambitting Pg7? I suppose she didn't want to commit her king to the king-side with ...Ke8-f7. Fritz7 just thinks it's a big mistake (+/-) . } ( 18... Nc6 { might be alright, but there's a chance White would sacrifice a piece to attack at f6 or g7 } ) 19. Nxg7+ { Blunder or good move? It's not entirely clear to anyone but Fritz, and "he" often "changes his mind". } ( { The obvious alternative is } 19. Bxc5 Qxc5 20. Nxg7+ { when Black's minor pieces will be well situated for the offense and White's Bf1, in particular, will not be; but it's still a gambit and Black takes a risk. } ) 19... Ke7 20. Qe3 $2 ( 20. Nh5 $4 Bxd4 21. Rxd4 Qxc2+ 22. Ka1 Qc1+ 23. Qxc1 Rxc1# ) ( 20. Bxc5+ Qxc5 21. f4 Nc4 22. Bxc4 Qxc4 23. Qd1 Rhd8 24. Rd4 { when there's no question Ng7 can retreat safely via h5! - Fritz7 } ) 20... h5 $15 { Ng7 is trapped and it will be lost for two pawns; so White will be slightly behind, rather than ahead a pawn. There is also Black's queen-side play still to follow. } 21. Be2 ( 21. f4 $16 { Fritz7 } 21... Ng4 $11 { Already Fritz7 sees it's to Black's advantage! Amazing, isn't it? } 22. Bxc5+ Qxc5 23. Qd3 Rc7 24. e5 { Fritz7 } ) 21... Rh7 22. Nxh5 Rxh5 23. f4 { uncovering an attack on Rh5 and forcing the following move sequence } 23... Bxd4 24. Qxd4 ( 24. Rxd4 $4 Qxc2+ 25. Ka1 Rxh4 $19 { gains a tempo (to save Ne5) by threatening ...Rxh1 Mark and Fritz7 } ) 24... Nc6 { This knight interferes with Black's queen-side offense, so White has more time for his king-side offensive. } 25. Qe3 ( 25. Qxd7+ Qxd7 26. Rxd7+ Kxd7 27. Bxh5 $17 { Fritz7 } ) 25... Rh7 26. g4 Rg8 { White's pawns are the most threatening concerted force on the board, so Black has to play a bit of defense. } ( 26... e5 $17 { I don't think there are many people who would consider this move, even if it's good. } 27. fxe5 Nxe5 28. g5 f5 29. g6 $11 { Fritz7 seems to be teasing us with a dramatic evaluation, but after only a few moves of it's own suggested variation it tosses out a different conclusion. } ) 27. g5 { This, it seems to me, is a bit too soon. Give Polgar time to move her pieces to worse squares before committing to any pawn structure changes. Safer is Be2-f3 or Rd2-d1. } 27... fxg5 28. fxg5 Qe5 { and it's obvious Pe4 is a new weakness in White's position. There is also the immediate threat of ...Rg8xg5. } 29. Rdd1 Kd8 { I like this move a lot. Moving the king to c7 or b8 to defend Bb7 and guard the dark squares is very useful. Black just has to be careful to not walk into trouble. } 30. Qb6+ ( 30. Bxa6 Bxa6 31. Qb6+ Ke7 32. Qxa6 Qxe4 $17 { Fritz7 } ) 30... Kc8 $2 ( 30... Qc7 ) 31. Qf2 $2 ( 31. Bxa6 { gives White a chance! } ) 31... a5 $1 { Her defensive house is in order, so why not spend some moves on offense? This plan, which Fritz7 didn't "see", gives Black an excellent chance to win. } 32. Rhg1 a4 33. g6 ( 33. Rg4 a3 34. bxa3 bxa3 35. Qb6 $17 { Fritz7 } ) 33... a3 34. c3 ( 34. bxa3 bxa3 35. Qb6 Rhg7 36. h5 Qxe4 $17 { Fritz7 } ) 34... Rh6 { Suddenly all the Fritz7 evaluations went big in Black's favor (-+) . } 35. g7 bxc3 { White's posiiton just crumbles and the king-side pawns are no comfort. } ( 35... Rxg7 $4 36. Qf8+ Kc7 37. Qxg7 Qxe4+ 38. Bd3 $13 ) 36. bxa3 ( 36. Qf8+ Kc7 37. Qxa3 ( 37. Qxg8 c2+ { leads to mate because of ...Qe5xb2 } ) 37... Rxg7 $19 { Fritz7; White's pawns will be captured, White's king will be somewhat exposed and Black's extra piece will become a dominant feature of the position } ) 36... Rf6 37. Qb6 Rf7 ( 37... Qxe4+ 38. Bd3 Qxh4 $19 { Fritz7 } ) 38. Rg5 Qxe4+ 39. Bd3 Qf3 ( 39... Qxh4 $19 { Fritz7; is safer because it stays in contact with the back rank at d8. Though the immediate threat to Rg5 is also useful } 40. Rb5 d6 ) 40. Kc2 { Why is White purposefully allowing ...Qf3-f2+, which forces a queen trade? I suppose it doesn't matter because Black isn't interested in a queen trade until she has gobbled up the White king-side pawns. White should try to switch to attacking Kc8 with Rb1 or Rb5. } 40... Rgxg7 ( 40... Qf4 { Fritz7 } ) 41. Rxg7 ( 41. Rb1 Qf2+ ( 41... Nd8 $4 42. Rc5+ $11 ) ( 41... Rxg5 42. Qxb7+ Kd8 43. Qb6+ Ke7 44. hxg5 Qg2+ 45. Kxc3 Qxg5 { is in Black's favor, but White still has a way to try to win, so Grischuk in  the game until Polgar can find a way to end his hopes. } ) 42. Qxf2 ( 42. Kxc3 $2 Qxb6 43. Rxb6 Rxg5 44. hxg5 $19 ) 42... Rxf2+ 43. Kxc3 Rxg5 44. hxg5 Rg2 45. g6 Rg3 $19 ( 45... Ne5 $1 46. Rxb7 Rg3 $19 ) ) 41... Rxg7 42. Rf1 { This is a pretty good attacking scheme. Qb6 holds Kc8 in place and Rf1 threatens the kill (Rf8+) . } 42... Rg2+ ( 42... Qg2+ $4 43. Rf2 ) 43. Kc1 ( 43. Kxc3 Ne7 44. Rxf3 Nd5+ $19 ) 43... Rb2 { Terrific stuff - both are trying every trick in the book to win. } 44. Qxb7+ { White wins a bishop for his efforts, but the simplified queenless ending still looks better for Black; her pawns are together and White's are a mess. } ( 44. Qxb2 $4 cxb2+ $19 { The check gives White no time to capture Qf3. } ) 44... Kxb7 45. Rxf3 Rh2 46. Rf4 d5 47. h5 e5 { ...Nc6-d4, to create the threat of ...Rh2-h1+ or ...e5-e4 to shut out Bd3 might follow. I should add Grischuk really fought well and I expect to see him in the highest ranks sometime soon. } 0-1
