Move 3 e6 (white to move)
FEN: rnbqkbnr/pp1p1ppp/4p3/2p5/4P3/5N2/PPPP1PPP/RNBQKB1R w KQkq - 0 3
Comment: Nowadays Polgar varies between this and the Najdorf Variation.

Move 7 Qd2 (black to move)
FEN: r1b1kbnr/1pqp1ppp/p1n1p3/8/3NP3/2N1B3/PPPQ1PPP/R3KB1R b KQkq - 1 7
Comment: 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?

Move 10 Bb7 (white to move)
FEN: r3kbnr/1b1p1ppp/p1q1p3/1p6/4P3/2N1BP2/PPPQ2PP/R3KB1R w KQkq - 1 10
Comment: 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.

Move 11 Ne7 (white to move)
FEN: r3kb1r/1b1pnppp/p1q1p3/1p6/4P3/2N1BP2/PPPQ2PP/2KR1B1R w kq - 3 11
Comment: 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.

Move 16 f6 (white to move)
FEN: 2r1kb1r/1b1p2pp/p1q1pp2/4n3/1p1BPN1P/5P2/PPPQ2P1/1K1R1B1R w k - 0 16
Comment: 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?

Move 16 Nh5 (black to move)
FEN: 2r1kb1r/1b1p2pp/p1q1pp2/4n2N/1p1BP2P/5P2/PPPQ2P1/1K1R1B1R b k - 1 16
Comment: This keeps Bf8 tied down.

Move 17 Qd6 (white to move)
FEN: 2r1kb1r/1b1p2pp/p2qpp2/4n2N/1p1BP2P/5P2/PPPQ2P1/1K1R1B1R w k - 2 17
Comment: 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.

Move 19 Bc5 (white to move)
FEN: 2r1k2r/1bqp2pp/p3pp2/2b1n2N/1p1BP2P/5P2/PPPR2P1/1K2QB1R w k - 6 19
Comment: 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 (+/-) .

Move 19 Nxg7+ (black to move)
FEN: 2r1k2r/1bqp2Np/p3pp2/2b1n3/1p1BP2P/5P2/PPPR2P1/1K2QB1R b k - 0 19
Comment: Blunder or good move? It's not entirely clear to anyone but Fritz, and "he" often "changes his mind".

Move 21 h5 (white to move)
FEN: 2r4r/1bqpk1N1/p3pp2/2b1n2p/1p1BP2P/4QP2/PPPR2P1/1K3B1R w - - 0 21
Comment: 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.

Move 23 f4 (black to move)
FEN: 2r5/1bqpk3/p3pp2/2b1n2r/1p1BPP1P/4Q3/PPPRB1P1/1K5R b - - 0 23
Comment: uncovering an attack on Rh5 and forcing the following move sequence

Move 25 Nc6 (white to move)
FEN: 2r5/1bqpk3/p1n1pp2/7r/1p1QPP1P/8/PPPRB1P1/1K5R w - - 1 25
Comment: This knight interferes with Black's queen-side offense, so White has more time for his king-side offensive.

Move 27 Rg8 (white to move)
FEN: 6r1/1bqpk2r/p1n1pp2/8/1p2PPPP/4Q3/PPPRB3/1K5R w - - 1 27
Comment: White's pawns are the most threatening concerted force on the board, so Black has to play a bit of defense.

Move 27 g5 (black to move)
FEN: 6r1/1bqpk2r/p1n1pp2/6P1/1p2PP1P/4Q3/PPPRB3/1K5R b - - 0 27
Comment: 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.

Move 29 Qe5 (white to move)
FEN: 6r1/1b1pk2r/p1n1p3/4q1P1/1p2P2P/4Q3/PPPRB3/1K5R w - - 1 29
Comment: and it's obvious Pe4 is a new weakness in White's position. There is also the immediate threat of ...Rg8xg5.

Move 30 Kd8 (white to move)
FEN: 3k2r1/1b1p3r/p1n1p3/4q1P1/1p2P2P/4Q3/PPP1B3/1K1R3R w - - 3 30
Comment: 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.

Move 32 a5 (white to move)
FEN: 2k3r1/1b1p3r/2n1p3/p3q1P1/1p2P2P/8/PPP1BQ2/1K1R3R w - - 0 32
Comment: 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.

Move 35 Rh6 (white to move)
FEN: 2k3r1/1b1p4/2n1p1Pr/4q3/1p2P2P/p1P5/PP2BQ2/1K1R2R1 w - - 1 35
Comment: Suddenly all the Fritz7 evaluations went big in Black's favor (-+) .

Move 36 bxc3 (white to move)
FEN: 2k3r1/1b1p2P1/2n1p2r/4q3/4P2P/p1p5/PP2BQ2/1K1R2R1 w - - 0 36
Comment: White's posiiton just crumbles and the king-side pawns are no comfort.

Move 40 Kc2 (black to move)
FEN: 2k3r1/1b1p1rP1/1Qn1p3/6R1/7P/P1pB1q2/P1K5/3R4 b - - 3 40
Comment: 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.

Move 42 Rf1 (black to move)
FEN: 2k5/1b1p2r1/1Qn1p3/8/7P/P1pB1q2/P1K5/5R2 b - - 1 42
Comment: This is a pretty good attacking scheme. Qb6 holds Kc8 in place and Rf1 threatens the kill (Rf8+) .

Move 44 Rb2 (white to move)
FEN: 2k5/1b1p4/1Qn1p3/8/7P/P1pB1q2/Pr6/2K2R2 w - - 4 44
Comment: Terrific stuff - both are trying every trick in the book to win.

Move 44 Qxb7+ (black to move)
FEN: 2k5/1Q1p4/2n1p3/8/7P/P1pB1q2/Pr6/2K2R2 b - - 0 44
Comment: 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.

Move 48 e5 (white to move)
FEN: 8/1k6/2n5/3pp2P/5R2/P1pB4/P6r/2K5 w - - 0 48
Comment: ...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.
