Move 2 c5 (white to move)
FEN: rnbqkbnr/pp1ppppp/8/2p5/4P3/8/PPPP1PPP/RNBQKBNR w KQkq - 0 2
Comment: Timman has played many openings.

Move 5 e6 (white to move)
FEN: r1bqkbnr/pp1p1ppp/2n1p3/8/3NP3/8/PPP2PPP/RNBQKB1R w KQkq - 0 5
Comment: This is one of the variations Polgar plays, so it appears Timman has decided she might not like to face it from the other side. Unlike variations with ...d7-d6 where Black uses an early ...Ng8-f6 to (more-or-less) force White into Nb1-c3 before c2-c4, in this variation the threat of an early ...Bf8-b4 helps to serve the same purpose. The thorny light square pawn structure also inhibits Bf1-c4. So, White usually aims for a Classical set-up with Nb1-c3, Bf1-e2, O-O and possibly Bc1-e3. This is one good way to get a "normal" Scheveningen position without facing the Sozin (Bf1-c4) , Velimirovic (Bf1-c4, Bc1-e3, Qd1-e2, O-O-O) or Keres Attack (an early g2-g4) . The primary cost to avoiding early king-side development (or any preparation to remove Ke8 from the center) is that White has some attacking options.

Move 6 a6 (white to move)
FEN: r1bqkbnr/1p1p1ppp/p1n1p3/8/3NP3/2N5/PPP2PPP/R1BQKB1R w KQkq - 0 6
Comment: preventing Nb5 and possibly preparing ...b7-b5 and ...Bc8-b7; strangely Fritz7 doesn't like this move and says 6. Be3 gives White a nice advantage.

Move 9 Bb4 (white to move)
FEN: r1b1k2r/1pqp1ppp/p1n1pn2/8/1b1NP3/2N1B3/PPP1BPPP/R2Q1RK1 w kq - 6 9
Comment: This is a variation which was conceived in the 1960s, was revived in the 1980s by Karpov (and others) and has become popular again in the 2000s. White can defend Pe4 or attempt to play on the dark squares where Black is a little weak (only pieces guarding b6 & d6) .

Move 9 Na4 (black to move)
FEN: r1b1k2r/1pqp1ppp/p1n1pn2/8/Nb1NP3/4B3/PPP1BPPP/R2Q1RK1 b kq - 7 9
Comment: Offering Pe4 and taking aim at b6; naturally Nd4 will need to exchange with c6 to allow Be3 to support Na4-b6.

Move 11 bxc6 (white to move)
FEN: r1b1k2r/2qpbppp/p1p1pn2/8/N3P3/4B3/PPP1BPPP/R2Q1RK1 w kq - 0 11
Comment: Fritz7 seems to like ...dxc6, but I have to admit I've never seen that move.

Move 13 Qxc8 (white to move)
FEN: 1rq1k2r/3pbppp/p1p1pn2/8/4P3/4B3/PPP1BPPP/R2Q1RK1 w k - 0 13
Comment: White's Pb2 & Pe4 are threatened. Having a queen or bishop at c3, d4 or e5 would serve to restrain Black.

Move 14 d5 (white to move)
FEN: 1rq1k2r/4bppp/p1p1pn2/3p4/3BP3/8/PPP1BPPP/R2Q1RK1 w k - 0 14
Comment: Black takes the moment to gain some space in the center. Though it could be argued this just makes it easier for White to force lines open for the two bishops and White's other heavy pieces I think most players would follow Timman's lead.

Move 15 cxd5 (white to move)
FEN: 1rq1k2r/4bppp/p3pn2/3p4/3B4/8/PPP1BPPP/R2Q1RK1 w k - 0 15
Comment: This, incidentally, has the effect of making Bd4 rather safe, at least for the moment Black has no pawns to challenge it.

Move 17 Rxc4 (black to move)
FEN: 1rq2rk1/4bppp/p3pn2/8/2RB4/8/PP2BPPP/3Q1RK1 b - - 0 17
Comment: A Classical evaluation has to note that White has the two-to-one queen-side pawn majority when Black doesn't have a compensating central pawn presence and White has the two bishops. These are slight, but enduring positional advantages. I look at these two elements in terms of whether they help White to win: the bishops are considered a slight material advantage and the pawn majority is considered useful because their distance from the kings means that they can more easily be advanced (particularly in an ending) to create a passer which could promote.

Move 18 Qc2 (black to move)
FEN: 1r3rk1/1q2bppp/p3pn2/8/2RB4/8/PPQ1BPPP/5RK1 b - - 2 18
Comment: threatening Rc4-c7

Move 19 b3 (black to move)
FEN: 1r3rk1/1q2bppp/p3p3/3n4/2RB4/1P6/P1Q1BPPP/5RK1 b - - 0 19
Comment: Be2-f3 is appealing, but Nd5 can be supported by pieces. So, she keeps Be2 aligned with Pa6. I think 19. b3 is to defend the pawn AND to allow Bd4 to retreat to a1, so White can consider an offensive on the king-side.

Move 20 Qb2 (black to move)
FEN: 1r1r2k1/1q2bppp/p3p3/3n4/2RB4/1P6/PQ2BPPP/5RK1 b - - 2 20
Comment: according to Fritz7; not only threatening Bxg7, but controlling a3 to prepare Rf1-c1

Move 22 Na4 (white to move)
FEN: 1r1r2k1/1q2bppp/p3p3/8/n2B4/1P6/PQR1BPPP/5RK1 w - - 5 22
Comment: He shouldn't put this piece out on a limb until he's gotten Pg7 defended. Of course, Fritz7 disagrees.

Move 23 Qe4 (white to move)
FEN: 1r1r2k1/4bppp/p3p3/8/n2Bq3/1P6/P1R1BPPP/Q4RK1 w - - 7 23
Comment: This is the tactic Black expects will hold things together for him.

Move 24 Bc5 (white to move)
FEN: 1r1r2k1/5ppp/p3p3/2b5/n2Bq3/1P6/P2RBPPP/Q4RK1 w - - 9 24
Comment: The problem with moves such as this is they force a dissipation of the immediate pressure and result in an even simpler position where White's bishop's superiority becomes more clear.

Move 25 Qc3 (black to move)
FEN: 1r1r2k1/5ppp/p3p3/2n5/4q3/1PQ5/P2RBPPP/5RK1 b - - 1 25
Comment: White is still avoiding Be2-f3 because it just doesn't belong there. Instead they fight over the d-file and central squares; Timman can be quite Classicly inclined at times.

Move 27 g6 (white to move)
FEN: 1r4k1/5p1p/p3p1p1/2n5/4q3/1P6/P2QBPPP/5RK1 w - - 0 27
Comment: The tactics have died down and White continues the original plan of development while keeping an eye on Pa6. Black's lone achievement is to simplify a bit so that Kg8 will be relatively safe.

Move 27 Rc1 (black to move)
FEN: 1r4k1/5p1p/p3p1p1/2n5/4q3/1P6/P2QBPPP/2R3K1 b - - 1 27
Comment: Amazingly, after this Black has a lot of problems. Nc5 is strangely immobile and nearly defenseless. It's situations like this which seem so unexplainable and which computer programs exploit regularly.

Move 31 Qe4 (white to move)
FEN: 2r3k1/5p1p/p2Qp1p1/2n5/1P2qP2/8/P3B1PP/2R3K1 w - - 1 31
Comment: Polgar nails down the position and lets Pb4 win a piece; neat!
