1.d4 Nf6 2.c4 e6 3.Nc3 d5 4.Bg5 Be7 Queen's Gambit Declined.
5.e3 Nbd7 Turns down the invitation to play the Lasker Defence with 5... Ne4.
6.cxd5 Nxd5 7.Bxe7 Nxe7 7... Qxe7 is probably more accurate.
8.Bd3 e5 8... c5 is more normal here. The light squares may now become vulnerable.
9.Nf3 exd4 10.exd4 10. Nxd4 is better. Now the Isolated Queen's Pawn becomes a liability.
10...Nf6 11.0-0 0-0 12.Ne5 c6 13.Bc4 Ned5 13... Nf5 is the correct move, taking the initiative by attacking the IQP rather than just blocking it.
14.Qf3 Better seems to be 14. Nxd5 cxd5. I don't think recapturing with the knight is good, as it might allow the White bishop some pressure and cedes the initiative.
14...Be6 14... Nb6! gets the bishop for knight.
15.Rad1 Qc7 16.Rfe1 Rad8 17.Rc1 Qb6 !
18.Red1 Qa5 ! Not 18... Qxb2? 19. Rb1 Qa3 20. Rxb7.
19.Bb3 Qb4 20.Ne2 Nc7 ! Relieving the pressure on the light squares with exchanges, and exposing the IQP. "I managed to force an easy target in the opening by creating an isolated d4 pawn. Then I captured it after a boring manoeuvring game." Ben Lim.
21.Nd3 Qe7 22.Ne5 Bd5 23.Bxd5 Ncxd5 ?! Wrong knight. This one should be headed to e6 to put pressure on d4.
24.h3 Nd7 25.Nd3 Rfe8 26.Ng3 g6 ?! Not necessary, as 26... Qh4 puts pressure on d4 and keeps the initiative.
27.a3 ?! 27. Re1 grabs the initiative.
27...h5 28.Re1 Qf6 29.Qxf6 N7xf6 30.Nc5 Rxe1+ 31.Rxe1 b6 32.Nd3 Kf8 After the exchanges the IQP looks very vulnerable.
33.Kf1 Ne7 ! Oh dear. This exposes the IQP.
34.Ne2 c5 !
35.Rc1 ? Pointless, as the pawn is still pinned to the knight on d3. Now more pressure is heaped on d4.
36.b4 cxb4 Or 36... Nxd4 and force a pair of knights off as well as grabbing the pawn.
37.Nxb4 Nxd4 38.Nxd4 Rxd4 39.Rc8+ Kg7 40.Ke2 Rd7 41.Nd3 Nd5 "My opponent resigned too early." Ben Lim. Quite hopeless. Maybe 42. g4 h4 43. g5 Re7+ 44. Kf3 Nc7 45. Kg4 Nb5. Another plan is ... Rc7 forcing the Rooks off, otherwise ... Nc3 and ... Nb5 again hitting the a3 pawn. I can't see how White can stop this. 0-1
