Two Old Games

ALD-RMD [D55]

1.d4 Nf6 2.c4 d5 3.Nc3 e6 4.Bg5 Be7 5.Nf3 O-O 6.e3 = Nc6 {My wife often plays this in this kind of position. I personally don't like it because it closes off the possibility of playing ...c5.} 7.Bd3 h6 8.Bxf6 {Better is 8.Bh4 since this bishop should not be traded off in the QGD.} Bxf6 9.cxd5 {Like my eighth move, this is a move which could have been ruled out on general principles without calculation. In the QGD White does not play cxd5; better is 9.O-O.} exd5 = 10.Qc2 {10.O-O -0.15 CAP} Nb4 11.Qd2 {11.Bh7+!? Kh8 12.Qb3 Nxa2 13.Qxa2 Kxh7 14.Nxd5 Bg4 -0.10d14 Tiger 2004} Bg4 12.Be2 Bf5 13.O-O Qd6 {13...Qd7} 14.Nb5 Qe7 15.Nxc7 Rac8 {15...Qxc7 16.Qxb4} 16.Nb5? {16.Rfc1 hangs on to the extra pawn.} Rc2 17.Qd1 Rxb2 {17...Rxe2 18.Qxe2 Bd3 19.Qd2 Bxb5} 18.a3 Nc6 {Too passive; 18...Nc2!?} 19.Bd3? {It wasn't immediately obvious to me, but this loses a piece. My wife saw it almost instantly; 19.Nc3} Bxd3 20.Qxd3 Qe4 21.Qxe4 dxe4 22.Ne5 {22.Rfb1 Rxb1+23.Rxb1 exf3 24.gxf3} Rxb5 23.Nxc6 {Why trade another piece when I'm already down? This made no sense; 23.a4} bxc6 24.Rfc1 Rb6 {24...c5!} 25.a4 a5 26.Rc5 Ra627.Rac1 Rc8 {27...Rb8! defends the pawn indirectly.} 28.g3 Be7 29.Re5 Ba3 30.Rc3 Bb4 31.Rc4 Kf8 32.Rxe4 Ra7 33.Kg2 Re7 34.Rxe7 Kxe7 35.d5 {Premature; 35.Kf3} Kd6 36.dxc6 Rxc6 37.Rf4 f6 38.Rg4 g5 39.Rd4+ Kc5 40.h3 Rd6 0-1 {Maybe I resigned just a bit too soon, but Black's win is a matter of simple technique. 41.Re4 Rd2 42.Re7 Ra2 43.Rf7 Bc3 44.h4 Kb4 45.h5 Kxa4 -4.22/d14 Tiger 2004}

RMD-ALD [C68]

1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Bc4 Nf6 = 5.Nc3 {5.O-O} Bc5 6.d3 O-O 7.O-O d6 8.h3 {8.Bg5; 8.Nd5=} b5 9.Bb3 {-0.52 CAP} Bb7 {9...Na5 is probably best here; 9...h6 is the most commonly played move.} 10.Ng5 Qd7 11.Nd5 Nxd5 12.Bxd5 h6 13.Nxf7?! {My wife loves to make this exchange whenever she has the opportunity, but seldom manages to achieve an advantage with it.} Rxf7 14.Bxf7+ Qxf7 15.Qg4 {15.Be3} Rf8! {Correctly calculating that there is nothing to fear from 16.Bxh6.} 16.Bxh6 Kh7? {A complete waste of time. Better to continue my own plans with 16....Bc8.} 17.Bg5 {17.Be3 is still best.} Qg6 {17...Bxf2+} 18.Kh2 Rxf2? {This exposes Black to an extremely deep winning combination by White, which fortunately for me my wife did not find. That is hardly surprising since even in analysis, it took me a very long time to work through all the complications.} 19.Qh4+ {19.Rxf2! Bxf2 20.Rf1! Qf7 (if the bishop retreats, then 21.Rf8 wins instantly for White) 21.Kh1! (to get the White King out of reach of the dark-squared bishop) Nd4 after which Black has no saving move, for example 22.Bh4 Qe6 23.Qh5+ Qh6 24.Qxh6+ gxh6 25.Bxf2 +-} Kg8 20.Rxf2 Bxf2 21.Qxf2 Qxg5 22.Rf1 Qe7 23.h4 Nd4 24.h5 Ne6 25.Qa7 {An odd move, taking the White queen away from the main action.} Qh4+ 26.Kg1 Nf4? {26...Bc8 27.Qa8 Qd8} 27.Qxb7??? {27.Rxf4! exf4 28.Qxb7 =} Ne2#
