Two Games

RMD-ALD, 2/12/2005 [B20]

1.e4 c5 2.e5 Nc6 3.Nf3 e6 4.Bb5 Qc7 5.Qe2 {5.Bxc6 Qxc6 6.O-O ...1/2-1/2, Koc Przemyslaw 2330 - Bus Mariusz 2370, Wisla 1998} d6 {5...Nge7 ...1-0, Kuindzhi Alexander - Keogh Eamon, Hague 1961} 6.d4!? cxd4 7.Nxd4 dxe5 8.Nxc6 bxc6 9.Ba4 {9.Qf3!?} Qa5+ {9...Bc5} 10.Nc3 Nf6?? 11.Bxc6+ Ke7 {I might as well just have resigned at this point.} 12.Bxa8 g6 13.O-O? {13.Bd2 Qb6 14.O-O-O} Ba6 14.Qf3 Bxf1 15.Bg5 {A very good in-between move, so White can recapture Rxf1 instead of Kxf1. However, 15.Qb7+ was even stronger.} Bg7 16.Rxf1 {16.Qb7+} h6 17.Bh4 g5 18.Bg3 Rd8 19.h4 e4 20.Bxe4 Nxe4 21.Qxe4 Bxc3 22.bxc3 Qxc3 23.Qh7 {23.Be5!} Rh8 24.Qd3Qc6?? {Of course, trading queens loses. However, not trading queens loses even faster.} 25.Qa3+! 1-0 {25...Kf6 26.Qb2+ Ke7 27.Qxh8 Qd5 28.Qxh6 g4}

ALD-RMD, 4/24/2005, [D06]

1.d4 d5 2.c4 Nf6 {My wife's standard response to the Queen's Gambit, but not altogether satisfactory.} 3.Nc3 Bf5 {3...dxc4} 4.Bg5 Ne4 {4...e6} 5.Nxe4 Bxe4 6.f3 {As I played this, I had second thoughts about whether this was best. However, post-mortem analysis seems to indicate that this was ok after all.} Bg6 7.e3 {7.Qb3 ...1-0, Suabedissen R - Fischer Jakob, Wewelsburg 1996} Nc6 8.Bd3 {8.Qb3} Qd6 {8...dxc4 9.Bxc4 f6 =} 9.Qb3 {I couldn't see this at the time, but this move unleashes a quasi-forced sequence that leads to the loss of pawn; 9.c5!} Qb4+ 10.Qxb4 Nxb4 11.Bxg6 hxg6 12.Kd2 {My wife criticized this move, but analysis bears it out. This is the strongest way to prevent ...Nc7. However, now White goes down a pawn with no compensation.} dxc4 13.Nh3 {Right after I played this I spotted the stronger 13.e4.} f6 14.Bf4 {14.a3 Nd3 15.Bf4 c5} Nd5 {14...O-O-O} 15.Rac1 b5 16.e4 Nb4!? {16...Rxh3! 17.exd5 (17.gxh3? Nxf4) Rh5 18.Bxc7 Rxd5 but not 16...Nxf4? 17.Nxf4} 17.a3? {17.Bxc7 is the only reasonable move here.} Nd3 18.Rc2? e5? {18...Rxh3 19.gxh3 Nxf4} 19.dxe5? {19.Be3 O-O-O 20.d5} fxe5? {19...Rxh3 20.gxh3 Nxf4 21.exf6 gxf6} 20.Bg3 O-O-O 21.Ke2 Bc5 {21...Be7} 22.Rd1 {22.Ng5} Bd4 23.Rb1 Rh5 {A very odd position for the rook; 23...a6} 24.f4 {24.b3 g5 =} a6 {24...exf4! 25.Nxf4 Nxf4+ 26.Bxf4 Rf8} 25.fxe5 Nxe5 {25...Bxe5! 26.Bxe5 Rxe5} 26.Nf4 Rh6 {An even odder move than 23....Rh5 since the pawn is already defended by the knight; 26...Rhh8} 27.Ne6 Ng4 {Black has dissipated her advantage. Now despite the extra pawn, this position is equal or even microscopically in White's favor; 27...Rd6} 28.Nxd8 Kxd8 29.Rd2 c5 30.h3 {I worried about this move after making it, but analysis confirmed my over-the-board instinct.} Ne3? {30...Nf6} 31.Kf3? {31.Bf4 Nxg2 32.Bxh6 gxh6} Ke7? 32.Bf4 c3 33.bxc3 Bxc3 34.Bxe3 {34.Rd3 is even stronger.} Bxd2 35.Bxd2 {The rest of the game is just a matter of technique.} Rh8 36.Bg5+ Ke6 37.Kf4 {37.Rd1} Rf8+ 38.Ke3 Rc8 39.Rd1 a5 40.Bf4 Rc6 41.Kd3 b4 42.axb4 cxb4! {42...axb4? 43.Kc4! letting the king in next to the pawns, so in this case the general principle of recapturing towards the center has to be violated. - RMD} 43.Rc1 Kd7? {43...Ra6! not just avoiding the exchange of rooks but placing the rook on a strong square behind the passed pawn.} 44.Rxc6 Kxc6 45.Kc4 Kd7 46.Be5 Ke6 47.Bxg7 Kd7 48.h4 Ke6 49.g4 Kf7 50.Bd4 Ke6 51.h5 Kf7 52.hxg6+? {Prolongs the game unnecessarily; 52.h6!} Kxg6 {With my next move I embarked on a totally wrong strategic plan, leaving my king to deal with Black's two passed pawns while the bishop tried to help my own pawns advance. This is completely backwards. I should have played 53.e5 and prepared to move my king forward to help the pawn queen while my bishop dealt with the Black pawns.} 53.Be3 Kf6 54.Bf4 Ke6 55.g5 Kf7 56.Bc7 Kg6 57.Bd8 {57.Bxa5 was a quicker win.} Kh5 58.e5 Kg6 59.Kb3 {59.e6! and the pawn cannot be stopped.} Kf5 60.Bf6 Ke6 61.Ka4 {I don't understand why I was playing such a slow game. This game could probably have been won in 15 moves fewer than it took me; 61.g6} Kf7 62.Kxa5 b3 63.Kb4 b2 64.e6+ Kxe6 65.Bxb2 {Black should have resigned here.} Kf7 66.Bf6 Kg6 67.Kc5 Kf5 68.Kd6 Kg6 69.Ke7 Kf5 {White: 0:37, Black: 0:41} 70.Kf7 1-0
