1.d4 Nf6 2.c4 e6 3.Nf3 d5 4.Bg5 Be7 5.Nc3 0-0 6.e3 Nbd7 7.Be2 a6!? {7...dxc4 8.Bxc4 c5 9.0-0 a6 10.a4 = can occur after 7.Bd3 too.} 8.0-0 dxc4 9.Bxc4 {9.a4 was possible, when 9...c5 10.Bxc4 transposes to 7...dxc4 etc.} b5 10.Be2 Bb7 11.Qc2 Rc8 12.Rac1 {After 12.R(either)d1 c5 13.dxc5 Black can recapture with the rook.} c5 {This is =/+ according to my machine, which prefers Qb3 to White's next.} 13.Qb1 h6 {At least as good is 13...cxd4 and after 14.Nxd4 b4 15.Nd1 Qa5 16.Rxc8 Rxc8 17.f4 only the size of Black's advantage is debatable.} 14.Bh4 c4 {Now it's =. Instead 14...cxd4 is =/+, but I wanted to unbalance the game a little more.} 15.Nd2 {15.Qc2!?} e5 16.dxe5 {Better 16.Bf3=} Nxe5 {=/+} 17.Rfd1 Qb6 {Better 17...Nd3.} 18.Bg3 {=} Qe6 19.Bxe5 Qxe5 20.Bf3 Bxf3 21.Nxf3 Qc5 22.a3 {22.e4!?} Rfd8 23.Nd4 {Better 23.Qc2.} Bd6 {=/+} 24.Nde2 Qh5 25.Ng3? {Better 25.h3.} Bxg3 26.hxg3 Qe5? {In a time scramble Black misses 26...Ng4 27.Qe4 Rd3! -+} 27.Rc2 {Better 27.Rxd8+ =/+.} Rd6 {Better 27...a5 -/+.} 28.Rcd2 {White offered a draw here.} Rcd8 29.Qc2 {It was better to trade all the rooks off and then play his queen to f5, which White could do next turn as well. Now Black should himself do this, with a larger advantage than before.} R8d7 30.Ne2 Rxd2 31.Rxd2 Rxd2 32.Qxd2 Qd5 {Better 32...Qf5 -/+.} 33.Nd4 {33.Qxd5 =/+.} Qe4 {=/+} 34.Qd1 Nd5 35.Qd2 {Better 35.Kh2} Qb1+ {-/+} 36.Kh2 Nf6 37.f3 {37.Qe2!?} Qd3 38.Qe2? {Losing.} Nd5 39.e4 {A slow defeat follows 39.Qe1 Qxe3} Ne3! 40.Qxd3 cxd3 41.Nb3 Nc4 0-1

Ne7 {8...f6!? was possible, though White may still have a slight edge then too.} 9.Bh6 0-0 {My machine suggests 9...Bxh6 10.Qxh6 Nc6 +/=}10.h4 Nf6 {Now it's +/-; instead a toughter defence could begin with 9...f6.} 11.h5 gxh5? {+-; 11...Ng4 was preferable.} 12.g4! {12.Bxg7 Kxg7 13.e5 +/-.} Nxg4 {12...h4 13.Nxh4! is +- according to my machine.} 13.Bxg7 Kxg7 14.Qg5+ Ng6 {14...Kh8 15.Qxh5 Nf6 16.Qh2 +-} 15.Qxh5 Nf6 16.Qh6+ Kh8 17.e5 dxe5 18.dxe5 {My engine sees mate in 12 moves beginning with 18.Ne4.} Nxe5 19.Nxe5 Qe7 20.Nc6 {It's now mate in 11, fwiw.} 1-0

Rxf3.} Rxf3 42.Rxf3 Re5 43.Kg3 f5 44.Ra3 Kf6 45.Ra6+ Re6 46.Ra3 Rd6 47.Rb3 h5 48.gxf5 {48.Ra3!?} gxf5 49.Re3 {49.Rb8!? or even 49.Kh4!?} Rd4 {The machine thinks Black is winning now, but White should still draw.} 50.Ra3 Kg5 51.Rb3 Re4 52.Kf3 Rf4+ 53.Ke3 Ra4 54.Kf3 Ra1 55.Rb8 Ra3+ 56.Kg2 h4 57.Rg8+ Kf4 58.Rf8 Ra2+ 59.Kf1 {59.Kg1 avoids losing a second pawn, at least for the time being.} Ke4!? {59...Rh2 could have won a pawn, but then the game is still theoretically drawn after, say, 60.Ra8.} 60.Kg1 {60.Rb8 Ra3 61.Kg2 Rg3+ 62.Kh2? (Better 62.Kf2) Rd3 63.Kg2 Rd2+ 64.Kg1 Ke3 allows Black to win.} f4 61.Rh8 Ke3 62.Re8+? {Better 62.Rb8.} Kf3 {-+} 63.Rg8 Ra1+ 64.Kh2 Ke3 65.Re8+ Kf2 66.Rb8 Ra2 67.Re8 f3 68.

1.e4 b6 2.d4 Bb7 3.Bd3 Nf6 4.Qe2 Nc6 5.c3 e5 6.d5 {This is like 1...Nc6 2.d4 e5 (The Kevitz Variation) 3.d5.} Ne7 7.Nf3 Ng6 8.h4 h5 9.Bg5 {Instead 9.g3 c6 10.d5 Bb4+ 11.Nbd2 was played once in a GM game.} c6 {Sometimes Black does this in the Kevitz, hoping to undermine White's centre, which would have extra force here thanks to the B/b7, if Black succeeded.} 10.c4 Be7 11.Nc3 Ng4 12.g3 a6 {Better 12...Bxg5 =.} 13.0-0 {Better 13.d6! +/= after 13...Bf6 14.Bc2 or 13...Bxg5 14.hxg5 when Black must worry about tactical problems with his N/g4, although over the board I didn't feel confident about this somehow.} Bxg5 {=} 14.Nxg5 0-0 15.Nd1 cxd5 16.cxd5 f6 17.Nf3 {17.Nh3!?} Ne7 {17...d6!?} 18.Ne3 Nh6 {Better 18...Nxe3.} 19.Nd2 {+/=} g6 20.Nec4 {20.Rfc1!?} Nf7 21.a4 Bc8 {This is one downside to this line compared to the Kevitz; the bishop sometimes needs to return to c8; another possible downside is that ...b6 might turn out to be weakening and/or a loss of time.} 22.Rfc1 {22.f4!? was suggested by my opponent afterwards as possibly giving me a strong attacking position, but the computer continues to give Black only a slight disadvantage after 22...d6.} d6 23.Rc2 {23.a5!? b5 24.Nb6 is suggested by my engine, with still a slight advantage.} Kg7 {Better here or next move is...f5 +/=.} 24.b4 {The machine claims a large advantage for White after 24.a5 b5 25.Nb6 Rb8 26.Rac1. Playing a4-a5 on my next turn also would have been +/- according to it.} g5 25.hxg5 {+/-} Nxg5 {My opponent was in time trouble by now, though I later was too.} 26.Qe3 {26.a5!?} Rb8 27.f4 {27.Kg2!?} Nf7 28.fxe5 {28.Be2!?} fxe5 29.Rf1 {Better 29.Be2} Ng6 {+/=; 29...Ng8!? +/=} 30.Nf3 {30.b5!?} Bh3 {30...b5!?} 31.Rff2 Bd7 32.Nb2 b5 33.a5 {33.axb5!?} Rb7 {33...Rc8!?} 34.Rh2 {34.Kf1!?} Bg4 35.Nh4 {Now the game is = according to the computer, which still claims an edge for White after 35.Be2.} Nxh4 {35...Qg5!?} 36.gxh4 Nh8 {Better 36...Rc7.} 37.Be2 {Better 37.Rc6 +/=; now the game is again =.} Ng6 {37...Rbf7!?} 38.Bxg4 hxg4 39.Rcg2? {Better 39.Qg3.} Qf6? {Better 39...Rbf7 -/+.} 40.Qe2 {The machine claims +/= after 40.Qe1.} Rc7 {40...Nf4 also would be = according to the computer, though in practice Black's position is more pleasant regardless since he has the initiative.} 41.Nd3 {41.Rxg4!? =} Rc2 42.Qd1 Rxg2+ 43.Rxg2 Qxh4 44.Rxg4 Qh3 45.Nf2 {Better 45.Qe2.} Qe3 46.Qc2? {Better 46.Rg2 =/+.} Kh6 {Better was ...Qe1+ first, winning according to my engine.} 47.Kf1 Qh3+? {Instead 47...Qd4 -/+.} 48.Kg1? {48.Rg2 is = according to the machine, but in time trouble I failed to see that 48...Nf4?? would hang Black's queen.} Rxf2! {-+} 49.Rxg6+ Kxg6 50.Qxf2 Qg4+ 51.Kf1 {51.Qg2 leads to a lost pawn ending.} Qxe4 52.Qb6 52.Qc4+ 53.Kf2 53.Qf4+ 54.Kg2 e4 55.Qxa6 e3 56.Qxb5 Qe4+_ 57.Kf1 Qf3+ 58.Kg1 e2 59.Qe8+ Kg5 60.Qe7+ Kg4 61.Qe6+ Kf4 62.Qxd6+ Ke4 63.Qg6+ Kd4 64.Qb6+ Kd3 65.Qa6+ Kd2 0-1
