declines gambit for present

( 5...e6 6.cxd4 is more standard )

develops a piece, but it is attacked right away

( 6.cxd4 probably the better move since it gives white solid control of center with no loss in P power 6...e6 7.Bc4 )

( 6.Qxd4 e6 7.Bc4 Nc6 8.Qd3 Nb6 B gets inconveniently attacked )

( 7.Qxd4 Nc6 8.Bxf7+? nice idea but it doesn't work 8...Kxf7 9.Qf4+ Ke8 10.Ng5 Qc7 11.Qf7+ Kd8 12.e6 Qe5+ )

( 7.Qe2 d5 B is forced back )

( 7.Qb3 d5 8.exd6 Nxc4 9.Qxc4 Nc6 10.O-O Qxd6 = white has lost whatever initiative was there )

( 7.Bb3 mephisto2: this is more in the spirit of the gambit 7...d5 8.exd6 Qxd6 9.O-O )

now the gambit is accepted, but even though white has 3 pieces developed to black's 1, it is not as advantageous for white as when the B is on c4

( 10.Bf4 d5 11.Rc1 mephisto2: a french-like position where the d-pawn is also often sacrificed for position )

( 10.Bg5 from montagues 10...Be7 ( 10...Qc7 11.Rc1 ) ( 10...f6 11.exf6 gxf6 12.Bf4 ) 11.Bxe7 Qxe7 12.Qb3 Qd8 13.Ne4 O-O 14.Nd6 )

( 10...Qc7 11.Rc1 Nxe5 12.Nxe5 Qxe5 )

( 12.Rc1 O-O 13.Bxh7+ Kxh7 14.Bxb6 Qxb6? ( 14...Bxh2+! this is why the previous idea doesn't work 15.Nxh2 ) 15.Ng5+ drawing the K out 15...Kg6 16.Qxd6 )

( 12.Qe2 O-O 13.Bxb6 Qxb6 14.Bxh7+? Kxh7 15.Ng5+ Kg6 16.Qg4 f5! )

( 12.Qd2 O-O 13.Bxb6 Qxb6 14.Bxh7+ Kxh7 15.Qxd6 Rd8 16.Qf4 Kg8 )

( 12.Be4! mephisto2: white avoids black's Nb4 without losing a tempo 12...Nb4?? 13.Qd4 )

now we go on an exchange binge which i think proves to be counterproductive to the intent of the morra gambit

( 13.Rc1 O-O 14.Ne4 Bc7 15.Nc5 )

( 13.Qe2 O-O 14.Rfd1 Nd5 )

( 13.Nd4 Nxd4 14.Bxd4 O-O 15.Qg4 e5 )

( 13.Qb3 Nd7 )

( 14.Qc2 O-O 15.Bc5 Re8 16.Rfd1 Nd7 17.Bxc6 bxc6 18.Bd6 Bb7 )

( 14.Bc5 Ne7 15.Qxd8+ Bxd8 16.Ne5 )

mephisto2: Queen exchange looks in favour of black with a pawn up

( 15.Bc5 Qxd1 ( 15...Nd7 16.Bd6 ) 16.Rfxd1 Rb8 17.Bd6 ( 17.b4 Nd7 18.Ne4 Nxc5 19.Nxc5 ) 17...Bxd6 18.Rxd6 Nc4 19.Rxc6 Nxb2 20.Rb1 O-O 21.Rc7 Rb6 22.Ne5 )

( 16...O-O 17.Ne5 f5 18.Nxc6 ( 18.Nd6 Bf6 ) 18...fxe4 )

( 16...Nc4 17.Bd4 O-O 18.Rac1 )

this was the point of all that exchanging: to stop the black K from castling, allowing which might have been a good idea actually since the K would be away from the center

( 17.Bxb6 Bxb6 18.Nd6+ Ke7 19.Nxc8+ ( 19.Rfd1 Rd8 ) ( 19.Ne5! from montagues ) 19...Raxc8 20.Ne5 Bd4 )

( 17.Nc5 e5 )

( 18.Rfd1 Bb7 )

rest of game white tries to get back the P

( 22.Nd4 e5 23.Nf5 g6 24.Nd6 )

black will leave the N pinned an extraordinarily long time

( 22...Rb8 23.Rc2 Rd8 24.Nd4 Ba6 25.a4 g6 ( 25...e5 26.Nf5 Rg8 ) 26.Ba3 Rb6 )

( 23.b4? Be2 )

( 25...Nxb4 26.Nxc6+!? ( 26.axb4 Rb6 this looks pretty good ) 26...Nd5 27.Nxb8+ Rxb8 )

( 26...Nxb4 27.axb4 g6 28.Nxc6+ Ke8 )

( 27.g3 Nxb4 28.axb4 Ke7 29.Nxc6+ Kf8 )

( 27...Nxb4 28.axb4 e5 29.b5 exd4 30.Rxd4+ Ke6 31.bxa6 )

( 27...e5 28.Nxc6 )

done to give the K a chance to move out, but it really doesn't serve any purpose since there is nowhere to go

( 29.Nf3 e5 30.Nh4 Rg8 31.Nf3 e4 32.Nd4 Bd3 33.Rc1 = )

( 29.g3 e5 30.Nxc6 Kxc6 31.Bb4+ Kb6 32.Rxc8 Rxc8 33.Rxd5 = )

( 32.Rcd1 e5 33.Nf5 Ke6 ( 33...Rb5 34.Bb4 Ke6 ) 34.Ng7+ Kf7 35.Nf5 )

( 33...e5 34.Nxc6 Rxc6 35.Rxd5+ Ke6 )

( 34...Nxb4 35.axb4 )

( 35.Rcc2 e5 36.Nxb5 Rxb5 )

( 35.Rdc2 e5 ( 35...Nxb4 36.axb4 e5 37.Nxc6 Bxc6 38.Rxc6 Rxb4 39.Rxf6 Rxb2+ 40.Ke3 R8b3+ 41.Ke4 Rxg2 42.Kxe5 Re2+ 43.Kf5 Rxf3+ 44.Kxg5 ) 36.Nxc6 Bxc6 37.Rxc6 Nxb4 38.axb4 Rxb4 39.Rxf6 Rxb2+ 40.Ke3 a3 41.Ra6 R2b3+ 42.Ke4 R8b6 43.Ra5 Kd6 44.Kf5 )

( 35...e5 36.Nxb5 Rxb5 37.bxa4 R5b6 38.a5 Ra6 39.Rc5 )

( 36...Rxa4? 37.Nb3 Kc8 38.Nc5 Nxb4 39.Nxa4 Bxa4 40.axb4 Rxb4 41.Rd6 Rb2+ )

( 37.Re1 Nxb4 38.axb4 e5 39.Nb3+ Ke8 40.Nc5 Rxb4 41.Rd6 Rb2+ 42.Ke3 Bb5 43.Ke4 Rc2 )

( 39...Ke6 40.Nc3 Nxc3 ( 40...Nxb4 41.Nxa4 ) 41.Rxc3 Kf5 )

( 40.Bc3 Ke6 loses R's xray of K )

( 42.Na4 Ke8 43.Rc1 )

( 42...Ke6 43.Na4 Rxb4 44.axb4 Rxb4 45.Nc5+ Kd6 46.Nb7+ Rxb7 47.Rxc4 )

( 42...Bb5 43.Nxd5 )

( 42...Rxb4! 43.axb4 Rxb4 mephisto2: leaving 2 Ps for the exchange )

( 44.Bc5 Ke6 45.Nb2 Nb6 46.Rcd1 Kf7 47.Nd3 Nc4 48.Re2 Nxa3 49.Nxe5+ Kg8 )

( 44.Ne3 Ke6 45.Bc5 Rd7 46.Ra1 Nf4 47.Rxd7 Kxd7 48.Kg1 )

this is probably the wrong time to remove the pin since it allows the exchange

( 45...cxb5 46.Rc6+ Kf7 )

( 46.Rd6+ Ke7 47.axb4 Ra2+ 48.Ke3 ( 48.Kg1 cxb5 49.Rd5 Re2 50.Kf1 Re3 51.Rcc5 Ke6 52.Kf2 f4 53.Rxb5 Rxb5 54.Rxb5 Rb3 ) 48...cxb5 )

( 46...cxb5 47.Rc6+ Kf7 48.Rc5 Re8 49.Rdd5 )

at last the P has been regained and we can force a draw - the sequences that follow is an attempt to see if there was a way to win for white

( 48.Re2 (D)


idea shall be to get black K deep into back ranks into Qside so we can eliminate Ps on Kside - unfortunately, it doesn't seem possible to get the black K far enough away, so we didn't attempt this (the 48.Re2 line shown actually appears to win, but this is because black makes poor moves) 48...Ra4 ( 48...Rab8 49.Rc5 Kf6 50.Rxb5 Rxb5 51.Rb2 e4 52.fxe4 ( 52.g4 hxg3+ 53.Kxg3 f4+ 54.Kg4 exf3 55.Kxf3 Kf5 56.Rb3 ( 56.Rc2 Rxb4 57.Rc5+ Kf6 58.Kg4 Rb1 59.Rf5+ Ke6 60.Rxg5 Rf1 61.h4 f3 62.Kg3 Kf6 63.Rg4 Ke5 64.h5 Rg1+ 65.Kxf3 Rxg4 66.Kxg4 Kf6 67.Kf4 Kf7 68.Kf5 Kg7 69.Kg5 Kh7 70.h6 Kg8 ) 56...Ke5 57.Kg4 Ke4 58.Rb1 Ke3 ) 52...fxe4 53.Ke3 Ke5 ) ( 48...Rxb4 49.Rxe5+ Kd7 50.Rc2 Rf8 ) ( 48...Kd7 49.Rf6 f4 50.Rg6 ) 49.Rc5 Rxc5 50.bxc5 Ke6 51.Rc2 Ra7 52.g4 ( 52.Rd2 Ra6 ) ( 52.Ke3 Kd5 53.c6 Rc7 54.Kd3 Rxc6 55.Rxc6 Kxc6 56.Kc4 ) ( 52.Ke2 Rc7 53.Kd3 Kd5 54.c6 Rxc6 55.Rxc6 Kxc6 56.Kc4 ) 52...fxg4?

draw by repetition - we look to see if there was anything else that could have been done particularly with 51.Rcd7 which is effectively countered with 51...e4 - all roads seem to lead to a draw or a black win since it is not possible to stop the loss of the bP
