1.d4d52.c4e63.Nc3a6⩲The same move
as last game, just a move earlier, which has been attributed to Janowsky, who
(according to my database) played it eight times between 1899 and 1902, with
the pitiful record of 1/7/0.4.cxd5exd5Now we essentially have the
Carlsbad variation.5.Nf3Nf66.Bg5c67.e3Be78.Bd3Nbd79.Qc2h610.Bh4O-O11.O-ONe8?!When White has played Nf3 in the Exchange variation,
Black's typical freeing maneuver is ... Nf6-e4, once Black has the e4-square
fully protected. For example,11...Re812.Rae1Ne4⩲leaves Black
better off than the text.12.Bg3Ndf613.h3Nd614.Ne5g6?+−This
was likely intended to prepare Bf5, but it allows for a devastating
sacrificial attack.14...Be6⩲keeps Black in the game.15.Bxg6!fxg616.Qxg6+Kh817.Qxh6+Kg818.Ne2?⩲...18.Qg5+Kh719.Bf4+−keeps the pressure on.18....Be6?+−18...Bf519.Qg5+Kh720.Nxc6bxc621.Bxd6Bxd622.Qxf5+Kh623.Nf4Bxf424.Qxf4+Kg7⩲and while White
has a very slight material advantage, Black has an extra piece, and can
coordinate forces and defend his weaknesses easily. Black is still very much
in the game.19.Nf4Nf5?19...Bf720.Neg6Nh721.Nxe7+Qxe722.Ng6Qe623.Ne7+Qxe724.Bxd6Qg525.Bxf8Rxf826.Qxg5+Nxg5+−White has a
