Following on from my posts on the Budapest’ and Caro-Kann, I realized that these were in alphabetical order but that I had missed out A. To put this right here’s another dodgy line for Black, the Albin Counter Gambit with 1.d4 d5 2.c4 e5. As with the Budapest I have some sympathy with Black’s attempt to show that 2.c4 is not a developing move but it still looks somewhat dubious. Alexander Morozevich tried to rehabilitate the Albin with 3.dxe5 d4 4.Nf3 Nc6 followed by 5…Nge7, but this seems hopeful after 5.Nbd2 Nge7 6.Nb3 Nf5 7.e4 dxe3 8.Qxd8+ Nxd8 9.fxe3, with Black being a doubled pawn down in the endgame.
The following game features another decent fourth move for White in 4.a3, though after 4…Nc6 he should then play 5.e3 as covered by Mikhail Shereshevsky in The Soviet Chess Conveyor. This line has also been played by Alexei Alexandrov, and it has the advantage of doubling as a line against the Chigorin via the move order 1.d4 d5 2.c4 Nc6 3.e3 e5 4.dxe5 d4 5.a3.
I think I might make this into an alphabetic series, but there could be a problem with ‘X’. I thought I might cheat with X-terminate ’em with the English but if anyone has a better idea please let me know.
