Albin Countergambit
1.d4 d5 2.c4 e5 3.dxe5 d4 4.Nf3 Nc6 5.g3
This move, which seems to have been first played by Chigorin against Albin in 1896, is the main line in ChessBase's 2021 Mega database, ahead of 5.a3 and 5.Nbd2.
5...Nge7
Morozevich is credited with popularising this reply in modern practice.
6.Bg2 Ng6 7.0-0 Ngxe5
Black has won the sacrificed pawn back by fairly unsubtle means and now threatens to go a pawn up by snaffling the c4 pawn.
8.Nxe5 Nxe5 9.Qb3!?
The c4 pawn was not hanging after the exchange of knights as ...Nxc4?? loses the knight to Qa4+ etc, but now it is directly defended and White puts pressure on b7.
The main move in Mega21 is 9.b3, after which 9...Bc5 10.Bb2 0-0 11.Nd2 is the most-popular continuation, slightly favouring White, according to Stockfish14 and Komodo12.1.1.
9...c6
9...Be7 has been played by English grandmaster Simon Williams and future Russian GM Sergei Zablotsky, although both played ...c6 a few moves later.
10.Rd1 Qf6?!
Indirectly defending d4 thanks to the threat of ...Nf3+. The engines much prefer 10...Bc5, although they like White after 11.Nc3!? (but not 11.e3? Bg4, when Black is very active).
11.Nd2 Qe6!?
This apparent-novelty does not solve Black's problems, but is preferred by the engines to the known move 11...Bc5, when 12.Ne4 is strong, eg 12...Qe7 13.Nxc5 Qxc5 14.e3!? Qxc4 15.exd4 Qxb3 16.axb3 Ng6, with White having a large advantage after both 17.Re1+ and 17.d5, according to the engines.
12.Ne4 f5?
Better is 12...Qxc4, but both 13.Qxc4 and 13.Bf4!? are strong, according to the engines.
13.Rxd4! fxe4?
Again Black has a better alternative, this time in 13...Be7, but the engines much prefer White after 14.Ng5 or 14.Bf4.
14.Rxe4 Bd6 15.f4 0-0 16.fxe5 Bc5+ 17.Be3
