This repertoire book for White 1.d4 players advocates a dangerous gambit continuation which can be used against the Slav, Semi-Slav and Triangle defences. The author extended the repertoire to include lines against the Orthodox Queen's Gambit with ..d5; and ..e6; by Black. In this case he recommends the Catalan set-up for White, offering ideas against both the open defence, where Black takes on c4, and the closed defence.
The central idea against the Slav and Semi-Slav is 1.d4 d5 2.c4 c6 3.Nf3 Nf6 4.Nc3 dxc4 5.e4 b5 6.Be2 (the Geller-Tolush Gambit) or if 4...e6 5.g3 In both cases White sacrifices the c4-pawn, proposing a real gambit. If Black does not take on c4, White plays g3 - the Closed Catalan.
The Triangle System can transpose to the Geller-Tolush Gambit after 3.Nf3 e6 4.Nc3 dxc4 5.e4 b5 or to the Semi-Slav Catalan setup after 5.g3.
If Black plays the orthodox Queen's Gambit then White continues with 1.d4 d5 2.c4 e6 3.Nc3 Nf6 4.Nf3 Be7 5.g3 0-0 6.Bg2. Now ..c6 would transpose to the Closed Catalan, while 6...dxc4 7.Ne5 has similarities to the plan against the Semi-Slav.
After 6...dxc4 7.Ne5; second players answer almost automatically 7..Nc6?!, when 8.Bxc6! bxc6 9.Nxc6 Qe8 10.Nxe7+ Qxe7 11.Qa4 has been assessed as toothless for many years, but lately White has found the right keys to Black's position. After 11..c5! 12.dxc5 Qxc5 13.Be3 Qc7 14.f3! first players score the incredible 75% in OTB games.
The proposed repertoire is not a hit-and-run tactic! It is meant to withstand thorough home preparation. Sometimes the engines will show "equal" evaluations, but they do not recognize the initiative as a crucial factor. Also the cost of Black's mistakes is higher.
