Polish Opening: Main LineEdit
2...Bxb4Edit
Black takes the undefended pawn which almost definitely causes 3. Bxe5 from white. Now not only has black lost a central pawn for a flank pawn, but black also has to worry about white's threat on g7. However, white can play 3. f4!?. After this point, black can safely gain a more or less equal game with 3... d6 4. fxe5 dxe5 5. Bxe5 , where black has a slight advantage (due to white's weakened kingside and missing f-pawn), but has traded two central pawns for two flank pawns, which therefore reduces the advantage to almost nothing. On the other hand, black can accept the gambit with 3... exf4!?, where it results in wild play after 4. Bxg7 Qh4+! 5. g3 fxg3 6. Bg2! gxh2+ 7. Kf1 hxg1=Q+ 8. Kxg1 Qg3 9. Bxh8, where white has a rook and a pawn for a knight and three pawns. The board is wide open and both sides have possibilities. Nevertheless, computer evaluation has suggested that 3...Nh6! gives black a small advantage.
