1...b5?
[edit | edit source]The worst possible response to 1. e4. Black gives up their b-pawn which White can snap up while developing their bishop, 2. Bxb5.
Having opened the b7 square, Black can fianchetto 2...Bb7 to attack White's centre from afar. (cf. the Owen's defence, 1...b6.) One devious try for Black is to take advantage of having brought White's bishop away from defence of the g2 square. 1. e4 b5? 2. Bxb5 Bb7 3. Nc3 f5?! 4. exf5 and Black thinks ...Bxg2?! wins the rook in the corner. Unfortunately, Qh5+ and Black's king proves to be too weak.
If White does not accept the pawn, play may transpose into the Polish gambit in the Sicilian defence after 2...Nf3 3. c5.
History
[edit | edit source]1...b5? is unheard of in tournament chess and almost never played in online games.[1] It resembles a Polish opening in reverse, but Black, moving second, is down a tempo.
