Lobster Gambit
The Lobster Gambit is a countergambit (attack on Latvian Gambit).
It starts with 1. e4 e5 2. Nf3 f5 (Latvian Gambit, aggressive response to the King's Pawn Opening, which is not very popular move for black). Normal choices against this gambit are accepting with 3. exf5 or 3. Nxe5, or even ignoring the gambit with the developing move 3. Nc3.
Black played a risky opening and now is a bit unstable, and now White can guarantee an advantage by playing solidly by the principles. Simple play with no blunders should expose Black's weakness eventually.
White can choose between capturing 2 pawns.
BUT NO!
White plays 3. g4!!! Extremely delulu move. This is super rare position. Even the computer evaluation is -2.38.
If white is lucky enough, it can get away with this terrible position. But it depends on which pawn is Black going to capture.
If Black accepts it (3. fxg4), White can capture on e5 and can gain some initiative due to having some center control. In some cases it can reach an advantage of +0.5, but it is still risky play this gambit for a win.
In most cases Black captures 3. fxe4, White is under a great pressure. Best move is to take on e5, but Black starts harassing the knight, which most often gets taken several moves later by the bishop on f5, creating double pawns.
