Polish Opening Birmingham Gambit (1.b4 c5) Chess Puzzles

The “polish opening birmingham gambit” is a named gambit line within the Polish Opening family, defined by a specific pawn sacrifice theme that aims to accelerate development and open lines against the opponent’s king. However, the exact, widely accepted move order that uniquely distinguishes this Birmingham Gambit sub-variation is not consistently documented in mainstream databases, so I can’t responsibly give a definitive move sequence without risking confusion with a sibling line.
