English Opening Jaenisch Gambit (1.c4 b5) Chess Puzzles

The English Opening Jaenisch Gambit is a rare English-side pawn sacrifice where White aims to provoke weaknesses and gain activity rather than hold every pawn. I don’t know the exact, widely accepted move order that uniquely defines this specific Jaenisch Gambit within the English Opening family, so I can’t safely list a precise “defining move sequence” without risking mixing it up with a sibling line. What you can reliably look for is the characteristic feature: White offers a pawn early from the English setup to accelerate piece play and restrict Black’s development.
