How the Alekhine's Defence: Wins a Pawn (Gronchevsky–Ohlin) works
The Alekhine's Defence: Wins a Pawn (Gronchevsky–Ohlin) is a classic chess opening trap arising from the Alekhine's defence. In this line Black wins decisive material by move 6, punishing a natural-looking but losing idea from White.
The full sequence runs 1.e4 Nf6 2.Nc3 d5 3.e5 Ne4 4.Nce2 d4 5.c3 dxc3 6.Qa4+. Each move looks reasonable, which is exactly why the trap is so effective over the board — White walks into it while trying to play "normal" developing moves.
This pattern is well known from master and correspondence play (Gronchevsky - Ohlin, 1973.??.??). Recognising it early lets you either spring it as Black or sidestep it as White.
