Alekhine Defense Four Pawns Attack Exposed King in Chess

In the Alekhine Defense Four Pawns Attack, the defining feature is White’s central pawn surge (often after 1.e4 Nf6 2.e5 Nd5 3.d4 d6 4.c4) that leaves the king somewhat exposed. The “exposed king” motif appears when White’s king is forced to defend the center while Black uses the extra tempo and piece activity to attack the king’s safety.
