4...c5
[edit | edit source]This is the main line of the Winawer variation. Black has just pushed forward his c pawn with 4...c5, threatening White's pawn chain. White's knight on c3 prevents them from extending the chain by moving a pawn to c3, so this puts White's central pawns in danger.
However, c5 also blocks the escape route for Black's dark-squared bishop. White usually takes advantage of this to regain the initiative with 5. a3. Black usually trades bishop for knight with 5...Bxc3+ 6. bxc3.
