Alekhine Defense Two Pawns Attack Discovered Check in Chess
In the Alekhine Defense Two Pawns Attack, Black often plays ...d5 and then ...c5 to challenge the center while keeping pieces active. The “discovered check” idea happens when a pawn move (commonly the c- or d-pawn advance) opens a line so that a rook or bishop suddenly gives check, while the moving pawn itself was the key to uncovering the attack. The defining feature is that the check is revealed by the pawn’s advance, not by a direct piece move to the checking square.
To spot this motif, look for moments when your pawn move on the c- or d-file both attacks White’s center and clears a diagonal or file for your bishop/rook to attack the king. In the Two Pawns Attack structures, try to calculate whether the pawn push also forces White’s king into a vulnerable line—especially if White’s pieces are temporarily blocking that line. To use it, time the pawn advance so that the discovered check comes with tempo (often winning a piece or gaining decisive initiative) before White can respond by capturing the uncovering piece or closing the line.
Frequently Asked Questions: alekhine defense two pawns attack discovered check
- What exactly makes it a “discovered check” in the Alekhine Defense Two Pawns Attack?
- It’s discovered because the check appears only after a pawn move opens a line for a bishop or rook. In this motif, the pawn thrust (typically c- or d-pawn related) is the move that reveals the attacker, creating the check with tempo.
- Which pawn moves are most likely to create the discovered check?
- The most common are advances that open a diagonal or file for your long-range piece—often involving the c-pawn or d-pawn in the Two Pawns Attack plans. The key is not the exact square every time, but whether the pawn push clears the line to the king.
- How can I recognize the setup before I play the pawn?
- Before pushing, check whether your bishop/rook currently has a “blocked” line toward White’s king. If that line becomes open after the pawn move—and White can’t immediately capture the uncovering piece or interpose—then the discovered check is likely.
- What’s the best way to respond if my opponent plays this discovered check?
- Prioritize king safety and legality: block if possible, capture the checking piece if it’s capturable, or move the king to a square that avoids follow-up tactics. Then evaluate whether the pawn that opened the line is now overextended and can be targeted, since the motif often relies on that pawn being temporarily untouchable.
