Englund Gambit Complex Discovered Check in Chess

The englund gambit complex discovered check is a tactical motif that can arise from the Englund Gambit, where Black sacrifices material and then uses a discovered check to swing the game. The defining feature is that a piece (often a bishop or rook line) is revealed to give check only after an intervening move or capture changes the line. In many lines, the “complex” character comes from forcing moves that set up the discovered check while the opponent is still dealing with the sacrifice.
