Blackmar Diemer Gambit Accepted Teichmann Defense Deflection in Chess

In the Blackmar-Diemer Gambit Accepted (Teichmann Defense), “deflection” is the tactical idea where Black is lured into a specific capture or placement that pulls a key defender away from an important square. A defining feature is that after the gambit is accepted, White’s pieces aim at central and kingside targets while Black’s resources are temporarily misaligned. The motif is about forcing the opponent to respond in a way that creates a short-lived but decisive advantage in tempo or piece coordination.
