Suddenly, the knight on b4 is pinned. Caleb ponders for a few minutes belts out...} d4 $1 {While the engine still likes white, this move has a lot of psychological venom. White may have thought he was winning a piece, but this move totally disrupts white's forces. It also frees black's knights for d5 and the bishop on the a8-h1 diagonal.} 14. cxb4 $4 {White panicked.
