The lattergame was the only loss by Byrne in Leningrad. It demonstrates the superb playneeded by Korchnoi to beat him.Diagram 1The following position occurred afterTaimanov (black) grabbed Byrne’s kingpawn with his rook and then retreatedhis knight (then at QN5) to QB3 whenByrne chased it with P-QB3. Byrne hasthe surprise move 26, N-QB5. If Taimanov had moved his attacked rook, hewould have lost the QRP and rook (atNl) for the white knight.
