Peter Cafolla’s round 3 game against Jim McCarthy in the Irish Championship 1999 reached the diagrammed position at move 25.
25. ?
Black’s last move 24… Rf8-d8? turns out to be an error that allows White to develop a crushing attack. In the game, Peter missed the chance with the natural 25. Rd1?, and won after some further inaccuracies by Black.
The (engine-found!) best move here is 25. d5!. Now something like 25… a5 fails to 26. Qe6+ Kf8 27. Re1 Re8 28. d6! and it’s all over.
But how does White counter the most natural response 25… Nxd5? This part I’ll offer as an exercise.
