24. Bxc5=.

24... Nf4 25. Qc1?

25. Bxc5.

25... Nc3

A thunderbolt, based on the theme of forks on e2, for example 26. Bxc3? Rxe1+ 27. Nxe1 Ne2+.

Unfortunately, there is a flaw: White can escape via 26. Qxf4! Rxe1+ 27. Rxe1 Rxe1+ 28. Kh2, when, since both rook and knight are en prise, Black has nothing better than 28... Ne2 29. Qd2 Nxd4 30. Nxe1 Nxc2 31. Qxc2, with only a minimal advantage for Black.

Better was the more pprosaic 25... Ng5, or the engine's choice 25... Nxh3+! 26. gxh3 Ng5.

26. Rxe7?

White fails to find the chance. Now it's all over.

26... Qxe7 27. Qb2 Nce2+ 28. Kf1 Ng3+ 29. Kg1 Nge2+ 30. Kf1 Nxd4 31. Re1 Nfe2
