From this position, White is up a bishop and a knight for three pawns. Black's remaining Knight is pinned to his Queen, and he will be unable to protect the Knight without sacrificing a certain amount of King safety (P-KB3). After, for example, 24. ... P-KB3, 25. N-KB6 ..., 26. QxKR5, Black's position begins to look awfully bleak. There's probably a refutation to what I just suggested- I only had a couple of minutes to glance- but that's what I saw on my own.
Crafty (a chess engine) saw this continuation (which I don't have time to translate to descriptive notation. It seems to show a similar idea to what I saw.)
