23 ... Nec6 24 Bg6

(24 Nxg5? looks attractive, but Black should hold after e.g. 24 ... hxg5 25 Qxg5+ Be7 26 Qg4 Nxd4 27 Bxf4 Nb5 28 Bxb5 axb5 etc. Too many White Pawns are loose at this point - if h5 was guarded by other than the Q this would indeed be quite good as Black's pieces are not well situated to stop the passed pawns, and White would have a full three pawns for the knight after 26 Qxf4. But in this line, 26 Qxf4 Rxh5, and Black actually stands a little better for once according to Junior 9)

24 ... Re7 25 Nc3 Bg7

Or some other move, such as Rg8. The point is that nothing Black can do is of real significance here. The position conjures up images of complete docility and submission; White has all the time in the world to come up with the means of execution. The following is only one of many means -

26 Na4 Rf8 27 Nc5 Bc8 (27 ... Be8 28 Nxe6+ and mate in a few moves) 28 Rxe7 Kxe7 29 Nxg5! (Now this is murderous) Nxd4

Black could not accept the sac; 29 ... hxg5 30 Qxg5+ Rf6 (Bf6 31 exf6+ Rxf6 32 h6 and now that Black's R is pinned the P must queen) 31 h6 Bh8 32 Bh5 and Black is done. 32 Ne4 is also more than sufficient, but Bh5 leads to a forced mate in 9 according to Junior.

30 Nh7! Bxe5 (Black cannot move his Rook, as mate follows by Qh4+) 31 Nd3!

Stronger than taking the Rook, and now Black can no longer hold both black diagonals. Black has three choices here, all of them failures:

a) 31 ... Rf5 32 Bxf5 Nxf5 33 Nxe5;
b) 31 ... Bd6 32 Qh4+ Kd7 33 Nxf8+ etc. (forced mate according to Junior)

c) 31 ... Bf6 32 Nxf6! (even stronger than taking the R, or even the check at b4) Nbc6 (Desperate; it's notable that only now does Black get to get this Knight out of jail. If 32 ... Kxf6 he is mated by checks at h4, e7, and h7; if 32 ... Rxf6 33 Bb4+ also leads to mate) 33 Nh7! Rf5 (he must do something about Qh4+; e.g. 33 ... Rh8 34 Qh4+ mates in 7) 34 Bxf5 Nxf5 35 Qg8! (threatening mate either by 36 Qf8+ and 37 Nc5#, or by 36 Bb4+ etc.) Kd7 (if Bd7, the Queen is simply captured, after which Black will still succumb to mate) 36 Qf8! (threatens mate in one!) Nfe7 37 Nf6+ Kd6 38 Ne8+ Kd7 39 Nc5+ Kd8 40 Nd6 (or any other Knight's move) mate. Or if here 36 ... Nce7 37 Nf6+ Kd6 (Kc6 38 Qe8+ mates next) 38 Qd8+ Kc6 and now White mates in two by either Qe8+ or Qc7+.
