Crafty is very close to following rebel. I only gave it 30 seconds per move
to examine moves 16-24. Here is the part of the .can file that shows what
it would have played in the game, and how it evaluated Rebel's move if it
thought there was something better:
16. Rxd7
({11:+1.57} 16. Rxd7 Qxd7 17. fxe6 Qd8 18. exf7+ Kh8 19. Rd1
Qc7 20. Nb5 Qxh2 21. Qxe7 hxg5 $18)
16. ... Qxd7
17. fxe6
({10:+1.51} 17. fxe6 Qd6 18. exf7+ Kh8 19. Nb5 Qc5 20. Be3 Qe5

17. ... Qc7
18. Bxf6
({10:+1.40} 18. Bxf6 Bxf6 19. Nd5 Bg5+ 20. Kb1 Qc5 21. exf7+

Ke5 34. Rd2 $16)
IE thru move 24 it matched perfectly. I didn't run it further... At at longer
time limits it might change its mind, of course...
