TCB says I'm wrong, it agreed with CM for a while about Bxd7+, but then the last
pv before I stopped it looked very cool, eval = 29 1. Ne5 bxc3 2. Nxd7 Nxd7 3.
Qh5+ Ke7 4. Rd1 Ra7 5. e4 h6 6. bxc3 Rb7 7. Bg5+ hxg5 8. Qxh8 e5 9. Bxd7 Rxd7
10. Rxd7+ I liked that one a lot because there's no way I could have thought of
that.
