My Crafty 17.14 (downloaded from Bob's ftp long ago) also misevaluates (at least) one possible resulting KPK (after 8.cxb6 in the line we have discussed) as lost instead of draw. It gives only -3 score, though. Of course this is no big deal, and it is a non issue with TBs, and of course one just might want to accept, that some KPK are evakuated wrong. For a small while, I get Kg4? instead of cxb6, which does look a bit strange. 13 0.53 -7.00 8. cxb6+ Kxb6 9. Kg4 Ka5 10. Kxh4 Kxa4 11. Kg3 Kb3 12. Kf4 Kc3 13. Ke5 Kc4 14. Kd6 Kxd4 15.

Kc4 Searching for 2.h3 and 3.g3 might be good test positions (for engines without TBs?). Cheers, Dieter
