"DarkThought" agrees on Bxc6 (score = +1.23) but simply e6 may be equally good. Actually, I would drop the position. >No. 82 (exf6): > >Not found in 20 seconds, but turns up later. > >Recommend: No change.

"DarkThought" likes both Bf4 and Nc6 and finally locks on Nc6 in iteration #12 with a score of +1.13. But as Bf4 and maybe also Nxe6 do not seem to be far behind I would drop this position, too. >No. 96 (Qe8+): > >This one's correct and is mate in 5, but so is Nf6+ with a different >move order. > >Recommend: Add Nf6+ as side solution.
