Re: Honey XI

Hi, Mike ! About the Fortress Detection version (Honey-FD-XI) I saw this phenomenon when I tested FD with some position : Honey-FD-XI evaluates properly when there's a fortress in the positions but it doesn't find the saving move to get in these positions.

Try Nxg2, it should be good for black ! Again that 14 ... Nxh3+ is a red herring for engines. r4rk1/1bpqbppp/p7/1p2R3/8/1B1P1N1n/PPP2PP1/R1BQ2K1 w - - 0 15 SF10 thinks 14...
