Up Topic The Rybka Lounge / Computer Chess / Fizbo 1.9 unable to deliver mate!
- By Peter Grayson (****) [us] Date 2017-11-09 18:37
The following game was played in a 6 threads + 4Gb hash per engine, 40 moves in 5 minutes repeating tournament I am currently running. Fizbo 1.9 played the right moves up until move 91 but was unable to deliver mate playing 91.Qh1+ instead of 91.Rxh6#. After 97.Rxh6, the Fritz GUI 14 took over to play out the 5-man TB win.

In other games the Fizbo 1.9 engine has clearly indicated the moves to mate but here for some reason it never indicated mate!?
