Definitely not Mate in 14

Post by AdminX »

Not sure if it is the current Chessbase 14 update or Houdini, but this is definitely not mate in 14!

What is the position?
Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

Sorry for the delay Dan, I had to wait for Tactical Analysis to complete before I could grab the FEN.

[d]3r4/3bkp2/8/R3p2p/4Pn2/1P3PK1/8/8 b - - 0 41

The point being the mate shown in a mate in 26.

I will try to verify with Chest

Sounds like a bug of some kind. What GUI were you using?
