Hi,
just for demo purpose of the workaround... Leveraging the above sample, where the H8-bug move is
instant Rhd8, I used the MessChess Cougar at level b8 and edited the position to:
Where the extra-black Knight on c1 square is the honey pot.
Here is the display result using options +rd: 1 and +rd: 2, after few secs letting the Cougar think:
After several minutes thinking, the preferred move switches to Rhd8 (so, the H8-bug move was not that a bad one, just by luck!).
Once the thinking is interrupted and the "honey pot" move has been made, one can also use the Info key to review the full PV:
Both result in: Bd6 move computed at active chess pace, instead of instant Rhd8.
Cheers,
Eric
