Another small fix. (probably more to come:?)

I noticed the King was acting a bit suicidal.

Hi Jim,

I will include Pierre 1.7 JA in my ACCC 1st Edition, League Philidor.

As you can see, 'm using many of your "debugged" engines version in my round robins tournaments.

Congratulations for your work !

Hi Arnaud,

Alex Boby emailed me.

Quote:
"......The release you were working with is from 1999 and I have put in much work on it since then. I have a version 1.8 which I never released because I never finished debugging it. It has hash tables, asynchronous I/O w/ pondering, killer moves, ect... That was in 2002.

Hard to find time but I really should finish that off. ..."


Maybe he'll release 1.8 in the near future.

regards,

Jim.

There is a problem running Pierre under Arena.
The engine randomly resigns for opponent at start of new game.

Using Wb2Uci to run engine seems to cure the bug.

So I advise Arena users to run it as a Uci engine
for now.
