Arena PV comments

Is there any way to turn the PV comments saved by Arena (and Winboard?) during engine matches into actual variations in the PGN file?

Thanks for the correction. It's working beautifully.

Re: Stockfish eval output

On the topic of static evals, is there a way/program to run through a PGN to get the evaluations of the positions along the way without the engine doing any search? I came close by setting Fritz 15 to perform its blunder check with depth 1 and margin (to consider a move a blunder) of 0. Created one...

Re: Stockfish eval output

Just came across a reverse case, i.e., no material score (nor any other, for that matter), yet a big final eval. [d]8/3Q4/3K1k2/8/8/8/8/7r b - - 0 1 position fen 8/3Q4/3K1k2/8/8/8/8/7r b - - 0 1 eval Eval term | White | Black | Total | MG EG | MG EG | MG EG ----------------+-------------+-----------...

Re: CCRL Engine Authors' Tournament (will start October 1st)

Much respect to all the developers! I'll be watching this fun format with interest. RookieMonster would be smack in the middle of the last pack, but I'm not happy with how it's been blundering away promising and drawn positions. Hopefully, there will be a next time and I'll have these issues figured...

Re: CCRL Engine Authors' Tournament (will start October 1st)

Do you hold, or intend to hold, this tournament fairly regularly? (Would be interested in competing next time around.)

Transposition tables in Cray Blitz

In Computer Chess II, David E. Welsch, Boris Baczynskyj, 1985, the first chapter on Cray Blitz, had this surprising (to me) description of how it used the main transposition table: "...it first checks the transposition table to determine whether the position is stored. If so, it then checks to see w...

Hi Matthias,

Your signature caught my eye. Have you discussed this result/effect in a thread I could read?

Thanks,

Re: On-line engine blitz tourney September

An interesting system, to be sure. I had never heard of this pairing/scoring method.

Re: On-line engine blitz tourney September

Nine rounds is supposed to be enough for up to 128 players. We could consider using the MacMahon system instead of normal Swiss, however. (I would have to program this in mamer, but that seems rather trivial.) The idea here is that you start the players not with zero points, but with a number of po...
