ShashChess

Thanks for the engine. I especially like the new MCTS Settings. I am currently playing with the engine at today's InfinityChess tournament (after 12 Rounds +1 with MCTS = Single). Unfortunately the engine has a timing problem (Stockfish too). The new tournament level on InfinityChess is now 5m + 3s. Even though I had set the slow mover to 145, the engine moved the first calculated move (Move 5) after 5s. That is to fast. The clock showed 5m + 13s. I can't play like that.

Concurrent experience is for cutechess user using concurrency.
No: the merge mode is the same, but the file names convention is the following one:
experience.bin
experience0.bin
experience1.bin
...

Not only does merging of experience- files not work with ShashChess 17 sse41-popcnt at Fritz GUI and Windows7x64 Pro, learning at backward analysis nor at game playing doesn't work neither. An experience.bin is created but it doesn't get any bigger than 1Kb, not at automatic Backward of 60 games nor at 8 games engine- engine playing.
With BrainLearnDGV 1.0 it grows slowly but steadily. 5Kb after Backward of 60 games, 1 more after 2 games engine- engine. And merging of experience files works with BrainLearn (sse41-popcnt compile too) as well regards

To merge experience files it's better to use BrainLearn.
The experience file increases its size only when standard or self learning option is selected.

Thanks, I know so regards

Dear Andrea! I noticed that ShashChess creates a learning file called experience.bin. But if I switch on MCTS (the setting Single) then experience.bin becomes experience_new.bin. When MCTS is switched off again, the learning file is called experience.bin again. Why this?

[Eduard]

The engine plays impressive and very interesting. I played tournaments on PlayChess and InfinityChess for 2 days. MCTS was set for single. Yesterday on Infinity +1 and 5th place and in the Bullet on PlayChess 3rd place. Today on InfinityChess also +1 and 3rd place, tied with the winner. With 23.000 kns (start position) that is a very good result.

ShashChess 17.1
Solved an important bug on the search for Shashin theory.
The engine now is a lot stronger.

An extraordinary result also on hard positions:

What means eg. 1q1r3k/3P1pp1/ppBR1n1p/4Q2P/P4P2/8/5PK1/8 w - - bm Rxf6 :
the numbers 64 and 88 in your spreadsheet ?

Rf6 (64) 1 Rf6 (88)

For other positions there are also 100 and 100 for both engines displayed, so it whould not sec. ?
