Thanks a lot for this tourney. Very good opposition !

In the meantime, Minic 0.30 is released with a very simple mobility term in eval => +45elo !

Minic lichess bot was lucky enough to be challenged by some lichess user this week and most notably by a multi titled candidate master (https://lichess.org/@/vovaches, https://ratings.fide.com/card.phtml?event=34105414) and won the 4 games .

https://lichess.org/wx0UFgCE/black#0 (slow positional win and a too optimistic rook exchange from white)
https://lichess.org/jWv84yBV#0 (Minic playing white is putting too much pressure near black king)
https://lichess.org/ZLfMSpHd#0 (Minic playing white is pushing a passed pawn to the win)
https://lichess.org/5LAymnvz/black#0 (almost a draw but Vladimir blunder at the end)

Minic 0.34 is out. It should be a +40 versus 0.32 mainly thanks to time management stuff ; so heading to 2500 soon...
Minic 0.34 also adds some (not activated) code to prepare endgame management and syzygy use.

[xr_a_y]

0.37 was a +35 versus 0.34
but the 0.40 is +70 versus 0.37 thanks to pruning even in end-game
Should be near 2570 now

I guess if anything ... this shows the importance of bug free code in a chess program. I think the first to show that was Fruit. While it is nice to have many features and many minor little tweaks to get the program to play "proper" chess ... bugs are the Achilles Heel of any chess program. Each additional improvement needs to come without letting any bugs creep in.

Good job on your program and I must say it is very interesting to follow up on the progress!

yes 2600 elo : http://ccrl.chessdom.com/ccrl/404/cgi/e ... _43_64-bit

Thanks a lot too CCRL members for testing.
