Test of Young Master 1.2 x64

Post by taychoe »

GUI: Arena 3.5.1
Time Control: 2.5 min + 2.5 sec increment (equivalent to 2 min + 2 sec on an i7-3770 machine)
Hash: 256 Mb if possible
Threads: 1
Tablebase: None for engines.
Ponder: off
Book: Engines use their own book if they have one. Otherwise, a 5-move Arena book is provided.
Maximum number of moves: 160

Adjudication:
- Arena is only allowed to adjudicate tablebase draws, draws by repetition, draws by 50-move rule,
and draws by maximum number of moves.
- Arena is not allowed to adjudicate games based on scores.
- An engine can only win via checkmate, time forfeit, or illegal move.
- Resignation is disabled, if possible

The bulk of the tournament was completed weeks ago. I only added Young Master 1.2 x64 to see how it fares against other C engines in the 2450 to 2560 range.

Code: Select all

Thank you for testing my engine!
Also, thank you even more for somehow getting it compiled on Windows. :D
It's quite funny that I didn't know about this until randomly finding this forum page while crawling through talkchess...

As for the embarassing example game, it seems I might need some mockup evaluation in won endgames after all, I thought I this ages ago with mate distance pruning.
