Hello everyone,

CrazyAra 0.4.0 is online for you service again from Feburary 12, 21:00 hrs to Feburary 13, 21:00 hrs (Central European Time).

Feel free to challenge the bot in blitz-time or rapid time control format in the Crazyhouse variant (casual or rated).
@CrazyAra

CrazyAra is a neural network based Crazyhouse engine which was trained supervised on the lichess.org database.
More details can be found here:
lichess.org/forum/general-chess-discussion/crazyhouse-ai-crazyara?page=1
github.com/QueensGambit/CrazyAra

v0.4.1 uses a new technique in the mcts search by taking future q-values of the search paths into account. It should be slightly stronger than v0.3.1 which played @JannLee.

Score of CrazyAra-Dev-0.4.0 vs CrazyAra-0.3.1: 18 - 12 - 0 [0.600]
Elo difference: 70.44 +/- 133.

I wish you good luck in your games,

Hey,

as a bonus in the last hour you can try playing a network which was trained further on 120k SF self played games (CrazyAraFish):
github.com/QueensGambit/CrazyAra/wiki/Stockfish-10:-Crazyhouse-Self-Play

The network should be around 100-300 elo stronger than the current one.
It will accept non-rated games in all time controls.

Have fun,

~ IQ_QI / QueensGambit

Thanks for developing & temporarily hosting this excellent engine!

@Toadofsky Thank you as well for working on the amazing multi-variant fork of Stockfish and providing it to lichess.org for analysis.

I also enjoyed your last stream. :)
