My GOLANG_LEAGUE after 5200 games (TC=4'+2"). 32 chess engines written in Go and 11 guests (marked in green). Marked in red is GoChess-0.5.0 (NNUE)-the best chess engine written in Go. Marked in blue (GoFish, Chester & GoBit) are the last three Go engines entered in the tournament. Starting tomorrow I will let my Python_1st_League_2026 tournament progress for a few more days. It now has 20 engines, half of which are based on NNUE, DCNN or Res-Net-via .ONNX container evaluation.

My tournament PYTHON_1st_League_2026 after 383 games. The best 23 chess engines written in Python (out of the 33 I have - 8 others played in the 2nd league, 2 are not even fully functional). There are also two combos: CombiChess_10_64_ja and Py-Goratschinchess_11_64_ja, practically these cannot be included as Python engines. Don't spoil your eyes with CCRL & CEGT, only here you see them in the tournament..... .......

PYTHON_1st_League_2026 after 517 games:



Probably the fastest engine written in Python (compiled with Numba-JIT compiler):

The number of fully functional chess engines written in Python = the number of fully functional chess engines written in Go = 33. These are the ones I have. In Python I know of 2-3 new, complex engines, with NNUE evaluation, Res-Net evaluation... I haven't managed to compile them satisfactorily yet.
===============================================================================
Below is the situation in my PYTHON_1st_League_2026 tournament. There are now 24 competitors. The last one to enter is Baka Mitai-1.0.0_x64 - the only chess engine (fully functional engine) written in Python that comes from Italy. Below is some information about it.

"Baka mitai" (ばかみたい) is a Japanese phrase that translates to "I've been a fool".
