Glad to announce LA timed is here !
This version WON to ECE 6+8 this morning in a back-and-forth game, with some blunder from both sides, but it did it !

Except is an unknown bug is found in the following days, this version will replace the main one on both the studio and the current olympic for which France is the next team to play btw… so can you all test it out ?

Congrats! Beating ECE 6+8 is no small achievement
Haha, you would know…

Jokes aside, LA’s improvement has been incredible over less than 2 months. Congrats! Is Element falling off?


no
for sure no lmao, that one bushop just got horizon effected for 20+ moves and LA got lucky I guess

v1.54 LA is out ( the 1.53 stood for 2 minutes lmao ) !

There is now a partial 2 fold detection, preventing LA to play 2 times the same move in the same position if he thinks it has an higher than 50 centipawns advantage. There is also a huge improvement in time management, helping playing better in quick-paced games like blitz ones.
Example game where LA wins against a 1500 FIDE friend of mine in 4+2 time control : https://lichess.org/PyqeI0yj

As a quick side note, it now converts the endgame who ended in a 3-fold against ECE 6+8 yesterday

I forgot this forum, lol, you can divide the eval by 2 if itns the 2nd rime and set the eval to 0 if itns the 3rd time, it's better

CONGRATULATIONS TO WHITE DOVE (P2), for its first win against GoK Classic (Medium, white) on TW and standard chess, playing a near-perfect game (one mistake in final endgame stage when everything was over), 97% vs. 93%. After many close-to-win matches, this victory indeed is well deserved! It also uncovered a GoK Classic bug, that led it to accept a positional disadvantageous RBP-vs-Q trade:

https://lichess.org/rHv9rnH8#126

The rematch, same opening, updated GoK Classic (white), 97% vs. 90% accuracy:

GoK Classic has moved to its previous dev project location: https://scratch.mit.edu/projects/828094886/

I think so too, and what can you do against an opponent running at 97% accuracy (or actually 100% until move 46).
