OliThink 5.11.9 Draw against Stockfish 17.1 in 5+2 Blitz on Lichess

Post by OliverBr »

That is something, isn't it?

OliThink 5.1.9(uci) actually won it on time, position was draw, so I consider this as draw. Lichess analysis says 100% accuracy for both engines.

Ups... there is another draw. But this time it's a UltraBullet 1/2+0.

Drawing is not that surprising with very fast time controls. Actually Stockfish lost a little bit speed with NNUE.
It's surprising here is that OliThink draws with a Knight Plus.

Analysis says that Stockf... ahem Bot1nokk made an inaccuracy with 63...Kh6 instead of 63...g5. Probably due to time issues.

And the proof for another smelling fish:

Code: Select all

[player] Bot1nokk: Hi! I'm Bot1nokk. Running Stockfish dev-20250830-731ad9bb. Good luck! Type !help for a list of commands.
And it's not that they say it in their profile. They do as they have created the engine themselves. How pathetic.
