Title (long): I paired Stockfish 16 (Black) against Mittens AI (White), Stockfish doesn't feel that strong. It took 74 moves, and some of it doesn't make sense.
I set Stockfish to use all 20 threads on my computer, set the hash to 10000, and ponder to True.
That means Stockfish is using 100% of my CPU, gave it almost 10 gigabytes of memory to think against Mittens
on my mobile phone. I also configured it to use unlimited time on Lucas Chess. (I use intel I9 13th generation 13900H and RTX4070)
Essentially I cranked my computer to use full strength, unlimited time to defeat Mittens on mobile. I felt like something is wrong with my computer, because the engine took 74 moves, and didn't even play that good in my opinion.
Mittens (Maru) is White, Stockfish is Black.
On move 5, Stockfish (Black) traded off Whites knight, doubling the pawn on c7 and c6.
On move 8, Stockfish ignored the threat of C4 pawn taking the knight, developing the bishop.
Only on move 10, Stockfish removed the knight from the attacking pawn.
On move 11, Stockfish traded off the bishop on A6, I think moving it to b7 is better.
I think Mittens blundered by taking the knight with the C5 pawn on move 11.
Move 13, Stockfish proceeds to not take the pawn on c7 (almost promoted) with the king until move 26.
Move 47, Stockfish proceeds to trade a bishop for knight (bad trade because the board is open) by moving the pawn
Move 49 Stockfish lost a bishop, but move 50 Stockfish checked the king and won a knight (skewer)
Move 69, Stockfish moved the King instead of promoting to a queen.
Same thing move 70.
Essentially I felt like... I misconfigured the computer to play bad, a full strength engine running on a mad gaming computer for unlimited time took 74 moves to defeat Mittens engine. Maybe the RAM setup coincidentally made Stockfish weak??
