Sveshnikov - Stockfish goes nuts!

Stockfish.

Initially it was wrong both on move 27 and 28. But once I let it run on move 29, it then correctly evaluated the earlier positions and suggests 28. Bd3
I don't understand the "showing" effect, when you make a move then the engine suddenly "sees" the continuation when run on the initial position.

Now Fish = ez win)
Bro really cool

Wow I've not seen SF this confused since the SF8 days when it thought playing Qh8 against A0 was a good idea.

This is because Stockfish is able to memorize positions it has previously looked at. (https://chess.stackexchange.com/questions/33161/do-chess-engines-hold-their-search-tree-in-memory)

True.

Yeah this is the one I had in mind. Here's a Lichess link:

after Qd3 my stockfish 16.1 immediately recognizes that Black wins - 2.5
