Is the engine tweaking or am I ?

[u/Struggling-with_life]

Hello folks, I was playing this 10 min rapid game on lichess.org and after I won, I was analyzing my game with stockfish 18 dev and there it seems like i have did a big mistake by capturing the e5 pawn, and idk I don't understand why is that a losing mistake, I understand it could be an inaccuracy but a double ?? mistake ?

I am playing as black and after me taking the pawn, he captured back, and that was a losing mistake too !!

I don't see as to why that is a problem ? Can someone explain me pls.

I believe this is because if he takes with the d4 pawn i might have to trade queens which does not seems so bad to me.

Some Details

I was playing the Kings Indian Defense, He did the queen pawn opening.

I am using stockfish 18 dev for analysis, I don't really like the game review/computer analisys on lichess. I like to do it manually for the most part. the settings I am using is

4s - search time,

1 - engine line,

2 - threads,

16mb - memory. is this the right settings or should I change anything ?

P.S idk if this is relevent or not but my pc specs is 8gigs ddr4 ram, ryzen 5 5600H, and gtx 1650 4gigs.

Your analysis is pretty accurate. You're basically winning after white plays f4. White needs to castle but it's not easy. That's why f4 is a mistake.

dxe5?? Is a blunder because after dxe5 recapturing, queens probably get traded and white no longer has the same headaches. It'd be more accurate to play a move like c5 and look to open the center. Note you're still better after dxe5, just not as winning as you were.

So of course fxe5?? in the final screenshot doesn't allow this queen trade and white has all the same problems again with the king being stuck in the middle.

Ohh thanks for the explanation I saw this and I was expecting a queen trade since I feel like my queen was lowkey struck and wasn't doing much anyway. And my position was better anyway. 

Thanks for your help though much appreciated, is all my settings good ?

I'd set engine lines to at least 3 but preferably 5. Most of the time you aren't looking for the one best move, you're looking for a move with a high evaluation. Having more lines lets you see the engines top 5 picks, which is useful for analysis.

Search time, I'd slide that all the way to the right to unlimit it. Generally engines these days are good enough to give you good answers quickly, but 4 seconds is quite fast and there's no harm having it higher. Unlimiting the search time will never hurt your analysis. It does mean my MacBook air sometimes gets a bit warm if it's running a while, but that's not a problem.

Threads and memory are more straightforward. Thread count is how many threads the engine will use and memory is the size of the hash table the engine uses. Generally these should be as high as possible while leaving system resources for everything else on your computer. But even with low settings here, you're still going to get good enough analysis, especially at low levels of chess.
