Review of computer games feature

I just joined chess.com, to wake up my chess after many years of not playing.  I've been methodically working my way down the list of computer opponents for the last few days, and I'm in the middle of tackling the ones supposedly rated 1600....

I've been pushing the Review button after each game to learn from my mistakes and inaccuracies, and I've found to my sorrow it can't be trusted.  Yesterday it flagged a queen move I made as a mistake, that resulted in checkmating my computer opponent two moves later.  It said I missed an opportunity to move my knight instead, and threaten a pawn at the other end of the board.

This morning I moved a pawn to support my queen in a checkmate in three, and the Review flagged the pawn move as a mistake.  It said I should have moved a different pawn (again, at the other end of the board), to attack a knight.

Sometimes after I decide what move to make, I'll click the hints button to see if it agrees with me.  Now and then, I can see no reason for the move it recommends.  At first I thought I must be too dumb to see what it's up to, but I'm starting to realize that occasionally it honestly doesn't make sense.

What is suggested is going to come down to the configured review depth, but in most situations, the moves suggested will be the best moves in the position. Without concrete examples, it's hard to say if you may have missed what the engine finds best or if there's something more going on in the position.

Obviously it isn't 'necessary;' few things are. But it's intended to be helpful....

Trust me on this: in both situations I cited, I was within two or three obvious moves of checkmating my opponent. Each time the Review claimed my move was a 'mistake', and suggested I should instead have threatened a completely irrelevant piece at the other end of the board.

It is absolutely bizarre to talk about those games in these vague terms, instead of showing the games. It is possible (1%) that you are right, but I would not bet on it.

No. What's bizarre is that anyone would question my account of what happened.

It honestly never occurred to me I should save throwaway practice games against computer opponents, so I could defend myself against being called a liar. But I guess trolls are everywhere...

Please share the games and moves where it had poor move classifications.

Unfortunately, without some way to recreate a potential issue, there's no way to determine if there may be a bug or there is some other explanation.

--I haven't been saving practice games against computer opponents. So unless there's a history generated that I can scroll through to retrieve them, it's a dead issue.

It didn't occur to me there might be a bug; I just assumed the Review engine has its limitations. For what it's worth, I've been playing a dozen or more games a day this week to get the kinks out of my brain after thirty years, and the two cases I cited were the only ones I've noticed - because they were so blatantly obvious. I suppose there may have been others, that slipped by me.

Both times I was driving a king into a dead end and pinning him against his own pawns, using my queen and one supporting piece.

First of all, previously you claimed that you analyzed the game. That means that it is stored on your page. If you remember which bot was your opponent i9n both cases, you can find it. Nobody else can.

Second, I am not calling you a liar. I just expressed the feeling that you are probably wrong, and your "winning move" was not good.

theres supposed to be a show moves button underneath both the actual moves and the reccomended moves, it'll show what should happen. the next time you see this kind of thing try checking the show moves and see if that helps.

Yeah, whatever. Just keep on trolling, I won't be bothering you.

You wrote this while I was editing my last post. I guarandamntee I'm not the troll here....
