Why convert to Rook?

I made a move and the computer showed a series of better moves that included this pawn promoting to a rook ... how does promoting to anything other than Q or Knight make sense?

Any insight is appreciated. Thanks

Sometimes it's stalemate if you promote to a queen. So you have to promote pawn to other piece.

Hi,

I assume that is from the game you played yesterday. I got it to that position and the evaluation bar definitely prefers a queen. Maybe promoting to a rook was better than a worse move but promoting to a queen is definitely better!

There are a number of occassions when under promotion is worth while, a rook can avoid a stalemate.

It's a bug. Those "example lines" in Game Analysis are clearly bugged, but nobody cares enough to fix it.

I'm just going to be honest, promoting to a knight or bishop also is completely winning

When the chess.com computer is promoting a pawn and expects the promoted piece to be immediately captured, it will very often promote to a rook (occasionally a bishop) instead of a queen. I wonder if it feels that it "loses less material" that way? My students and I have seen this enough times that it's a running joke for us.

Why is there no option to promote a pawn to a reversed pawn that then goes the other way

If you look at the example position carefully, the promoted piece isn't going to get captured because black has no piece to capture it.

It's a bug.

which is more impactful among camel and horse?

to avoid stalemate

somestimes you have to underpromote to avoid stalemate

Or a fire engine maybe.

Thanks for all responses ... the stalemate issue is a good point but doesn't apply here so I guess the "bug" diagnosis must be correct. Thanks again.

I have an idea. Make it so that only the pawns in front of the King and Queen can promote to a queen, the other 6 pawns can only become Knights, Bishops or Rooks

So that there can be a reason for Rook and Bishop promotion.

Promoting to a rook minimizes the chances of a stalemate. I've drawn against queen PAIRS plus bishops and even a rook once by playing hide and seek in the center or around enemy pawns.

Promoting to a rook makes for a slower win, but if that's all you need to finish a game it's good practice and sends a signal to your opponent that "this is all I need to mate you".

If a position is complicated with potential counterplay, I'll go for the power piece. I just played a game where I promoted to a knight just for the check tempo last week
