Hi,
I am beginner, but I know that pawns move forward, and diagonal when taking over another piece. However, it happened to me twice the opposite player (computer) takes my piece with a pawn moving sideways ( the same as the king, Queen, or rook would do), is that even possible ?

It's a legal move called en passant.

En Passant is probably what you are looking for, but there is also a chess variant where this movement is allowed: https://www.chess.com/variants/sideways-pawns

Yes, in 1973 Dutch Grandmaster Max Euwe created the infamous “Euwe Rule”. The rule stated that any game with a combined time of less that 15 minutes can be played with pawns moving sideways, backwards, and off the board. So, I’m guessing that the time was less than 15 minutes which would have allowed the pawns to be moved sideways. This rule applies for over the board chess as well. Have a nice day and good luck with your chess endeavors!

How bout the Euwe rule addition? He made a revision in the following year, in 1974, where in addition to this solid rule, he stated that in online chess, the Euwe rule would apply to any games without a classical time limit. As computers take up a fixed amount of time, logically, the rule would state that any computer games were non-classical, and therefore had the Euwe rule implemented. Hope this cleared up your problem!

(P.S. Humans cannot play this rule as their time limit is absolute, and therefore defies one of the main constructs of the Euwe rule.)
