what happens if you castle the wrong side


This has nothing to do with castling. You got horse happy. 7...Ng6 not good. There's nowhere for that knight to go. Loss of tempo too.
Castling kingside certainly didn't help.

There is nothing wrong with castling kingside.
Of course not. I do it all the time. I meant that in the OP's game specifically, castling kingside wasn't a great idea.
