How do I stop laughing out loud when I am winning?

So each time I start winning, I always start smiling or laughing and I don't like doing that, but for some reason I can't stop, I try so hard and I just can't stop laughing. It only happens OTB.

Imagine your opponent behaiving the same way.

I agree with @White_Queen_1990 :)

Experience (imho). This used to be a slight problem, and now I'm much better at holding my expressions during the game.

Well, you should try out this in chessboxing!

We should respect our opponents:))))

Yes!! Respect is very important!! :))

I rage when I lose lmao
