Sometimes keeping the head stragiht is really really hard, especially when we are playing live where there a re a lot of people beside you. When playing online it's ok to have some tilt and scream to yoour neighborhood or to jump comemorating.
Once i was playing here in my city in a poker club and i was holding Kings, there there were a lot of raises and reraises before my action, then I shoved all in and everyone was folding till the last guy stopped and though for a minute or two and told me "I know you are holding a very strong hand, cause you played very few hands till now, but im gonna call", and then the guy showed his JTo, and I just kept like in silence but inside i was like ALL I EVER WANTED, but then the flop came JXX and I stopped for a while and negative thoughts began to come on my mind and everything became confusing, and on the turn another Jack came and I began to laugh a lot cause I've just lost the hand, and the river comes blank and the guy won the hand. I was still laughing cause of the ridiculous call from him but those things happen, everyone on the table was like WTF.
Summary: I ended the night eating free hot dogs from the poker club, which is nice
