It's really hard sometimes. What helps me is that no matter what the beat is, I have been on the other side before.
So, a guy who should not have been in the hand got lucky and hit gold with 2 rags.
So have I.
A guy sucks out and kills me when I have had the nuts on the flop.
So have I.
A guy bluffs me and shows it. And It was a pot I really could not afford to lose and will probably cost me the game.
So have I.
No matter what the beat, you always remember the beat and forget that chances are you have done the exact same thing to someone!
I just watched a WPT paris event. One guy raised UTG w J-2 as a steal. The short stack w ace-rag shoved. The guy w J-2 could not call, it was 1/2 his stack if he lost. Guess what? Not only did call with J-2, he spiked a deuce on the river and took out the other guy. It had to hurt. Everyone at the table knew it was BS. The announcers knew it was BS. Even Mike Sexton, who was playing, his job as annoncer filled in by Phil Hellmuth, stopped over to the booth and said "I am glad I am not up here, because I would have no idea what to say about that last hand". Needless to say what Phil said about it.
You know what the guy who lost did? Shrugged it off, looked like a classy guy and said not one word about this horrible beat that ended his game. He might have later put a hole in a wall, but I doubt it. In the end, what can you do? Getting mad will weaken you.
So just laugh it off. Realize you have done it before. Know that getting mad will only weaken the rest of your game. And remember class acts like Doyle Brunson and others who take it all in stride. :willy:
