My last experience - last week I was playing in casino 20$ rebuy tourney....6 players were getting paid and I was short stack sitting in 6th place after 4 hrs of play knowing that I am at least getting 165$ back for my buy in and add on which is not to bad. So anyway, I am in small blind have 12k chips left, blinds are 4k and 8 k. Everybody calls, I have AQ suited... what the heck I will put in 4k more. Flop comes KQ3 everybody checks. Turn comes in Q, I have 4k chips left...sure I put my last chips in without hesitation. Dude with big stack calls and shows QK and I am out after river in my 6th place. Now small detail what I did not mention was that girl in BB had 1k chips left and got kicked out very next hand winning 65$ more than me...Had I not played that freaking AQ and just folded I would be 65$ richer or maybe something crazy would happened and I may have ended up even higher since table was dominated by one dude with super big stack and rest was kind of short or medium at best.
Moral of the story, sometimes it pays of to fold good hands no matter how tempting they are to play when other people are about to get kicked out. Poker requires concentration and attention to small details which is not easy to do after playing for 4-5 hrs or so. I just can imagine what kind of headaches people go through multi day tournaments, just crazy how disciplined you need to be to be successful.
