Last night's home game. UTG and MP both have over 40 big blinds.


Preflop
UTG raises 3 big blinds.
MP calls.


Flop, turn and river
Nothing special


Showdown
UTG says he missed, asks MP if he hit. MP says no so UTG flips over AK which is the nuts for not hitting. MP then says woops or something and flips over J6. The board had both a jack and a six.


The crazy thing is I don't think MP was trying to be rude, he just wasn't paying attention.


UTG seemed to take it pretty well, he didn't seem to go on tilt or anything. What techniques do you guys use to keep your emotions under control in spots like this?
