All depends on who is betting and how many players on the table. If I get raised all in with 2 pair then I fold but if you get checked raise 4xBB or whatever you feel comfortable
Most players that hit trips on the flop would raise, just from my experience.
Sometimes you gotta take bad beats like that though!
I got called all in a few days ago in a freeroll, I had AQ, hit 2 pair on the flop and he 86, im thinking what an easy pot, he hits 6 6 on the turn/river!
What can you do, just gotta take it on the chin and move on
