I really don't know why I do this, seriously I know my opponent has a big hand, I flopped gin yet my brain forces my right hand to click check rather than leading out. I know it is the wrong play but I do it anyway.

Example:
8 players NL 50
I have UTG+1 with about 75$ and raise it to 2$, folded to a serious donk on the CO who has me covered, who min raises to 3.50$. Folded back to me, who opts to call rather than re-pop. Now against this donk who is 60/5/1, my notes are that he can't fold TP type hands nor does he make people pay much with his big hands. His Min-raise had to be AA, KK, QQ or at worst AK.

Flop comes out

I check here, dispite the fact I knew I should bet, villian then bets 1$ into an 8$ pot. So I figure I better just call here, despite the fact my hand will become more obvious.

Turn

Here I toss out a weakish lead again probably a mistake I bet 7$ into a 10$ pot, he then min-raises me to 14$ at which point I realized he was mine, no matter what I do.

Anyway I know I got a good result from the hand, however I still feel I made alot of mistakes especially playing the flop like a retard. I actually feel I let a player that only had 46 chromosomes get away from the hand too cheaply, what are your guys approaches against better players in these type of spots?

yea id say lead out on flop, you know hes probably going to stick with you anyway, so try and get that money in from the start for the most possible
