Hand 1: my initial reaction is to say call. I would look at your percieved image of villian (mega tilt) and how he percieves you (i want to beat this mother ******!!!). It could easily be an overbet with 7-7+ or a big FD. I think mega tilt would check his monsters, in the hopes of keeping action in, not forcing it out (assuming most mega tilters usually don't think at multiple levels).

Hand 2: this one is kind of hard, but i imagine if he has A-9/10-9 and you call a big turn bet, he is checking his set or leading out again with a higher flush. Though looking at this calling the turn makes it very difficult to surrender this hand on the river, regardless of his action. I might go for a minraise here and see if he shoves/folds/calls. If he calls/folds, you are good i think. And if he shoves you are beat most of the time, i think (especially if he was being serious when he said he didn't want to play against you). $50 extra on the turn is cheaper than $65-70 on the river.

And trips probably isn't going to pay you much more on the river, besides the smallest of value bets on the river (not worth it to let him try to draw to a FH/ higher flush). Though Kc-9x and Ac-9x would likely shove the turn and you have an edge over those hands making it profitable to call ((7 clubs+11 FH outs)x ~2= 36% at best), that is the only scenario i can think of where calling a turn shove has you ahead or even drawing live.

Question: how often would this board tempt a player to bluff (suspecting opponent is afraid of clubs because of his flop bet)?
