if you call you could also be checkraised by the last player, so a call does not automaticly take you to showdown

i aggre with you, folding is the answer.
if you where only two players in the pot then i would have called. but he is a real maniac if he bets in to two players with a smaller flush than yours

I aggre with Bozic.
the misstake was to bet the turn. your hand is strong but its not impossible that he have 6a 22 or 62. the only hand you can beat is basicly a bluff, so puting in your entire stack, would be a misstak according to me

good fold.
dont really see why you called the flopbet? best case you win a small hand and worst is that you loose big. if you dont fold i would prefer a raise on his flopbet. that way you can figure out if he has the jack or not. if he had aa he would probably fold to a raise

Tricky spot :)
if i was in possition i would check if he checked but in this case, its much trickier. i would probably bet pot because i still have outs with the flush. worst case he has 56xx or a5 but the flush will still get you the pot. if he has 2pair your an underdog but not that bad. he could just have floated the flopbet and might fold to a turnbet.
what did you do?
