i call since i was in BB and both player were a bit loose and button raise doesnt mean much in the sense might be an isolation raise.

there it was, maybe the mistake.
think i should of 3 bet the flop to really see if i was ahead.
now when i just called, im being(maybe) shut down for a free cards.
If i 3 bet the flop, it would of drop probably the utg player?(since i know the results of hands now) and showing me where i was vs the vilain.
Im asking if usually ,when u bet out,a 3-bet would be a better play instead of just calling?
lot of players would of just c/c or c/r but i feel betting out helps me win more pots on futur hands right there on the flop,if im getting raise and i improve on turn i always gain lot of bets by c/r them on the turn.
i must add, after a couple of time i succeed with this play,
when i bet in early position i get a lot of free cards when i have a medium strengh hands,keep them off balance a bit.
it might be a bit expensive but i guess the price paid is refund by getting free cards when early position in futur hands to see a free river when im not strong enough to c/c or c.r?

i would probably called the river bet (since the button didnt showed strengh after flop) but when vilain raised i couldnt beat anything after i guess...
i wish i would of post the results hands because it showed how i couldnt do better to prevent what happened since i was oop?? [img]/images/graemlins/frown.gif[/img]
