the reason i posted this is i think i made mistakes on the flop turn and river ...not just oh we have a boat lets go broke whatever the turn and river is
You could have played it differently but I think your always going broke.
1) Could have raised pre - your tight image if they players were watching are sure to give any raise you make respect.
2) You could have lead the flop - and you call/raise a re-raise
3) turn is cold deckaments I think its all going in no matter how you play it pre or post flop.
4) I think the only thing you can do differently on the river is flat the bet rather than raising, your only getting called with someone who has AA, QQ, AT, QT, T6 but given the way the hand played pre I think we can easily rule out AA and QQ. AT & QT are definitely possibilities. You got really unlucky mate it was just a cold deck.
Sure you could have done a few things differently but I don't see how you avoid going broke with a boat especially given the way the players had been playing.
