Re: .10/.25 Omaha/8 of HORSE game - Flopped Nut Straight w/ TP
I get the general idea that you overvalue high hands- Your hand should be folded pre, rundown hands are bad in O8 once you get a few cards below T involved. Also I don't agree with your reasoning that he would have 3-bet QQJT preflop, unless he is a maniac O8 players don't 3-bet hands like that.
Normally it wouldn't be good to put in 90-something raises with a weakish redraw like this, I would usually stop a lot sooner than that personally- but if you know for a fact that he plays every JTXX like this, it's OK. Against a solid player, it would be very bad. I wouldn't be worried about the rake so much as being up against a straight+set which has you crushed.
