Got Dicked in the Omaha Nutz

I got destroyed Monday night. Mostly my fault. I made a big bet into a multiway raised pot with a open end straight draw. I got reraised allin by a Jack high flush draw. I called. It wasnt a smart call. The Jack high held up. The cash game started as straight Omaha. I did ok. I got up like $400. Once again I broke Bob when he didnt hit any outs. Of course he cant miss forever and later he would double through me. I went to the felt when I flopped the nut flush draw in a raised pot. The flop put out a possible straight and a couple people checked to me and the original raiser was to act behind me. I was hoping he had AA. Nope. He had a big ole pair of 9s with which he poted preflop. So lucky for me he flopped top set and called figuring he was behind. Well once Bob was getting 2 to 1 he called too. I didnt improve and the set of nines held up on a board where its really hard not to have a straight. I have no clue what Bob was drawing to. Probably a worse flush. At some point we had started to play half n half and I think I played every pot if I had any playable hand. I rebought for $400 and was just playing passive fit or fold poker. My last hand I flopped a set and put about $90 in by the time the river made a straight possible and the out of position floater bets $100 into me. I shoulda called but I didnt. I definitely got bluffed. I cashed out immediately. I knew if I stayed I would lose that $300 and maybe another $800 after that. I had planned to play till morning but ended up leaving at 12:30am. Oh well. At least I didnt try a desperate run at recooping my $500 loss. I went home and did some review and reading and had to admit that Im still not playhing optimal omaha and need to study a lot more. If I follow through with that then maybe that ass whipping will end up being profittable. I should have some posts soon from playing in Phoenix AZ. I understand they dont have NL but have a $250 max bet spread limit game. Shouldnt play too different and may actually be better for me because I get too conservative when I get up a lot because I dont want a big stack maniac putting me to an $700 decision.
