5k six handed report

This was one of those events where nothing went right, and I really didn't get any cards to work with. My stack swayed between 7500 and 12500 for about the 3.5 hours that I managed to stay alive. My starting table was pretty tough, with Bill Gazes, Sam Grizzle, and the good internet player Ahh_Snap (who is a very nice guy by the way). The table was actually pretty boring and we didn't play a big pot or lose a person the whole time until we broke. I did manage to get Ahh_Snap to lay down an overpair on a 522 board in a 4 way raised pot. I had been playing tight (because my cards were awful) so I figured it was time to make a move and I felt I could represent something like A2 that called in the big blind due to the immense pot odds the other callers gave me. I then got moved to a table with Darrell "Gigabet" Dicken. After about an orbit, he raised UTG and I was only the caller with 77. He checked to me and I bet out on the 6 high flop. He called and I wasn't exactly sure what to put him on. The turn came another low card and I wanted to check to maybe induce a bluff from him on the river and to keep the pot under control. The river came an Ace and he thought for awhile and the bet out about 2/5 pot. At first I thought this was an awful card but after thinking it through I didn't think he was the type of player that floated out of position with a big Ace, so I was now more concerned about a higher pair than mine. Then I realized that a higher pair would never give a free turn or river card, so I felt he had to be bluffing a missed draw or complete air a good portion of the time here. I made the call and he instantly mucked and then scolded himself for not check/folding as he couldn't possibly represent an Ace there. That was a confidence booster and was also the hand the put me at my pinnacle. I lost a couple thousand chips over the next few orbits to squeezes and a big stack who kept floating in on me in position. My final hand came when I had 10k in chips and was in the big blind with Q9. It folded to the button who made it 700 (blinds were 100/200 with 25 ante) and I made it 2300 leaving me about 7.5k behind. He called my raise, which I didn't really like, but then the flop came 789 and I knew there was no getting away from the hand now. I bet out 3600 and he pushed me in and I called. He turned over 10Js for the nuts, leaving me basically dead to runners which didn't come. In my opinion, this an awful play for him to make with these stack sizes. He has to know I just put in 1/4 of my stack and that just about every flop I am going to make a bet that commits myself to the hand. When a player is in this situation, Jack high doesn't play very well because it's essentially like calling an all in with Jack high. Now if I had a deeper stack, the play is perfectly fine because he has position and a hand that can create a lot of opportunities. Oh well, nothing you can do. Next time I will just make sure my opponent doesn't flop the nuts on my speculative steals...
