Trying to get Trickier with my Draws

[frogger23]

10-25 no-limit. I've been raising several times per orbit in this full ring game. No one is ever reraising, and I generally get at least 2-3 callers. I'm sitting with 10k and half the table has me covered, with several of the big stacks playing really straightforward and unable to ever lay down second best hands. Half the table probably thinks I'm a lunatic, but the villain in this hand (who also has me covered) is a tight thinking player and we give each other lots of respect. I've never shown down a major bluff in the two days I've played with the villain. The hand in question is the only major confrontation we've had in like 20 hours of play.

I raise to $150 from middle position with A [img]/images/graemlins/spade.gif[/img]7 [img]/images/graemlins/spade.gif[/img] after one limper. Villain calls in cutoff, button calls and six of us see the flop.

Flop- K [img]/images/graemlins/diamond.gif[/img]5 [img]/images/graemlins/spade.gif[/img]2 [img]/images/graemlins/spade.gif[/img] ($900 in pot)
Several of the bad deep stacks saw this flop and I just know they won't give me credit for a flush if I hit. I bet $700 to build a pot, figuring I'm likely to get called in a couple spots, and if I hit I can really get paid off. The Villain described above flat calls my bet and everyone else folds.

Turn- 7 [img]/images/graemlins/club.gif[/img] ($2300 in pot)
When villian flat calls I think his hand is fairly transparent. I think he would raise here with a set almost all the time since so many saw the flop and there's a draw out there. He also knows that I wouldn't bet this flop unless I flopped top pair or better or a big draw against this many opponents almost ever. I don't think he would call this raise very often with suited connectors, but there is some small chance he is on a flush draw certainly. If he had 3 [img]/images/graemlins/spade.gif[/img]4 [img]/images/graemlins/spade.gif[/img] I think he would almost always raise the flop though, both to get better draws to fold and to get money in against my likely top pair type hand.

I checked to him with the intention of check raising all in. When he bets $1500 I am pretty convinced he has either AK or KQ, with AK probably being slightly more likely (he would often flat call with AK pre, very rarely with AA I think).

I push all in which amounts to a raise of $7600 into a pot of $5300. Is this burning money against the player described or a good balance against the more frequent occurence in this spot that I've got AA, a set, or AK [img]/images/graemlins/spade.gif[/img]?
