Call or fold

Went to Blackpool again yesterday and played the bounty tournament.

Unfortunately there is not much to report since I played one hand badly and that eventually lead to my demise.

The hand in question involved me limping on the button with Q3 after a couple of early limps, something I've been experimenting with lately trying to use position to my advantage.

In this hand the flop came down Qs 7s 5d. The other players all checked and I bet 700 into the pot of 1000. Everyone folded until the last player who thought for ages and then decided to call.

My thoughts here were that he didn't have much at all but thought I was stealing the pot with position. The turn was an 5s and here he checked and I felt that if I checked I might get something on the river so I checked too. The river was a 9s or something similar putting 4 spades on the board. He then bet 600 into the pot of 2400 which I felt was probably screaming for a call with a flush but I thought there was a chance he was trying to buy the pot knowing that I would need a spade to call. Rather reluctantly I called and he showed JcTs for the flush and showing that he had indeed called with nothing.
Looking back I suppose I was being greedy trying to get more chips on the turn rather than looking to take the pot down there and then.

Anyway this left me with 2200 chips as the blinds rose to 150/300 and so after there had been 3 limps on my big blind I shoved with 89 and I got 2 callers. The K82 flop lead to a check and a bet with the bettor having K6 who called with the aim of getting my bounty pre flop and succeeded.

I then went over to the £0.50/£1cash table and had an even quicker experience.

The first hand involved 3 limpers when I had AJ on the button so I raised to 5 and was called in 2 spots and then the villain pushed all in for £180+ which we all folded to.

Next I was involved with the villain in a 3 way pot where he checked called the flop with AdQd in an unraised pot. He then lead out for £10 into a pot of £20 when a second diamond came on the turn and then he bet £6 into the £50 pot on the river when the flush came and reraised when raised holding the nuts.

A few hands later he raised to £5 again from the small blind and I called with 2 of the limpers holding As Jh in the big blind. Now when he raised he was shaking like he did when he bet the AQ on the turn before and I had him down as having a big hand here and called with the aim of stacking him on the right sort of flop.

The flop came down AhQhTh and he went all in for £200. I had £112 in front of me and I've got the ace, straight draw, second nut flush draw and the Kh would give me the royal flush.

This put me in a really difficult spot and after a think I decided that I couldn't fold.

The question is should I have?

What hands would he do this with?

I felt that KK holding the Kh was a fairly good chance as was AK, AQ and AT but AQ and AT less likely given his percieved strenght pre flop.

I didn't think a flush was at all possible.

So I felt I was probably behind but with the best possible draw and no chance of drawing dead.

AK and the Kh was my worst case scenario.

Any opinions would be welcome here.

Needless to say I left straight after although, given the overbetting in the short space of time I was there I regretted that 10 before I even got to the door.
