Poker player tournament - Brighton

This tournament was sponsored by poker player magazine.
100 runners paying £50 each with the winner getting a gukpt seat as well as £1500.
We started with 5000 chips with blinds 25/50
Early on I called a raise with ak and the flop was a67 all diamonds. I raised a bet of 300 to 900 and he called. Turn is a rag but I smell a rat so I check behind. River another rag and when he checks I do too and he shows a flopped flush.
I win some chips later when I reraise a flop of q75 with 2 spades when holding kqd. I think he probably had aq because he said he thought I had a big flush draw.
Not much happens then the fickle poker gods strike.
First I have 62 on the bb when the blinds are 150/300. The flop is T96 after 3 limps. All check. Turn is a 6. I check ready to raise but no takers. River is A so this time I am sure someone will bet. Sure enough someone bets 800 and calls my extra 1000. Sweet.
Next hand I am sb. I have 57h so I call 3 limpers. Flop is a beautiful 77A so I check. No action. Turn is Q surely someone will bet. I check BB bets 400 and is raised to 1500. There are 2 diamonds now so I think the raiser probably has the Ad. Clearly the bb had Q so he folds. Raiser calls my all in and shows 78. So looks like a split until he catches an 8 on the river.
Now I have 600 chips but the very next hand I get as and I double through qq.
After the break blinds are 200/400 so I am looking to go all in. I get T9h in mid position so I am in. There is a call all in from someone with 600 and 2 further callers. The bb is getting good value too so we end up 5 way. Flop is 236 turn 9 so when my nemesis bets and the others fold I am happy to see the other all in show 55 and the bettor 65. But then he rivers me again with a 4
He had better win it!
