£325 ($560) entry tournament in Birmingham (UK), 7000 starting chips 160 entries.

I'm discusted with myself over my performance, but these hands concern me, especially the first one.

Level 1 (25/50), equal stacks. I am BB with 88.

D-1 raises to 200, SB calls and I call 150.
Flop is 78J rainbow. SB bets 700, I call and D-1 raises 3000. SB folds and so do I.

I was worried about T9, and didn't want to risk all of my chips this early in, but overall this is terrible right? He would raise more with JJ preflop, would be unlikely to raise with T9, and if he did have the straight he would probably play it a bit slower.

Second hand. 100/200 blinds.

4th pos. raises to 700, 6th (to my left) raises to 1200 and I call with AKo.

Flop is 77K checked round to me I bet 2000 of the 6000 I have left. SB puts me allin, and I call. Again, bad call? Surely he must have a 7 (unlikely with raise), AA, KK or at best AK?

I am seriously worried about what the hell happened to my game tonight with these hands, could do with some comment from the people on here, would be appreciated.

Just wanted to add another hand quickly.

AA in first position with 6000 chips with the blinds at 100/200. I raise 300, with 4 callers (including BB and SB). Flop is AJ2 all clubs, and I raise 1500 when checked to me, is this OK? They all folded.
