Any suggestions or help in playing late in a tournament with sane blinds? Particularly 3 way and heads up, as these seem to be my biggest weaknesses now that my game in the 4-5 player range is getting better.

Just finished 2nd in a 14 person tournament at the work game. I picked my moment and took out 3rd place keeping the tall stack from having too much on me (I was 2:1 at worst.) But I'm certain I missed value with my hands 3 way. Then heads up I got creamed. I knew he was running me over, but figured my best option was to wait a bit and turn it around.

It went like this....

Start with button
Raised from SB, fold my rags
Surrender the SB with rags
Raise from SB, fold my rags
Raised with KXo from the SB, he folded
Raised from SB, called with 69o (second best hand I'd seen heads up.)
Flop came pair of 7s, rag, 2 suited. He checked, I went all-in (figured he'd call me the second time around since I had enough chips for him to laydown a bust hand.) He made a crying call with a flush draw (more than I put him on) via K8s or KTs and made his hand on the turn.

Overall, a great finish given that 1/2 the field consisted of regulars at the B&M NL tournies and my lack of offline experience.
