I played the £20 NL 1 rebuy at Notts tonight and had a great time, lots of blondites there too and I think 3 made the final.
I went out on the bubble with AK, I chatted to Orlando on the way out who said he would play it differently to me. Jammer walked in on his way to the cash games and thought the situation was marginal - so I thought maybe more thought was needed.
The situation (as much detail as I can remember).
11 players left, 10 get paid approx 870000 chips in play, blinds 4k 8k. My table is 5 handed.
I have 77000 before posting the SB.
Table chip leader is 2nd to act and open raises to 24k total, button folds and it's me to act.
I have

.
The BB is a friend of mine who I have played with a lot - he is tight and I'm fairly sure he's folding so no need to worry about him.
Chip leader is a youngish player who I have not seen before - he has quietly been building up his chips over the last hour or so since I moved to the table. (I have played 1 hand in this time and my stack has wained slightly). He has raised quite a few times and has had no real resistance.
He was involved in a big pot about 20 minutes ago where he called a raise with AK, flop came K high and he thought for ages before calling a check raise for about half his stack (other guy had KQ and he won).
I decided to go all in which made it a further 53000 chips him, if he called and lost he would still be left with ~ 80k which is around average.
My reasoning was:
1) I am out of position and would be at a disadvantage having to act first on the flop
2) I wanted to win the comp not sneak onto the final table and get £50.
3) My raise was just about big enough to put him to a decision - it would not be an automatic call.
Orlando said he would call and gave various good reasons - hopefully he'll post here and elaborate as I don't think I'd get it all right.
What would you do in my position?
What would your plan be for future betting rounds (if there are any)?
