KK on the bubble - Sat Final Table

[Lurshy]

This was from a 23+2 PP Millions IV Satellite. The top 8 get buy-in to semi-finals. 9th place goes to bed with less then Sat tourney buy-in. 80 People started. 9 are left. We've been playing 9 handed for about 20 minutes!

This is from memory (can't find the HH this morning grr)

I am one of two short stacks at the table. We and most other stacks are playing very conservatively. A couple of Large stacks mix it up on occasion, but have usually given up on pots b4 the showdown. I've done two steals in 4 orbits to hold my own.

The other short stack after being desparate, doubled up. Based on Stack/blinds, we are not desparate, but with so few opps, things are very dicey.

Blinds 200/400
