Personally at this stage i'm not going to get too involved with a big stack that can break me. But if i'm feelin it i may take a shot at him with a raise somewhere between 6-8k and see what happens. If he pops me back, i'll fold, if he calls, i'll use post flop strategy on how the flop comes, and if he folds, lucky me and continue on. If i'm only an average stack on the bubble like that. I'm generally a pretty passive player and trying to survive.
