After early level success, I had a combination of bad table position and bad cards. With about 1/2 the field gone, my double-avg size stack was tiny. I have maybe $12k (avg is $35k) and I finally get a hand: KK.
An action player who had made many marginal plans and got rewarded this evening is on my left and he raised (I am in the blind) to like $1800. Now I can re-raise all-in, and expect him to fold and rake a pot of like $4k. OR, I can bet half my stack (say $5k) and expect him to CALL, and expect him to call the post-flop push, as probably a 3-1 favorite (as he probably has a weak Ace... yet again).
I dont know how you play, but I am NOT letter a weak ace get away pre-flop here. I bet 1/2 my stack, he calls with Ah3h. Flop is Th9h3c and when I shove, he now calls again as a dog, because he hit the flop. But in the end, he draws out and I go out.
But, that is the way I play.
