4-handed tourney situation.

[Plaxus]

34 players to start, down to final 4. (top 6 pay, though very heavily-weighted top 3)

Blinds 300/600 no ante. Stacks in positional order are approx: SB = 16K, BB = 3K, UTG = 8K, Button 5K.

UTG folds, I am button with QQ. I've been able to steal a healthy portion of blinds preflop and I know the players all have some respect for my raises.

SB (chipleader) is a loose player. I've seen him commit a lot of his chips earlier with drawing hands, as well as playing all-ins with low pairs. He got to be chipleader with Ace-rag against KK... Also won a big pot with 55 vs TT and spiked a set. He may play with me if he has anything at all..

BB will not protect unless he has a monster.

I make my standard 2K raise. SB comes over the top to push me all in. BB folds.

What do you do? Is the decision automatic either way?
