Lately I've been having trouble deciding between aggression and patience when its 5-6 handed and I'm the short stack.

I'm saying bad push. It's 6 handed. I would say 4 handed or less, it wouldn't be bad, though. I'm not saying that I wouldn't have made the same mistake, though. That's such a marginal hand that you really don't want to risk your tourney on it especially when you are in the BB.

I wouldn't have pushed here. You likely have the best hand, but you don't want any action with it. If you get called here you are definately behind, no? If you want to push-buy this pot, it should have been done on the flop I think. After checking once people will rarely give you credit for a good hand imo.

I check, and if someone bets I'll likely call, and then do the same on the river. If you get pushed into on the turn, I fold.

I play it the same way. Check the flop, push the turn. Most of the time you'll be ahead, and those 350 chips will look awfully nice in your stack.
