I actually played today. 135 players in a 105.00 buy in. A few interesting hands late.....
I have about 30k, blinds are 800-1600 with a 300 ante. I'm on the button and the guy in the big blind had just lost a big hand and only had 1600 left so he was all in in the big blind. I knew someone would raise and try and get that big blind.
The guy to my right made it 5k, I look down at A7 off suit and shove all in. I was 90% sure he wouldn't be able to call and was raising light. He folded. So right there I have won 3400 regardless of what happens against the big blind, plus A7 is way ahead of a random hand. I ended up scooping the whole pot. 1600+800(small and big blind) + the 3k in antes + the 5k raise. So 10,500 added to my stack and all I had at risk was 1600(the big blind who was all in). These are the types of situations you can add to your stack without premium hands. I would have shoved almost any two cards there because I'm making 3400 no matter what. If the raiser does call you there is still a chance you can suck out as well.
After the blinds went to 1000-2000 I pick up AA, I make it 4500 and get two callers. The flop is K92, two spades. I shove about 38k and the first guy also goes all in. The other guy folds. He rolls over KK and flopped a set. He thought he was trapping me by smooth calling my raise. I was out.
