Nice hand.. but the short stack is just about to be put virtually all-in on the next hand. Is it worth risking bubbling out with this hand? I eventually did push, and the blinds folded. However, I'm not really sure about the play. That brings us to our next hand..

Wow, i'm a luckbox. However, if I push and get a call, the BB might just fold and sneak into the money anyway. Is there a better way to play this, or should I just shove and risk it?

Forgot reads..

The SB has a very wide calling range (maybe top 60%) and has been a giant pain in the ass by pushing over the top on my steals. The BB is a very solid player by $6 standards, but is a little too passive. He'd probably call with top 25%.
