It's heads up at the end of a 10 person SNG, and you're playing against me. I just busted out the 3rd place player on a huge hand, and I now have about 6400 chips. You have 1600 chips, and the blinds are 200/400. You are in the big blind. I'm a pretty aggressive and VERY tight player in the SNG, but I've gotten caught with my hand in the cookie jar once or twice already.
(1) Let's say I limp in from the SB. What kind of hands do you check with, and what hands do you go all in with?
(2) What if I push my chips in? Which hands do you fold, which do you go all in?
