I push in both situations. If he has 77 in the 2nd one, well that sucks. I think he will have AK more often than he will have 77.

Push hand #1. Party is full of people who love to gamble. You could be up against AA but that will be less than half the time is my guess.

Call hand #2 and look for a cheap showdown unless you hit one of your 4 outs to beat 77. Not sure what to do if he pushes the river. I see stop-n-go from big made hands all the time: they check/call when there are a lot of people in the pot, but they can't stand to think about getting checked behind on the turn heads-up so they bet it themselves. My read is the guy has something he thinks is a big hand. Whether he's smart enough to realize that only a set is a big hand here or not, I don't know.

I'm pushing both times.

1. If it's KK vs AA...that's why we have bankrolls

2. SB might have a set...but it's also very likely he has two pair.

As usual, I agree woth Kenny on both hands. Push them both.

Actually I agree with K3nt on hand #1. Kenny copy-catted (new word) him.
