I don't like the K2 push from the CO either.

I'm perplexed by your statement that SNGPT says that it's a good push... I don't see it, though maybe I entered something wrong.

For BB calling any two, SB maniac, Button maniac, it's -EV. It's possible that these hand ranges are incorrect, but I think that it can be argued that they are at least reasonable.

An interesting thing about this is that if BB is any two, SB is any two, and Button is maniac--- it's +EV.

The OP says "Now in retrospect, I realize that it is likely that I will be called in more than one spot here being so short, and therefore I may need to be stronger Than K2o to push here."

This appears to be wrong. The more spots that you get called in, the more +EV it becomes.
