Under what circumstances would you go all in with AKs (or unsuited, for that matter)? For example, I just sat down with 10 dollars at the 5/10 penny tables and the guy to my right went all in with 2 dollars. I had AKs and called. The guy directly to my left pushed all in with 5 dollars (3 more to call). I knew it was a coin flip, and I have no discipline, so I called. In the long run that call will have negative EV, so I know I sholudn't have called, but I'm looking for justification, damnit! Is the only circumstance for calling an all in when you KNOW that the person doesn't have a pocket pair (and how could you really know?)
