Villain is pretty unknown since I just sat, but he has min-raised me on the turn before and I folded top pair to it, so I figured he might be just doing that again as a steal thinking I had nothing. He might also have me outkicked, an overpair, or some random hand with a 3 in it, but I have FD outs as well.

Is this a push?
