Got down to HU in a regular PP $20 SNG and we were both either AI or folding(more AI) every hand, and I was pretty sure he was raising with crap so I called with A2. He hit the Q, but my question is if you're close in chips and pretty sure you have the advantage(albeit slight), do you make this call or wait for a better hand? He went on to win in a few hands later.
