A5 in the SB, A on flop, opp raises ($16)

Opp's HUD stats were about 16/3 at this point. Should I have check-raised all-in here? As played, I have to fold this, right? I hate playing with an awkward stack size that's a bit too big to shove preflop but too short not to raise preflop.

I think u should fold this hand. He cold have lot of nice hands with this flop(A2, 22, even AJo) or he just has a flush draw. How does this guy was playing after flops? Tight? Agressive? I think U made a nice fold but depending of the situation I cold go all in. Call is ther worst decision IMO.
