Here is my input.
Based on what we know, which doesn't seem to be much, guy popped it to 10x with A2 suited, but we don't know the position. This is our only refrence for the hand in question. Based on that, here is my thoughts.
Very simple. FOLD. He has shown a wide range for any number of different positions. He could be holding AA, or as mentioned K2 suited. Another option is to call the preflop raise, hope for unders and hammer the flop. I think you might get the suited cards out, unless they hit 4 to the flush.
