$100 bvb bbl 2-4 minraised with A3o

[Scotty_12]

Unknown villian (rare bc I datamine the games 24/7) Raises only get called when way behind preflop, dont like folding -felt I could proceed cautiously on A high flops if he puts more $ into the pot, but that he would play bad enough postflop to take this away. Also he can easily be minraising ATC and not interested in getting involved w/o hitting the flop hard. The flop is obv perfect for my hand without it being T33, and I can get away if he c/r and shutdown if called. Thoughts?
