A5, A4, A2, 55 are the cards he can play this way and u have to be afraid from. 3+3+4+3=11 combos. but if we count just the suited aces its just 1+1+1+3=6 combos. u should call here.

You can`t fold this...he`s representing a strong hand here but you have a super strong hand too and he cold have weaker aces so call +1
