Also +1 that this is a good hand to add to your preflop 3b bluffing range against this type of opp, more so if you have people with squeeze tendencies in the blinds, less so if you have stations in the blinds.

It's a good hand, because you block a lot of his strongest combos with your A, if he calls it's a hand that plays well post flop (can flop the nuts, can flop strong draws, can flop top pair and when it does not flop well it's an easy fold) and if he 4b it's an easy fold (unlike hands like AQ or AJs).

It's also a good spot because you have position and if he plays decently well he should hate flatting the 3b OOP.
