5NL AK from SB - hit TPTK but get 3bet

[nonofyobiz]

ouch. well preflop I was thinking if I flat I keep in his wide range of hands, plus if I miss flop I can get away from it easy. I just didn't like the position.

Should I always 3bet AK pre?

Should I always 3bet AK pre?

not necessarily. but in this case it is likely your opponent continues with a lot of worse Ax hands, KQ, small pairs etc. so you can get value pre+postflop as well as cbetting appropriate boards and getting "better" hands (which will usually be the small/mid pair part of his range) to fold. so in this case it's a mix of 3betting for value + gaining the initiative so we have more playability postflop.
