It is a mistake to 3 bet AJs against this player. AJs has a lot of value in calling since this player will only continue to a 3 bet when he has you beat. You want to 3 bet a lot as a
bluff and tighten your value 3 bet
range against him (AK
KK+) Id even
flat QQ against SUPER nitty people. 3 bet nits as a
bluff more often though with stuff like smaller
suited aces,
suited Kings,
SC's and so forth.
Against a looser player who will splash around in 3 bet pots with
marginal hands (hands that AJs smokes) you can place stuff like
TT-
QQ, AJ+ into your value 3 bet
range. Your bluffing
range will stay roughly the same against this player but you'll want to 3bet less as a
bluff and more for value.
BTW your
c bet size is fine here, I would bet around this much if I had
AA or
KK and this
flop came down. On boards that are not as
draw heavy tho I think it is just fine to 1/2 pot it in a 3 bet pot.
Also, if you choose to bet the
turn I think it needs to be a
shove. But it really does not look like you have a lot of
FE here.
