KK in 3-bet pot, A hits the turn. NL2k

[good2cu]

Preflop: The call is fine, but I personally 4 bet light sometimes so I would also 4 bet this. If you never 4 bet light I'd call here everytime.

Flop: After just calling preflop I'd c/r here a large portion of the time to counterbalance when i bluff c/r the flop with missed overs.

Turn: Nasty card. Your hand looks like 66-QQ and the villian will mostly like bet all his aces, 9s and all hands that don't beat 66-QQ. At this point you have to make an estmation of how big his 3 betting range is. As described I'd either shove it or call. I don't see much of a difference in the EV. If I c/c the turn then I probaly c/c the river if i think the villian is capable of bluffing in that spot. If not c/f).
