Hi, guys, should I be more aggressive on the flop? When he checkraised me on the flop I have put him on AK, KQ, something like that. However, I didn't have any reads so he might also have two kings, but in most cases this is unlikely ( he would reraise me). I think my call on the flop was a little passive and then because of one passive action I made a passive action on the turn because the heart came, giving me the nut flush draw. However, how do you think I should play a hand? I assume I should be more aggressive on the flop.
