I agree with that and disagree that it is so easy to fold as played. Why is he raising you on such a dry board? Shouldn't he be worried that you could have AK? If he has a set, what turn card is he afraid of? His hand looks like basically exactly AK or air, in which case I would probably call again unless I had more info on his playing style.
Exactly my thoughts, if Villain really did have AK here then he played it pretty terribly. He should know that if SB does have a K, he's going to stack him on later streets anyway on such a dry board and raising now with AK eliminates all SB bluffs or exactly what Hero had here (pocket 10s).
On the flip side, I know there are many players here that are capable of bluff raising this flop with nothing. Their thought process, from what I can garner, is if SB doesn't have a king how can he call a raise? Therefore, I should raise with my 89o. Which makes bet/folding pocket 10s in this spot super exploitable, against most competent opponents.
I really prefer a check call here, at least through the turn. We have a range advantage on this board, being the preflop 3bettor and if Villain is capable of triple barrel
bluffing anything but Kx in this spot then good on him. This is also why I advocate check/calling strong Kx on a strong board like this against aggressive opponents, as it's more profitable sometimes then just going bet/bet/bet. Aggressive opponents can't help themselves sometimes, and will triple barrel with a lot of random crap if they sense weakness, especially in blind versus button situations. It's all player dependent imo, but this I feel is the less exploitable line.
