idk, i think if you check the flop and try to get value from your kings you just end up getting in too deep on the turn and river with a marginal hand a lot of the times.

My philosophy, and reason for always betting the flop in these spots is simple. Whenever there is a scenario where my opponents expect me to bet whether I have air or a hand, I generally like to accommodate them. I don't really believe in trying to squeeze significant value from KK when an ace flops. I treat that scenario as if I have flopped middle pair or a weak draw, and I bluff the flop with a couple of outs and a hand that actually has decent showdown value if called. If there is an ace in my range when an ace flops, you better believe I am going to bet it whether I have the ace or not (assuming a HU scenario with fold equity)
