I think that was more true a year ago. Even SSNL is starting to catch up with overbetting tendencies, and I see it more often now than I used to. I know I've been snapped off light plenty of times by decent players in spots like these, but then again my image is far from clean where I play so there's always more danger for me when I do stuff like this personally.
If you're in fact Hero here and vs a guy you know has a fold button and whom you've rarely (or never) has been out of line against over a decent sample of hands, then sure go ahead and fire away. But chances are, that if the above is true, you're probably not the kind of guy who does these plays at all.
If you start overbetting K9 and stuff here it obviously gets a lot tricker for villain to bluffcatch, but in my experience people either have nuts or air so if villain feels like catching it shouldn't matter
that much if we overbet or fire 66%. His rivercall kind of has the same EV either way so it just comes down to whether he wants to follow through or not, which is why this feels a bit like spew to me.
One thing to note though is that the ace on the flop is a club, so villain cannot both have TP and block the nutflush (which is a good thing for us as played), and given positions he should rarely have AxKc (which again, is good for us).
What I mean by that last part is that if villain has a bunch of combos in his range that blocks the nutflush, he has more reason to bluffcatch light because our overbet should make less sense to him (and it also lessens the chance that he goes for the sick nutblocker bluff himself.
)
