I see your points. For me though, I think it kind of all comes back to the classic "If you have a pocket pair, an overcard comes on the flop and you don't make a set, you're probably beat." Now with pocket Kings, a steal attempt is probably worth it on the flop if you're willing to lay down your cards when called or raised. Plus, with those two spades out, there is no way I give a free card to a guy behind who may be holding spades. I think I said check-raise to t175 before, but a good sized "probe" bet (at least t100) is more likely. I'd be prepared to check/fold though after that if he calls or raises me on it.
