check-raising or leading is standard. Calling can be considered if you have a good read on your opponent as Rempel describes, but you really need to know your opponent pretty well.

As for bet sizing on the c-r, you can make it about $207 to go which will leave you about $180 behind in what will be a $500 pot or so if only one guy calls. Therefore, you can't be priced out on the turn.

If you want to get cute, and you're afraid that a pot raise will scare of a KQTx draw, you could consider making a bet that guarantees you'll always get at least 3:1 on the turn. In this case, that'll be about $170 (a $135 raise, about 4/5 pot). In this case, I don't think the difference is big enough to make anyone change their mind about calling or folding.
