I think it is fine, and I am paying off a raise. He could potentially have a K or an 8, but I think that given his play, it is not so likely that we don't have value in our bet. Remember, the T completed gutshot draws, so he would of had to be peeling with a gutshot (which he probably folds), or a gutshot with a pair (which he probably bets or raises somewhere). Furthermore, on the river, many opponents get scared of the checkraise not working, and just bet their straights.

As for the call if he check raises, I think too many people bluff with worse hands. Beware the "Schneids play" (or is that only a river raise, and not a check raise?).
