In the end I checked, but while doing so was almost certain that it couldn't be the right play.

I believe that it's correct to bet/3 bet allin, however annoying it might be.

the trouble is that you're basically a small dog to the 'big spade + 2 overs' range and a big one to all his real hands. so, yeah, checking sucks, but bet 3 betting isn't any better if he even remotely pot commits himself, and bet folding is really bad. IMO it's between checking and bet/calling (and hoping an A, K, or spade doesn't hit on the turn) and I'd rather just check and then raise any blank turn card.

btw this is somewhat tainted by him being the SB and having a tighter call range than the BB.
