But he knows it's me and I know he knows it's me. Plus he was playing tight today and I don't know if he realized I realized that.

Part of my point was how do you know he (or the SB) is playing tight? Unless you can see what he's folding there's no way you can know this information. I play hyperaggressive heads up, but I've folded the SB 4 or 5 times in a row on many occasions because I never held a card higher than an 8. I'm sure my opponent thought I was playing very tight.

It turns out you were right because he confirmed it but at the table I don't think it's correct to assume something like that with so little information.
