postflop play in a 22: trying to steal a pot

[Slim Pickens]

Party 22. My read on the opponent is that he is a solid regular, a good tight-agro player. This turned out to be right as we finished 2nd and 3rd in this one. Here's what I don't understand. How am not able to steal this pot from him? Too big a turn bet? Hint: it's not because he trapped me.
