3-bet and fold to a cap?

[Argus]

Villain is a 22.5/14/2 TAG over about 750 datamined hands. At the table he wasn't getting out of line, and I hadn't played any notable hands against him. In fact, we weren't often in a hand together since we'd take turns playing against the LAG in the SB.

My plan here is to 3-bet and fold to a cap. If villain is ahead I'm drawing to 2 or 3 outs, and I can't see him capping a worse hand. Is this a good line? Why or why not? If it isn't, what line is better?
