The UTG limp/call from a decent player is usually 22-99 and sometimes suited broadway cards or similar hands or AA/KK. You bet half pot on the low flop. He has to assume you usually just have overcards. The big raise preflop looks like AK/AQ. I would say he usually has a lower pp. Sometimes he has something like QJs and is representing a pp. Sometimes he hit his set or has a big pair. I wouldn't fold, but this is not a good situation.
