Just how nitty is this guy?
1) Would he be doing this with AJ?
2) Would he do this with an over PP (QQ+)?
3) If you think he's doing this with only a set, would he pay you off if a
comes?
For #1, would you have any fold equity if you shoved as a semi-bluff?
Ditto for #2 (probably not likely)?
For #3, you're getting about 3:1 now for a call, so you'll need some implied odds to call with the FD, which you might or might not have depending on how nitty this guy is.
