Short handed and short stacked at 5/10

Do you have any stats on this guy? I mean this seems like he has a straight and is just trying to protect against a flush. I dont like check-raising this turn, if you think you are winning then lead out. This way you can gain some more information without risking as much. Even if he is short-stacked, with this type of flop, what do you think he is calling you with that you are beating. I think that a bet of like $40-50 might be a better bet than the check-raise. I put him on at least A7, u may be lucky and he may have bottom 2, but I still think that this is not that likely. I think you played this too aggressively, I think he may have a huge wrap here or something like that. Even if he is short-stacked, I dont think a player in PLO is going to risk ~1/2 of stack on just bottom 2 or something like that. If you have any info on this guy, that would help a lot.
