Seems really close tbh, we have a 20 bb stack far from the points and $$ so not in a huge hurry to take small edges.
Our read "solid rather than aggro" suggests his mp opening range is tightish, that range is the key factor in our decision.
If its something like 77+,ATs+,KJs+,QJs,ATo+,KQo .......
3 betting will find a fold 50+% so if we bet 4,700 ~27% of our stack we win 4300 when we find a fold. Its probably marginally +ev but is a high variance option, if villain flats we have position but again, high variance.
I prefer 3 bet to ~ 4700 over jamming and dont hate folding.
Edit: Jamming will turn a profit.
