I"m not so sure about the "old guys are nits" stereotype - I know it doesn"t apply to me, nor to a lot of the seniors who frequent DTD - have you played Greek Jack or Ali Mallu?
I"m not trying to beat on you David, just trying to make the point that we need to assign a range before we make a decision, all we have to work with here is....
UTG raise, due some respect.
"Old guy" somewhat likely we should range tighter.
Villains previous comment, could be construed as "won"t be light" or " is likely to fold often if 3b"
3x open raise size, again could be construed as "weak" or "strong" but most likely villain is a dinosaur and its just the size he uses cos he doesn"t know 2.25x is the new 3x.
The bottom line is, this is a marginal spot in a field were I suspect you have an edge. That villain shows up with KTo is irrelevent.
