I think this might be closer than that. Does he really plays TT/77/JJ/JTs (10 combos) like that? Calling a raise on that board (and not 3betting? Pushing that turn? Does he wants us to fold our flush?).
Let's say he plays like that with 5 out of the 10 combos.
We're ahead of KdQd/8d9d and some spas from KdKx and QdQx. Let's say 3 combos. That 3-5 equity. Our pot odds are the same...
