Well, we've taken the very aggro route all the way here, so now that the pot is bloated, we may as well push; given this read, he folds more than 7/17 of the time, etc.

I just don't like the fact that we've made the pot big at every opportunity and now have no real choice but to make this play.

edit: I think his range starts with a queen and includes a lot of 2 pair and pair + jack hands, but your raise confused him and now the question is whether he puts you on a really badly played set often enough to fold.
