[I don't play this big; a "very good reg, huge winner, very balanced. I hate playing against him" reg would cause me to move to another table.]
I think with the stack sizes, you can't call the three-bet pre. He knows that flop SPR is going to be 1.5; he's loading up for a hand-ending jam on the flop. If effective stacks were 150 BB or so, I think you could see a flop. But of course, if effective stacks were 150 BB, he wouldn't have limp-reraised his aces
