If you analyze it, the 4-bet is probably a little better than a flat call. There is an advantage to flat calling and seeing the flop with position. If Raymer folds to the 4-bet, that is not a great result, but OK. If he pushes, then you have a borderline decision, so that is not a great result. If he calls, that is sort of good, as you built the pot with a very strong hand and position.

When Raymer, pushes, you are probably a little ahead of pot odds. This is button versus BB with 2 aggressive players. How both players have been playing, particularly against each other in late position, is also relevant.
