villain (25/20, seems aggro) 3bets quite a bit, and i usually fold but sometimes 4 bet. i don't think i've called a 3bet before.

at first i was planning to c/r on a non-ace flop, but then i figure i might play TT-QQ like this and he's more likely betting than calling.

is there a definite better way to play here?
