25NL, random unknown, i am happy to get all in here...This seems like a standard bet for a good hand, like AK or AQ (this is a big flop, but AK doesn't want to see hand go a lot farther)....If he is pushing top set like that, go ahead and make a note that he plays real big hands real fast....otherwise, i'd say most of the time your good here -

my 25NL experience is that basically you can't give them so much credit - The big turn bets earn more of my respect as they scream set - I think this villain has a big Ace and wants you to go away...I haven't run into that many players who push a big set that fast....
