re: Poker & Having a big over pair to a paired flop.
Keep in mind that there are still quite a few "ands, ifs, or buts" when Negreanu dispenses his advice. As with most all poker advice, it doesn't exist in a vacuum and will have several qualifiers. Daniel would most certainly amend his statement knowing it was .05/.10 at 40BB.
Now if you are in the habit of C-betting, then checking just alerts your opponent and he's going to be afraid you have AT. Once again, what you "should" do on a singular hand does not exist entirely in a vacuum. It will also have something to do with how your opponent reads you, based on your previous play.
