Different styles for BB defens

[waffle]

If the PFR has the worst hand in position, and you are going to raise him when he bets, betting the flop is -EV. He may not "KNOW" you're going to raise, but the flop bet is still -EV. Calling the raise is NOT a mistake, and I never said it was "even more of a mistake", but the inital flop bet is. A common concept is that your odds may not be as good as they seem if you fear a raise later in the betting round. This idea is what I am getting at. Drawing odds wise, what's the difference between the BB betting 2 SB, and the PFR calling, from the situation where the BB check raises the PFR? 2 bets go in either way, yet you would argue that the PFR only makes a mistake in the first situation.

Basically, every bet that he puts in to the flop with the worse hand is costing him money. So why not c/r?
