Spenda, I think you get frustrated too quick for BC threads, FWIW.

One spot you got me thinking about was the "cbet air" line. Tons of villains at all levels I've played automatically "call one street" with almost anything: any piece of the flop, any half-way hopeful draw, any over card, etc. As bad as the play is, it works great against someone who one-barrels (cbets flop, checks turn) a ton with air and two-barrels with a TPTK / overpair type hand.

Taking the "cbet air give up" line too often allows bad opponents with mediocre hands to play perfectly against our line.
