If these villains are regs that 3 bet light, the chances are they will adjust their 3 bet sizing based on the size of our open. If they didn't however, and continued to 3 bet to 11bb after we reduced our open from 3.5bb to 2.5bb, they'd just be risking far more than they'd need to to win our open and we would be able to fold a fair amount and still make their 3 bets a mistake due to their poor risk reward ratio. This is a great situation for us if the villains are this bad. This does not mean to say we have to fold all the time that we don't have a defendable hand. If they are 3 betting overly large, we can pick hands with blockers to their nut combos like A4 for example and make a small 4 bet when IP, getting a pretty good price on them folding, this works well espeically if we are a little deeper than normal since we have room to 4 bet a little more to ensure they can't flat profitably and also make it a bigger mistake for them to 5 bet jam light since they will need more equity vs our calling range than they will 100bb deep. Just food for thought.

FWIW I'm not actually taking each question straight out of the book, I'm just asking about content relevant to this chapter and asking you to think for yourself in some questions.

Thanks for the replies so far. Feel free to critique each other's answers or whatever. Once we have had a few more responses, I'll post my own answers.
