The "Doyle Brunson System"

[MikeL05]

OK I read the book, I understand the whole "win little pots frequently so you can gamble with big draws" thing.

And I see a lot of people here talking about this.

My question is: does this make any sense whatsoever? He's basically saying that he plays +EV poker and chips away at a ton of little pots... then moves in huge as a likely 2:1 underdog with something like a flush draw or open-ended straight draw. And this somehow makes sense because "it's not his money", it's money he won from other people in little pots.

Two possible explanations come to mind: (1) gambling with draws like this allows him to get big action with his legitimate big made hands, and (2) he has a TON of fold equity. Do you guys really think this is the case? I find it hard to believe that consciously throwing a ton of money into a pot as a 2:1 dog is, in the long run, +EV. Curious to hear some thoughts here.
