Question on HOH Vol 1

[Sentinel]

As you know from my other post on the subject (recently updated so please respond) I am having some trouble with equity.


1) In HOH Vol 1, page 135, Dan goes through a lengthy process to determine whether he should call a reraise that would put him all in, with AA. Here he breaksdown all the possible hands villain holds and assigns them a percentage. Then he multiples that percentage by his chance of winning under each scenario. Then he adds them up for a final figure and compares that against the odds on offer.

So, is this Dan working out equity? Never seen it done like that before.


2) for the rest of the odds section, he doesn't refer to this method again. Instead, like on pages 149 and 155, he just says things like "he might have the goods, he might be bluffing but at this stage of the tourney, just fold" and "unless you know for sure he has AA, you have to call."

So irrespective of whether 1) is equity or not, what's with the differing methods of figuring out whether to call or not? And if neither is equity based then you have 3 potential ways to decide: equity; doing all the percentages and adding them up, wondering what he could have and pushing if you think it's more likely you're winning.

Kinda confusing!
