he has to know that a bet (or in his case raise) that splits villain's range is often wrong no matter how much (non-fold)equity you have.

[/ QUOTE ]

by this are you refering to a raise or bet that folds all worse hands and gets called by all better?

I admit your input is insightful.

also how dcoes .41= 33%??

I think he means .41(41%) > 33%

When playing .01/.02 No Limit Cash, I use this information all the time. Most everyone's range is the top 70% of hands, so things are pretty easy.

no, if you are more than a 33% favorite to win the hand on average which is calculating your equity, which i did and found it to be 41% with the situation i used. Since you will win 41% of the time in this spot and you only have to put in 33% of the pot to call this means it is a +EV call since 41>33

yea, ace you asked if i do this alot, it is fairly simple math, granted i am an engineering major and was always good at math, but if you think thru it a little it becomes second nature. There are so many different scenarios, most of the time you need to take into account fold equity, or multiple cards to come. I hope you understand this a little, again feel free to send me an IM, i left my aim screenname in the PM to you, please do not reveal it to anyone else, thanks.

I understand this at a subconcious level, but can you give me an example of a bet or raise that would not split a players range? Would this be done through the manipulation of YOUR speculated range? If I only bet out and then went over the top with a set, you would fold worse than a set, but if i i make the same play with a flush draw and air sometimes, it prevents myself from splitting your range?

nice article. note that it is intended to teach the concept of ranges not implied odds.

I find an easier way to do ev calculations in these situations than the one Brian used is:

EV = (p(winning)*total pot size after you call) - cost to call

so for his first example

EV = (0.26*109.5) - 45 = -16

(somewhere I or Brian have got the pot size wrong - if someone could check this that would be great. After the preflop betting I get 6.5BB pot, then a 6.5 bet which is raised so we have to call another 45BBs. So pot after we call the raise: 6.5+6.5+6.5+45+45)

[Acemanhattan]

i like your method much better i didnt check pot size but the math was certainly easier.

It's a real service to the poker community that he chose to ignore them, though

[/ QUOTE ]It could be that in the space of an article he was not trying to teach every aspect of winning at NL Hold Em and instead focused on one concept that winning players understand and many beginning players don't even think about (hand ranges).
