Betting

Is there a good book where i can study the size of the bets?

I know the basics but i want to to take advantage of the most possible situations so that i do not put in more chips than needed in marginal situations or to get the maximum value with good hands.

You playing NLHE cash? Full-ring? 6-max?

I'd probably go with Sklansky's Theory and Practice book, it's pretty advanced but still better than most of his early writings. I'm not sure which book to recommend if you're looking for a more basic look at cash games. I know Harrington just came out with a new book, but I haven't read it so I can't attest to its usefulness.

I have read books on betting and almost all of them recommend 3 or 4 big blinds. I see this when playing cash games. I would experiment and see what works especially at tight tables (which most are online). On 6 max don't limp unless you are in the blinds or late positions with a marginal hand (sc's), otherwise raise or fold with varied sizes of raises. JMO

Phil Gordon little green book has extensive information on what to bet in x situation, against x-z hands.

Its good book for figuring bets.

Are you talking about specifically preflop bet sizes or any street?

This ^ is what I was going to suggest. (assuming tournament play)

Any street.

Preflop raise is basic.
But raising after the flop, turn or river is a science. Phil Gordons book is good but i need some equations in order to trully understand the concepts.
I do not think tha all good players there know the mathematics behid poker but for me seing is beliving I know i have to play according to pot odds but i cannot take advantage of the opponent's profile witch i think grows or lowers the actual value of a raise.

A lot of times i put more chips than needed there and scare the opponent when i have a good hand , or put more chips than needed when bluffing and end losing more than i i hoped to see a hand.

Well, you can't determine if your bet size was good or bad based on the results of that hand. You have to think about your opponent's strategy. I talk about this in a section on value-betting in my recent book, Poker Math That Matters. Also, No-Limit Hold'em Theory and Practice talks about this quite a bit. You have to think in terms of the EV of a bet-size given an opponent's range. This is a lot easier to do on the river. But, basically, a good example would be if your opponent has 20% of his range that will call an all-in bet of $100. However, his entire range will call a $15 bet. Which bet is better? The larger bet is better even tho the villain went from never folding to folding 4 out of 5 times.

When you're on not on the river, you have to think about a couple things with your sizing. One is chunking up your stack. I talk about this in my book as well, but another great spot to learn it is Professional No-Limit Hold'em Volume 1. You want to think about how the stacks will play out to the end of the hand. Do you want all-in? How can you get that done without making a massive river over-bet, etc. Mixed with that is thinking about your opponent's strategy and trying to get him to make the biggest mistake you can.

It can be tricky business. But, you have to work on this stuff. That way when your hand-reading improves, you can actually do something profitable with the information you gain.

^^ Great advice for any type of game, this is the kind of higher level thinking that'll make the difference in your winrate.

One of the best advices i recived since i joined this forum.
BTW. If you are Owen Gaines aka Qtip i am also honored because you are a great player and a great coach as i saw on the internet.

Well, thx Glad it helped.

I agree with the posters who mentioned the read on your opponent. The cards are important but you don't need the best hand to win if you can induce a fold with a bet on an opponent who will likely be folding.

Sklanskys book theory and practice is very good, but a little bit too mathematical for me. If you use the pot bet button on Full Tilt, you don´t make many mistakes, or bet 75% of the pot and let the draws pay and so on...
