Today I wanted to talk about a weapon that I'm learning to use: 3-bet preflop.
Is basically the raise preflop reraise the villain. With what are all advantages.
they will be forced to make a complicated decision preflop, and if you call, an even more complicated in the flop if you want to play the hand. Most, nits, go down the easiest path for them, which is the fold preflop or fold on the flop with pocket pairs. Besides, we play the hand in position (except for r / r to defend our blind), and many people can not believe a raise preflop and put us on air (especially if we have a preflop raise more than 6-7, but when we put a 3-bet most people, including fishes, tends to get in a good hand.

What conditions?

Position.
Position of the preflop raiser and ours. Ideally, a 4BB raise a thief CO r / r us in the button to 12BB, but not always. Beware reraise a raise in early position.

Villano.
The higher the preflop raise the villain, the more effective the 3-bet because they have a wider range of hands and most of their hands may not be facing a reraise.
The lower the Went to showdown, the better. Obvious. Failure to do so with fishes with WSD of 40%.
And the higher the fold to continuation bet, the better. Although I think this is more because the fold secondary to cont bet most of the time referred to boats in which it has been a single preflop raise.

Our hand.
Hehehe, I have written a billet and I have not spoken of the hand.
Well I think it depends a lot and we can do with a relatively wide range of hands.
Aside from the obvious JJ + and AK, we go accompanying slowly with other hand. 99 + and AQ + should be the base, and then hands that in general we are not sure whether a call will be merit EV + r / r with position, such as garlic, T9s, KQs.

I think it's a matter of situations that range of hands, so in the appropriate situation reraised I would play, given that we play with a big stack, a very wide range of hands:

Any couple
Suited connectors (AKs-65s)
Connectors with a hole (AQs-86s)
Aces suites (AXS)
