Can someone define 3bet for me

I have been watching a lot of the videos on this site and I cant quite understand 3bets.

Could someone define 3bets for me.

How big are they? - I often hear that people like chuck dont like the 3bet size a player makes.

What position are they made in? Is a 3bet something that can only be made OOP?

what kinds of plays are they used in?

What kind of players are they made against?

Thanks

3bet is when you reraise someone

As for the size of a 3 bet, I was always under the assumption that a good size for a 3bet was 3-4x the original raiser. Say the BB is 100, and the raiser makes it 300, a good 3 bet would be 900-1200. And I think you have to have either a good read on your opponent (where you think he's making a move, with junk), or you really have a great hand. Also, If you feel your opponent raised as a move, with junk, you can 3 bet w any two cards hoping for a fold...of course if your read is wrong, or just playing a maniac, you could get yourself in trouble.

a 3-bet is the 3rd bet on any given street. So :

Bet - Raise - 3-bet.

Pre-flop, the BB is the first bet.

the size of a "good" 3bet depends on so many factors omg lol :x

OK thanks I get what it is now.. what confused me is that the usual amount to 3bet is 3x the raise.

So its fairly likely that a 3bet will be a bet which is greater than the pot size. Im thinking this because a standard raise is 1/2 - 3/4 pot size so a 3 bet will generally be 1.5 - 2.25 x the pot size.

This statement can be confusing, so I'll try to clarify.

The term "3-bet" originated in Limit Poker. Since the bets are restricted, it is easy to count them. But the term has carried over to No-Limit Hold'em and is a bit more difficult to define. New NL players should know that on any street any 1st bet bigger than the minimum amount bet allowed is considered "2 bets", but isn't really called that in NLHE. It's just called a raise. Then the next raised bet would be the "3-bet". It isn't necessarily the "3rd bet".

For example:

.10/.25 NLHE game.
4 limpers pre-flop.
On the flop, there is $1.00 in the pot.
The first guy bets $1.00.
The second guy folds.
The 3rd guy calls folds.
The 4th guy raises to $6.00.

In this example, there are only 2 actually betting actions. But the 4th guy is considered to have "3-bet" since he raised the first bet that was higher than the minimum bet allowed of 25c.

Take the same example, but:

The first guy bets $1.00.
The second guy calls $1.00.
The 3rd guy calls $1.00.
The 4th guy raises to $6.00.

Now there are 4 betting actions, but the 4th guy is still considered to have "3-bet" since he raised the amount of the 1st more-than-minimum bet.

Hope this helps.

I don't know about confusing, but as far as I've every understood the term 3-bet and 4-bet that statement was exactly right.

It's true that the terms originated in limit. And while it doesn't carry the exact meaning (in regards to actual bet amount), it does still carry the same definition. A 3-bet is still the third bet on the street; it's the reraise. The first bet on the flop in NLHE, irrespective of the amount, is still nothing more than the first bet. The next bet is the raise which is then followed by the 3-bet. Think about it this way, you're first to act on the flop...what do you do? Do you c-bet or c-raise? Obv you c-bet. At a live table when you're first to act on the flop you don't declare "raise", you just bet. The next one to come over the top declares "raise".

^^^ As I understand it.

Also, the part that many misunderstand is that the BB is actually considered the first bet in the preflop round. So in another example:

Player 1: SB $.25
Player 2: BB $.50 (this is a live bet and considered the first bet PF).
Player 3: Raises to $2.00 (this is a raise...a 2-bet, if you will).
Player 4: Raises to $7.00 (this is the 3-bet)
Player 1: Folds
Player 2: Folds
Player 3: Raises to $22.50 (this is the 4-bet!)

Now I'm confused. I'm only 80% sure here, but some logic comes into play.

Why do people call the minimum bet after the flop a "min-bet" and not just a "bet"? And you can "c-bet" any amount, but a "1-bet" or "bet" in Limit is the 1st restricted amount. Then in NL, if you bet more than the minimum bet and you said "raise" when you are first to act, you would technically be correct since you are "raising" the bet amount above the minimum. Even when you are first to act in live games and you want to use more than one motion with your chips, you must announce "raise" or the bet amount in order to keep a "string bet" from being declared. So anytime you are first to act and bet more than the minimum, I believe that is technically a "raise" though the term is not always used right there.

Like I said, I could be wrong.

I don't recall hearing that term, but really it's same thing. It is just a bet. The only reason anyone might call it a "min-bet" is to specifically call out that someone did in fact bet the absolute minimum they are allowed to bet on that round, imo.

A c-bet is the same regardless of whether it is a variable amount in NL or a fixed amount in LHE. C-bet = continuation bet. Continuation doesn't assume amount. So if you raise PF then bet the flop, you've c-bet. The only difference is that in NL you can size your c-bet properly according to pot size to run off the chasers (well in theory at least ).

If you're first to act, afaik, "raise" is not correct. What are you raising? There's been no action on the hand, so you're betting. You don't raise against what is the required minimum bet. You raise to another cost level after someone has bet.

Even here you would not annouce raise if you were first to act. You would declare your bet amount if you need more than one motion.

From Wikipedia http://en.wikipedia.org/wiki/Betting_(poker) :
Raise
To raise is to increase the size of the bet required to stay in the pot, forcing all subsequent players to call the new amount. If the current bet amount is nothing, this action is considered the opening bet. A player making the second (not counting the open) or subsequent raise of a betting round is said to re-raise.

No problem, you're forgiven.
