Explanation of Three-bet

Bets in poker can be assigned numbers to show where they fall within a sequence of bets.

One-bet – The first bet in a sequence
Two-bet – The first raise in a sequence
Three-bet – The first re-raise in a sequence
Four-bet – The second re-raise in a sequence
Five-bet – The third re-raise in a sequence

Note that the first open-raise preflop in Hold’em and Omaha is referred to as a “2-bet” because the mandatory blind payments are considered as the first bet of the sequence. This can cause some confusion amongst novice players. It’s common for a postflop 2bet (the first raise) to be mistakenly referred to as a “3bet”.

How to Use Three-bet as Part of Your Poker Strategy 

3bets happen routinely both preflop and postflop in the majority of poker variants. Postflop 3bets are a little less common since they are often heavily indicative of strength. 

For example, in No Limit Hold’em and Pot Limit Omaha, it’s extremely rare for a player to 3bet the flop without holding a strong value hand. While some 3bets should be a bluff according to poker theory, many players only ever three-bet postflop for value. 

The preflop betting rounds are a slightly different ball-game, since even the average recreational player has often been exposed to the idea of re-raising a preflop open (3betting) as a bluff. While the average player still 3bets way too tight of a range preflop, the line is less indicative of strength than a postflop 3bet.  As a rough guide, the later the street the 3bet occurs, the greater the amount of strength that is represented.

Preflop 3bet Strategies in Hold’em

Many players advocate making use of polarized 3betting strategies preflop, although depolarized strategies are becoming increasingly popular from a variety of position at the table. 

Polarized – Implies 3betting a selection of strong value hand and a selection of semi-bluffs. The semi-bluffs range will typically be comprised of speculative holdings such as suited connectors and suited-gappers. They don’t have a lot of raw-equity preflop but still have the potential to make big 5-card holdings by the river. These types of speculative 3bets are especially useful when facing opponents who fold too frequently to preflop 3bets.

Depolarized – Implies 3betting a range of hands for value/thin-value but never semi-bluffing preflop. Although the line between thin-value/semi-bluff can become blurred at times, a depolarized three-betting range won’t typically involve any of the lower ranked suited-connectors and gappers such as 57s. A depolarized 3betting strategy is especially useful when dealing with opponents who defend too frequently against 3bets.

Preflop 3bet Strategies in Omaha

As we increase complexity into a variant by adding additional cards, it becomes harder to describe strategies as depolarized/polarized. The lines between the different types of approaches become blurred. The general consensus regarding Omaha 3betting strategy is as follows -

- 3bet the absolute best hands for value. i.e AAJTss, AAKK, AKQJss etc etc.
- 3bet a selection of speculative hands with “smooth” equity, especially rundowns such as T987ss

One might describe this strategy as “polarized” (since we are 3betting a mixture of value and speculative holdings), but it could also be considered as “depolarized” since T987ss just so happens to be one of the best hands in PLO despite the fact that it doesn’t have as much raw-equity as holdings with bigger cards. Hence, the terminology itself loses importance – but the broad view generally accepted strategy is that advised above.
