###### D

On the Button the range of playable hands is greatly increased compared even to the CO and may include 50-60% of the best hands.

First, the probability of running into an opponent's strong hand is greatly reduced. When playing against one opponent, only a fifth of their hands will fall into the range of top 10% hands. Half the time even against two opponents their hands will not be in the top 30% range.

Second, entering the game on the button ensures that we act last on the flop. Given that the flop is a defining moment in Omaha since even the best hands often do not have a great deal of independent value (e.g. a high pair) this is a very important factor.

In particular, when playing on the button our bets will be 3bet and called more often than when playing from earlier positions.

That said, in absolute terms, we will look at flops less than when playing with UTG, UTG +1 and CO - that is, we will often just take the blinds - while our opponents will come into play more often, knowing that our pre-flop bet - range is wide.

The game will take a looser character and the fact of our being in position on the flop is to our advantage. The main issues pre-flop with the button is the process of expanding our range. Since the lower-ranges hands facing have similar mathematical probability when run against each other, the choice is taken on the basis of convenience when drawing on the flop - namely, that is to say on the flop, as often as possible, we have the opportunity to bet (if checked to) or 3bet (if bet to) with good chance of winning the event of a prolonged rally.

First of all, I propose to extend the pre-flop ranges from trhe button to include hands, which are easy to assess on the flop - and, through this, to respond after we have called an opponent's 3bet preflop.

This factor is particularly important because we will be getting 3-bet several times more often when playing on the button than when playing in earlier positions.

Once again, we note that our range will depend on the opponents in the blinds, if our rivals often tend to fold their hands pre-flop or on the flop, we can play looser whereas against loose opponents will have to use tighter tactics.

It is important not to place too much emphasis on i the overall play of a pre-flop raise, call and 3 bet, and such other position plays against the button as many strong players take the position of a  bettor into account.

Likewise the same holds true when choosing a response to an opponent's pre-flop 3bet.

So, when on the button our hand ranges will include, as well as strong cards:

1. Low connectors, including those with gaps
2. Most double-suited hands, especially hands with paints, pairs and straights.
3. Hands that contain multiple court cards
4. Most suited-ace hands

###### SB

Playing from the SB is not that much different from playing on the button.  The improved mathematical chance of encountering an opponent with a weak hand is counterbalanced by the fact that on the flop we will open up the game.

Accordingly, the width of our range will not differ greatly from the Button-range.
