I continue to publish research on Omaha.

At the beginning of the study, we calculated the probability that at least one opponent sitting behind us, will have a top 20% hand (with the assumption that all the opponents in front of us folded). This number is somewhat characterizes the position value from the point of view of mathematical odds.

UTG: 67%

UTG +1: 59%

CO: 49 %

D: 36 %

SB: 20 %

As you can see, in terms of mathematics position UTG +1 is a "better" position than UTG by less than 15% . Thus, considering only the mathematical factors, we would have extended our range of hands played from UTG to UTG+1 by no more than 15% .

However, there is an important difference between these two positions: playing from UTG +1, we will be on average one and a half times more likely to be in position than when UTG. This advantage is especially important in the loose aggressive tables at which the importance of the position on the flop increases significantly.

These facts allow us to expand the range to include a few easy-to- draw hands (straights, etc.) compared to UTG, and to add some hands that were not played from UTG . For me, this means AKxx hands with a suited ace and double-suited AQxx.

The rest of the drawing hands UTG +1 are little different from the first position in the game - so I will not dwell on each of the previously-discussed types of hands .

A fundamentally important issue which it is appropriate to highlight in this chapter is the distribution of hand ranges according to positions. Obviously, thinking players will not play 20 percent of hands UTG, and in the small blind. But how exactly should be different hands be played in different positions?

Here, the key (in addition to one's natural style of play and personal views about the power and convenience of drawing hands) is the structure of the table. The tighter and quieter the table is — the smaller the difference is and the likelihood of the opponent showing a good hand is closer to mathematical odds. For UTG and UTG +1 , the difference is about 13 % (see the result of the calculations in the beginning of this chapter) , that is, if we play with the top 10% hands UTG, then in UTG +1 we shall play the top 11-12%.

If the table is loose and aggressive, this difference increases due to the growing role of position of the flop. The higher the opponents' percentage of bets and three-bets on the flop, the stronger the different ranges will be.

For example, my game ranges from UTG and UTG +1 at a tight table are 11% and 13% of hands and for loose 10% and 14%.
