Why can I trust the preflop chart?
The preflop chart was developed in cooperation with different experienced professional Pot Limit Omaha poker players.
All involved professional players have studied the Omaha-Bibel "Advanced PLO Theory 2: Six-Max Strategy" by Tom Chambers which is known as THE book for professional Pot Limit Omaha players. In the poker scene is common known, that the book is way ahead of the current Omaha-knowledge.
Tom Chambers teached us, how to think about Pot Limit Omaha. This knowledge influenced the development of the Preflop Chart.
Why should I use a preflop chart?
A preflop chart allows advanced and professional players to draw a changeable preflop strategy. If the player doesn't exactly know his preflop strategy, he can't make proper changes to different part of his preflop plan.
For a beginners a preflop chart helps a lot in learning a solid preflop strategy without having to learn the very complex stratetical background.
Isn't the chart to general?
The "Standardstrategy" is the average of all preflop plays. In some situations against fishes you should probably raise some hands which are recommended to fold while in other situations against tough players you should fold hands which are recommended to raise.
If you don't know what hands to play or play against unknown players, you should stick to the "Standardstrategy".
For what game was the "Standardstrategy" developed?
Pot Limit Omaha 100bb deep. But it's recommendations are generally also applicable to other stack sizes. There might have to be made some adjustments like always 3-betting AA** when very short or 3-betting less from Out Of Position when very deep. In some plans you can also adjust the strategy to your specific needs.
How does the preflop chart work technically?
Omaha hands are very different in their characteristics.
You can say that 9865 is the better hand than 7653 while it is very hard to directly compare KK72 rainbow to T976 single suited. KK72 rainbow has better preflop equity but has basically no postflop playability. The hands are very different and should be treated differently.
In the preflop chart, all Omaha hands are divided into 45 different hand categories. Within a hand category the hands are comparable to each other.
All hands were ranked separately within each suit of each hand category. For each play in each hand category and each suit, there is a borderline hand selected. All worse hands of the same suit and in the same hand category are not recommended to play while all better hands (and the hand itself) are recommended to play.
Summed up, each preflop chart is a combination of over 1800 different settings.
