Gap concept in Texas Holdem
In Texas Holdem strategy, the gap concept states that you need a better hand to act against a player who had already opened the betting or raised, than you’d need if you’d open the betting yourself. That means that the gap concept reflects behavior of the majority of players, who prefer to avoid open confrontations with their opponents that already displayed strength. Proceeding from this, the gap concept states that calling only has just a single way to win – by holding the strongest cards, while opening may also result in an immediate victory in case if other players fold.
