A Simple Introduction to the Sandwich Effect in Texas Hold'em
Because players in Texas Hold'em act in turn and in a fixed manner, consequences in terms of strategy are heavily decided by position. Some of these consequences are that only certain poker plays and hands that are viable in a specific position. One of the principles governing this fact is the sandwich effect.
The sandwich effect is somehow easy to understand, especially if you have read about poker strategies and played real poker. It simply states that a player who is earlier to act will need a superb hand in order to open and remain active. And conversely, an opponent to the right of a player must have a better hand than that player in order to open and remain active.
This is because the early position does not have the privilege of having information that later players will have. Pot odds, for example, could still be manipulated by players who will act later. Thus, there is an uncertainty that an early player who opens will need to match a re-raise later in the betting round, which sometimes makes for pot odds which are not good.
For example, if the player under the gun is the one to act, then they need to consider a few things if they intend to open. First, what is the probability that succeeding hands are better than theirs? Second, could their hand survive if many players become involved in the pot? Third, what pot odds could their hand afford?
If the player under the gun is holding a mid-range hand, there is only a slim chance that it could be the current best hand in the table. Also, a mid-range hand will have difficulty competing with many players, since that is no situation to bluff. And lastly, a mid-range hand could only afford minimal pot odds, since the hand is not a good bet come showdown.
The sandwich effect is the principle behind several Texas Hold'em poker plays. Bluffing, for example, takes advantage of the sandwich effect. Late position players can easily fake their hands because they know that the early players could not afford to remain active if they have vulnerable hands. Thus, a late position player could easily force earlier players to fold by playing aggressively.
The result of the sandwich effect is a simple common-sense idea: if you are in an earlier position, open or simply play a really good hand, or fold. This is the idea behind the best strategy in poker: play tight by playing only the best hands, but play aggressively. Practice playing Texas Hold'em poker and read up more strategies, and you will gain a better understanding of it with the help of the sandwich effect.
