There are many ways to make a 2 card system(2cis). The most direct approach is 2652 pegs (52x51). Till Alex Mullen won the world fastest card memorizing competition, BLOCK METHOD(BM) is said to be the most efficient 2cis. However, it is not the end of making a 2cis, there are still many things can be improved.Below is an alternative to make a 2cis which I called Antelex system (AS).
It is obvious to tell making less pegs means faster reflection of instantaneous images recalling time(IIRT). Besides, less practing time to remember all the pegs.So, the question is how to make less pegs but still one could approach to 2cis?
In the past, we use person, action and object(PAO) in which a combo deals with 3 cards.Although many good players proved it is great system e.g.Shijir-Erdene Bat-Enkh,
it has a defect that some action does not match with the object or person. How if one uses BM , sometimes it holds too many same color cards.Surely, nothing is perfect,
So as AS.
