As a game, Texas Hold 'em obviously needs the application of some mathematical rules, and it is also quite clever.
In Texas Hold 'em, there is a simple and quick calculation rule, which is the 4-2 rule. First I count my cards, or I will get a winning card. For example, suppose I have T(c)9(d), and I think my opponent is A-K (A(s)K(d) when I open it). The flop is A(c)T(d)7(h). My opponent is in the lead, of course, turn to a pair of aces, but there are five cards, and the remaining two 10 and three 9s will give me the lead. In other words, I have five cards to play.
I can calculate the approximate probability of catching one of my cards in the turn or river by multiplying the number of cards played by four. In this example:
54=20%
According to these four rules, I have a 20% chance of catching a winning card on the turn or river. The actual probability of digging is 2 1.2%, and it doesn't matter if there is a slight difference.
Only the river card came, and the four methods became two methods. We say the turn is 8(c). The five cards we were looking for didn't come, but it turned our hand into two straight cards, which can be made of any J or 6. The eight cards added always give us thirteen cards. Use two rules:
132=26%
The actual percentage is 29.5%, but again, it is close enough.
If it is purely for the sake of accuracy, I added a table at the end of the book, listing the exact percentage. Look at the card on page 270.
