It can be used as a guide when entering preflop trading, comparing the size of the pot and the required bet. For example, a player will make a set about 1 hand out of 8 by playing a pocket pair.

This means that if he enters into trades with small pairs, it is necessary that the bank was formed by several limpers and exceeded the rate by 8 times. This will allow you to play according to the pot odds and the bet will be profitable in the long term.

If the pot and the size of the bet do not allow you to play according to the odds, it is worth considering the stacks of your opponents. They should be of such a size that, when receiving a set, a poker player can form at the expense of an opponent such a bank that would recoup 7 losing investments in a similar situation.
