English As we have already answered above, if a player hits the middle, they receive winnings on both bets, that is, a very noticeable “plus.” If they do not hit it, the winnings will be on only one of the bets.
A positive middle means that the player will have a profit in any case, even if the winnings come from only one bet. In practice, there are very few such middles, and they are narrow, so sometimes it makes no sense to pursue their positive nature specifically.
A negative middle means that if the player misses the middle and wins only one bet, they will incur a small loss. Those who want to increase the middle do this, thereby increasing the probability of winning on both bets and offsetting possible losses.
