How it works
A 2/3 system on picks A, B, C places three separate doubles: AB, AC, BC — the stake splits equally between them. If all three win, all doubles pay; if one loses, one double still lands. Compared with a straight treble you win less but survive a single miss.
System vs accumulator
The accumulator is all-or-nothing with the biggest payout; the system trades payout for resilience. The margin cost per combination is the same — a system does not remove the bookmaker's edge, only reshapes the variance.
