SIMPLE AS – free horse racing system

Rules:

1. Use this on any race better than class 1 races.
2. Eliminate any horse whose form figures don’t end in 12 e.g. 12, 212, 312, 412, 512, 612, 712, 812, 912 or 012 but not where the last two runs have been interspersed with a spell.
3. From the remaining contenders, back the shortest in the market and, if less than $4.90, double your normal bet.
