I tend to agree with some of the points psted but also disagree with most of the points.

Two bets has some idea of what he is talking about but is generalising regarding systems. I can give you form factors that make a profit on their own over thousands of bets but they are not the form factors most people use. Read the probability thread a few days back and you will see what I mean regarding form factors which enhance strike rate and those that enhance profit.

The types of races you focus on are going to depend on your skillset and where you make your profits. It might be maidens, it might be group 1s, it might be set weights or it might be open handicaps. The answer is it depends.

Nearly all races have some angle that can be exploited if studied hard enough.
