Its Martingale, if he loses he chases his losses plus a predetermined amount he is trying to profit. It used to be if he loses 7 legs then he would be done chasing, but recently he went down like 4 legs and he said he would stop if he loses 5 legs. I dont follow him but there are alot of people on this forum that do and go crazy if one of his picks do bad on any particular day.What's Ace's system? If he loses the first pick he makes another for double the money?
