i guess what shaun is doing is counter to what most punters would try to do.
a senior mathematician did the numbers on black and red and his conclusion was that by incrementally betting black and red you will lose the amount that the game dictates what you should lose.

in the case with horses it is going against conventional wisdom as many variables come into play such as changes in class,form, barriers, jockeys, setting for races, tracks

also it has never been proven conclusively that punters can pick winners with any degree of certainty at any time letter alone playing russian roulette with a stable of horses.

not for me i'm afraid. even if our esteemed punter does come out in front is it a fluke or luck or good management.
i would leave out the last.

i know it is none of my business but it worries me when punters attempt to do things that put so much hard earned at risk without any research, statistics, knowledge, trust, etc.
best of luck
