assuming that one has developed a selection method that can consistently show a profit at level stakes, i do not see any point in betting in any other way.

level stakes betting is the only way i am able to maintain the integrity of my bank, as i have learnt the hard way (many, many times) that any other form of betting - increasing/decreasing/whatever after a loss or a win - is usually masking problems with my selection method & that i have been deluding myself into thinking "this works" when the opposite is true.

so if you have been clever enough to develop such a method, thank your lucky stars, bet a level stakes & enjoy!
