Let's say I have 10$ and decide to play 0,10 buy-ins, that gives me 100 times the chance to win money with my chosen buy-in level. It doesn't matter from a BRM point of view, whether you play 100 at once or 1 alone. You will have to cash/win anyway in at most 50 games (last ´paid place, assuming it doubles up your buy-in) The point is, that you should play at your most confident stage of skills. You tilt, or play drunk, bad idea!! BRM should be played sober, or you will have to check up next day, where your money has gone.
I play on 4 sites and never open more than one of my chosen games at each site, so 4 tables at once. I finish one game, i open another, might be a second one of a site where i'm already playing or a new one on the site I just went out. 4 tables because of my shabby laptop, once I'll have my monitor back, I will be back to 6 games at once.
