It was suggested to me that I not risk more than 10% of my bankroll in any given day while playing SNGs. This is also my rule of thumb for cash games, although I seldom let it get even that bad before calling it a day. Since I am starting w/ $1k that would mean $100 limit to start out, leaving me with a possibility of playing only two separate $50+2.50 heads up SNGs. Is this too restrictive given my schedule outlining how I'll be moving up or down? Any modifications to the 10% rule for exclusively playing HU SNGs?
