I've often wondered how the 10 BB rule came to be. I figured there was some sort of mathematical justification. Is that correct? Or, is it just a general reluctance to risk >x% of your stack that isn't backed up entirely by numbers?

The 10x BB rule is mainly to simplify things for beginners, nothing else. Unfortunately once these beginners become non beginners, they sometimes fail to realize this.

There is a mathematical justification for it.

There is a point where if you have nBB that it is mathematically incorrect to raise and then fold to a n allin reraise.

I don't remember what the actual number is and I think 10BB is a slight overestimation, and I think it depends on your holding, but 10BB is a good number for a rule of thumb.

Does anyone have an archive link?

The Karlson-Sklansky hand rankings, although not addressing this exact problem are a look in the right general direction.
