Yeah I'm like KV, don't want to lose bank and don't run more than one.

Thanks though Stebbo, it all contributes to getting a good feel for what I should do.

Again, Bhagwan, I like the idea of the 3.5 ratio, though I had independently set it at 4.0 (therefore lose 1/4 of bank when longest "anticipatable" losing streak is struck). Thanks for the "ready reckoner", handy to have.

Who is this Dr Z fella? And does he know how to fix my sore neck?
