Is Steve Jacobs a reputable BJ author/researcher? I ran into a card clumping phenomenon recently and it got me looking on the internet for essays about the topic. His essay stated my concerns verbatim and I'd never heard of the guy before tonight. Granted, I am usually way off base with my "voodoo" beliefs in playing blackjack, but I'd like any input the community has about card clumping from a poor shuffle.
