Because I think there is something to be said about the "quality" of play. To expand slightly, the dealer made four 20's prior to the BJ's (all ten cards) while I got seven stiffs and a a 17. Think it was time to find something else to do for awhile. BTW, when one speaks of "variance" is it in the cards, with the dealer, with the player or casino ?? I'm asking because there have been many times where I switched tables, or the dealer where I'm playing is changed, and I go on a mini win streak (maybe 5-7 hands in a row) which put me solidly back in the plus category. Maybe not immediately, but within a couple of minutes of the change. TIA
