I'm reading John Patrick's book "Blackjack for the 21s century (is this a good book to read?" And he has a very interesting yet thought-provoking chapter called "Reading Trends. He says he'll watch a table and wait for the dealer to go on a cold streak(3-4 bust cards in a row) before sitting down. Is this an accurate method? I thought it wouldn't be because the previous hands should have no effect on the future ones. Or is there some legitamacy to this approach? At no time does he mention card counting so that is out of the picture
