it makes no difference how SOMEBODY else plays
its a 8 deck shoe, every card in itself is a statistical challenge, REGARDLESS of how other people play around you.
That's when blackjack becomes a problem, when you believe in all the little theories of how "good shoes and bad shoes come in pairs", or "you lost because of the guy before you". Give me a break
play your own cards, it makes NO difference how many people are sitting down, how stupid they play, if they double when they have a 20 and the dealer is showing a 6 or not.
The only way to win is for YOU to play strictly by the book, and not let any feelings and emotions get involved. The game is pure statistics and odds, nothing else to do with anything else.
