Basic Strategy question

Hi...

I'm just getting into the game of Blackjack in depth, and have found the stuff on the web very useful. But I have a question about basic strategy; do top notch players memorize each table? I realize they're all essentially the same, but do good players really know the differences between, say, 4 deck shoe games and 6 deck shoe games? Thanks...
