I am of the opinion that however someone at the table chooses to play their hand has no effect on my wins and losses in the long run.

But with this opinion, I am in a tiny minority it would seem.

I constantly hear things like "I was playing at this one table and this guy was splitting tens so I just got up and left." or "Never hit a such-and-such hand, you'll just wind up taking the dealer's bust card."

In my mind, if a guy wants to DD on a 7 or hit a 16 v 6, then in the long run it doesn't have any effect on what the next card is going to be.

Is there any credence to this popular conception that a bad player can cause the table to lose in the long run?
