Two Questions to Upper Echelon Players

"Victory goes to the player who makes the next-to-last mistake."

1) Who stated this phrase and what was he all about??

2) While defending or, when you're white and playing behind the eight ball, do you think it's better to prompt for the mistake or wait for it??
