Non veni pacem mittere, sed gladium.
You shouldn't try to hustle people strange to you, even if you do have a two-piece, custom made pool cue -- Jim Croce
"You shouldn't try to hustle people strange to you..."That's how hustling works. People you know also know you and won't play along. I had no idea street chess was such a big scam. Police should crack down on those back alley chess games using unregulated pieces.
Policeman: "Have you registered that chess board?"
