Here’s how you make money playing chess. Follow the tips given and take home some cash. 
Just remember what they did to Paul Newman in “The Hustler”.
Note the non-button Cronos. If you’re used to hitting the clock with your hand holding a piece after a capture, you’ll likely not stop your clock. The lost seconds can haunt you if you’re not accustomed to playing blitz with that type of clock.
Such behavior is rude, because it damages the fine wood pieces that your opponent brought for you two to complete with.
Which is not to deny that such behavior occurs.
It’s not a large adjustment from using a piece to using the fat part of your palm (bottom of your fist, basically).
If you’re hustling I’d seriously doubt you’re using “fine wood pieces.”
You play blitz chess with fine wood pieces? The horror!
If you are a good chess hustler, you can afford to play with fine wood pieces 
Most of these hustler stories crack me up. These guys are about 1600 to 1800 strength. They play fast, talk trash to try to rattle players, bang pieces, and play novice players. The one thing they are good at is getting out of games. Once they see they are up against a stronger player, they quit fast. They don’t even bother to ask for time odds. They are not looking for a challenge, just a few quick bucks from some rubes.
Old trick used in Washington Square Park. I lost a won game that way. At least we laughed when the guy admitted that’s why he used that type of Cronos.
I think you are right on!
