OK, off topic for pool, on topic for identifying the hustler.
I was at a "black" match track, horse racing. A very few white people but since I kept my horses with a black friend and was known in the community I was welcome. It was about midmorning when an old pick-up pulled in. Mississippi plates but we weren't far from Mississippi so not surprising. The pick-up had an open box around the bed made from two by fours and a horse in the box. This was a bit unusual, there were some awful ratty trailers at that track but nobody hauled a horse in a pick-up!
Watching from the side of my eye I watched an elderly white man and his wife get out of the truck. Getting a little closer I saw he was wearing ironed khaki pants and work shirt. It was thin at the cuffs and neck but neat. I walked up to the truck staying five feet or so back. Nobbling horses was a past time here so approaching a horse too closely without an invitation was a bad idea.
The horse's coat was long and ungroomed but I noticed the racing plates on it's feet. Nothing wrong with the confirmation under that ratty hair either. The lady was nearby and she matched the man, she was in gingham dress and sunbonnet, poor but neat as a pin. Everything was a little too perfect, except the racing plates. I used barrel plates which looked like regular shoes until a horse's hoof was picked up. Aluminum racing plates were in sharp contrast to everything else presented.
A little later a friend came up and asked what I thought about matching with the old couple. "Not no but hell no!" A little later they matched up for $500, a moderately big bet, and won pretty easily.
When I got back to the farm I asked Red about them. That horse was AAA and the old couple's retirement. They knew every match track for a couple hundred miles around and never hit the same one more than once or twice a year. They liked to run for $2500 but would drop down as low as $500 rather than go home empty handed.
I don't know if I might have bitten had it not been for my years in a pool room screaming a warning but the pool rooms told me the people were laying a spread just like I had many a time in a pool room. A fine old couple and I used to pass by their farm on the highway now and then. Tempted to visit but I didn't know them. We were kindred spirits though.
