Thanks for this.
Szewczyk of Poland is playing --- wow! I don't recall ever seeing him at a US-based event before.
It would be nice, not to mention shocking, if all of these showed up, for this would be a super-elite field. As you've seen the sign-up sheet, are the top Americans (Fargo 750 and up) signed up, too?
This event is right before World 10-Ball in Las vegas, and so I wouldn't take participation as some kind of buy-in of the format or the series or anything. Yes, lots of US players --SVB, Woodward, Chohan, Deuel, Styer Seaman, Sossei, Reinhols, Wolford, Olson, Robles, etc.
It is exciting that this event is scheduled to go to 256 players next year!
Szewczyk has been in US a couple of times. 2019 US Open and world 10-Ball and Diamond Las Vegas Open. Also US Open this past Sept. He also experienced the Pro Billiard Series format at PBS Austria Open
