You're right. I should, and will do this.
I believe he means WSOP bracelet events by "this summer", and obviously doesn't mean only bracelets after June 21. But you raise good points here and I will check this out.
Actually maybe it's better
not to contact DN about this? If he clearly stated "summer" already and is unintentionally limiting himself to events dated 6/21 or later, wouldn't that make it a much more juicy +EV bet for the "anti-" crowd?
I'd actually be slightly tempted to stay quiet given this ambiguity actually seems to work in the "anti-DN/Ivey" favor.
Aren't prop bettors responsible for their own mistakes?
