What is the probability that Hans Niemann obtained a leak of Magnus Carlsen's prep prior to their September 4 chess game in the Sinquefield Cup? (Any means of obtaining a leak would count here.)

If conclusive evidence emerges, resolves to YES if he did obtain a leak or NO if he did not. Otherwise, resolves to market probability at the time of close.

The market close time will be quasi-randomly extended if there is still ongoing trading activity; using a procedure similar to that described in 

https://manifold.markets/MartinRandall/is-the-sky-blue-resolves-to-mkt

. The close time will be no earlier than 10/15 and no later than 10/30.

(The intent is if the market collectively decides for example 25% chance that he obtained a leak based on the available evidence, then this market should end up at about 25%.)
