Each date will resolve YES if I study at least 90 minutes of chess on that date, and no otherwise. My record of doing so before this month is 13/14 (92%). Chess study includes tactics, opening preparation and game study, but not online games. 

My current goal is to learn how to play a new 1. e4  repertoire, which requires about 100 - 200 hours of spaced repetition practice over a couple months. I created this market to publicly track my progress and to give more context to traders in my chess.com rating market.
