The Adult Improver series returns to Perpetual Chess to spotlight another accomplished amateur. This week we are joined by 48-year-old data scientist, NM Matt Gross. Matt returned to tournament chess after a 17-year hiatus with a mission to earn the USCF Master title. With a 2140 rating, Matt did not need to earn so many additional points to reach his goal, but he found that the game had evolved and competition was much tougher in 2021 than in had been in  2004. Matt could no longer rely on outcalculating his opponents and playing dodgy openings, He soon realized that  he would need to revamp his entire chess game. He decided to focus on building a solid repertoire, and, most of all,to work assiduously to improve his chess intuition.  Matt’s mission to make NM took a few years, but he managed to earn the title in 2023, possibly making him one of the oldest players to earn the NM title in the past few years. Our conversation is about how he went about this.  In addition to the insights from this conversation, Matt also shares a treasure trove of advice and resources on his blog, Movelibrary.
