41-year-old IM Renier Castellanos had all but given up on earning the Grandmaster title. His life was getting busier, and after 2 potential GM norms were not ratified by FIDE, he felt like it just wasn\u2019t meant to be. But his friends and Killer Chess Training co-workers, GM Jacob Aagaard and Kallia Kleisarchaki, convinced him to keep trying. It turned out that was all it took! Two weeks ago, Renier got his final GM norm, to earn the title of Grandmaster at age 41. In our interview, Renier reflects on the lessons he has learned, and why he thinks he was still able to earn the title in this challenging era, despite not working on chess as much as he did in his 20s. Renier also shares his own advice on chess improvement, some book recommendations, and discusses what he observed from facing Super GM level players like GM Vladimir Fedoseev. This interview was conducted while the Candidates was still ongoing, but you can even hear Renier\u2019s Candidates prediction to see how it played out.
