Chess offered those benefits to Lenderman. Famous chess coach Bruce Pandolfini talked about Lenderman and his high-school teammates to Weinreb for his book about the players. Pandolfini pondered their professional future: “Their lives have already been made much better. They’re already better problem-solvers. They’re already tougher mentally. They’re already more creative. They have more things to draw on to get them through the difficulties in life. The benefit will last for the rest of their lives.”

Chess also led Lenderman, whose family is Jewish, into a community that eventually led him to the Christian faith. But that took time as he navigated the all-consuming elite chess world. As a teenager, Lenderman was on the cover of Chess Life magazine for being one of the few young Americans to win the gold medal at the World Youth Chess Championship. 

Lenderman racked up championships, but he says he also treated the people around him badly, and he didn’t know God. Weinreb’s book chronicles some of Lenderman’s petulant teenage behavior: shouting at his father after a tough loss and accusing his opponent of cheating.

“I was always not an easy person to deal with,” he says now. That changed over time as he became a Christian, with mentoring from another chess grandmaster: “I needed to grow spiritually as well and learn how to deal with struggles.”

George Kacheishvili, a laid-back grandmaster who also calls New York home, got to know Lenderman at a pivotal moment in his young career after high school. Lenderman felt he was in a slump, like a .300 hitter in baseball dropping to .250, he said. Other coaches weren’t helping. Kacheishvili and Lenderman played against each other in a tournament, and soon Kacheishvili was coaching Lenderman.

“The way he looked at the game of chess is something I’ve never seen before,” said Lenderman. But there was something else: “Something about him was different, just the way he talked to me and everything about him … it felt like he really cared about me.” 

Kacheishvili told Lenderman he should be able to make grandmaster “very easily,” which Lenderman had a hard time believing. But because Kacheishvili believed it, Lenderman began to believe it. At 21, he became a grandmaster. 

He also began losing better, instead of giving up in frustration. During one tournament, when he was already doing badly, he says, he decided to play a meaningless game “as if it’s going to be a million-dollar game.” For the next year he played well, and gained 100 rating points—a big leap forward.

One day Kacheishvili was complaining about some ailment, and Lenderman suggested reiki—a form of New Age healing. Kacheishvili dismissed reiki with a laugh, and said God would take care of him. Lenderman was surprised that Kacheishvili believed in God. 

“My grandpa always told me people who believe in God are people who are not educated,” said Lenderman. “To me Giorgi [the non-Americanized spelling of Kacheishvili’s first name] seemed like a very normal, reasonable person, not someone who just is completely oblivious to everything. And so I asked Giorgi, ‘Do you believe in God?’ And he says, ‘Yes, of course. Only … silly people don’t believe in God.’”

Lenderman began memorizing the Lord’s Prayer, and after he explored Jesus and concepts like sin, he asked to be baptized in the Russian Orthodox Church. He uses an email address with “33” in it to identify with the traditional year for Jesus’ death and resurrection. 

Lenderman’s atheist grandfather in Germany, the one who taught him chess, has tried to convince Lenderman he’s wrong about his new faith ever since his conversion. Lenderman’s other set of grandparents are Russian Orthodox Jewish immigrants to New York. He’s hesitant to go into much detail, but his conversion was hard for his family to swallow initially, though they’re more accepting now.

On a typical day in Brooklyn, where he lives with his parents and near his grandparents, Lenderman coaches some individual chess students (making at least $150 an hour) and then studies chess for hours. He also trains in karate, because he thinks exercise is essential for professional chess players, given that they often have to play grueling games that can go for 10 hours. He uses two old laptops to study chess—one is a backup computer if the other one fails. 

This fall, as he contemplates a life beyond chess, Lenderman plans to leave the Russian-Jewish neighborhood where he has lived his whole life. He will move to St. Louis and attend college at Webster University, studying data analytics. He wants the degree in order to have career options that may come with stable health insurance and enable him to work less as a coach to make ends meet.

He’s going from New York, the old center of the U.S. chess world, to St. Louis, an emerging center. Wesley So, one of the top American players (and also a Christian), went to Webster, and other top players like Fabiano Caruana, No. 2 in the world, are based there. 

Lenderman hopes to improve his chess under the tutelage of world champions like Susan Polgár: “My goal is to try to realize my maximum potential, my God-given talent, which is chess.”

He also wants to grow socially. His two main grandmaster friends in New York, seven-time U.S. women’s champion Irina Krush and Kacheishvili, are very busy. Maybe he’ll make some more friends or meet a girl.

“I want to stay a virgin before I marry, but at the same time, I feel like maybe the fact that I’m almost 30 and I’ve never even dated, that’s also a little too extreme,” Lenderman said. “I just want to get out there in terms of social life. That doesn’t mean I should be staying out till 1:00, drinking. … I don’t like party life. But at the same time … I need to get out of my comfort zone a little bit and prepare myself for life.”

Elite chess sometimes temporarily delays a dating life, a dynamic that top players like Magnus Carlsen and Caruana have publicly discussed. 

But Jerald Times, the chess director in New York, has worked to show that chess is for everyone, the jocks and the geeks. He has taught in low-income schools, at the elite Dalton School in Manhattan, and in South Africa—and there’s one question he always hears from students: “Is chess for nerds?”

For Times, a key to answering that question is to focus on getting students into official tournaments, which makes chess more of a sport in students’ minds. It’s also where students gain the actual skills touted in so many studies: the burn of competition, the desire to improvise, and the yearning to gain status as a player. 

“Abstract reasoning, calculation, delayed gratification—those skills are gained inside of the tournament hall,” Times said. 

And that’s where Alex Lenderman feels most at home, even as he goes back to school.
