Baard compared curling to chess—and deal-making—because "you make an offer anticipating what your competitor is going to do. And you're also making yourself ready to make a counter to your opponent's counters."
Sanjay Nath, who grew up playing competitive chess and works as director of the Institute for Graduate Clinical Psychology at Widener University, agreed with Baard. Wall Streeters "want to watch the market and anticipate what's going to happen, and they want to do that before their peers do," he said. "You get the same thing in curling."

The ability to determine probabilities is a skill that's critical in both settings as well, Nath said. Curlers try to close with as many points as possible when they deliver the "hammer," or the final stone that marks the actual physical execution of the strategy the team has been building toward.
"It's about abstract reasoning—can you think on your feet and get to the next step?" he said. "But you're also wanting to see the chances of whether they'll technically be able to do it or not."
Some Wall Streeters have also taken notice of the same odds-making possibilities that curling offers.
Raj Mahal, a former trader at Bank of America, told CNBC that he required junior traders to handicap curling teams during the last Winter Games, in Vancouver in 2010.
"I would take five or six junior traders and say, 'OK, you have three minutes. Come up with a betting line,'" he said. "It was an exercise to see how their minds worked and how they handicapped when they didn't know anything at first about how the game worked."
"After the third or fourth time, the splits were coming in pretty similar," Mahal added. "So I could see they were getting better at it."

The BofA traders examined how teams had performed in previous match-ups and then extrapolated that data to set odds on future outcomes, Mahal said.
"Honestly, I had no idea what the real odds were," Mahal said. "Then surprisingly, when I back-tested the traders, they were pretty close."
Canada, Great Britain, China and Sweden will play for the men's curling finals on CNBC on Friday at 8:30 am ET.
