Chess was inexpensive enough—and the Russians always won until America unleashed Bobby Fischer. Vastly more expensive was the Space Race, as a proxy for scientific supremacy (with a technology with obvious military uses). As well when it came to sports the two countries both competed in the Olympics during the Cold War period which also created severe tension when the West boycotted the first Russian Olympics in 1980.
