BEIJING — Curling is often called chess on ice. Thursday night, it was more like a math problem on ice for John Shuster and his teammates.
The U.S. men trailed Great Britain 5-4 after five ends in an Olympic semifinal. In the sixth end, Shuster had a chance to score only one point, so he threw away his last stone to retain control of the hammer, the final shot of the end. The strategy was to keep control of the hammer until Team Shuster could set up an opportunity for multiple points.
The seventh end played out the same way. So did the eighth. Finally, the Brits' precision backed Team Shuster into a corner it couldn't escape, handing Great Britain an 8-4 victory and ending the United States' chances of repeating as Olympic champion.
Shuster's Duluth-based team will play Canada for the bronze medal at 12:05 a.m. Friday (Minnesota time). Great Britain skip Bruce Mouat will lead his foursome into Saturday's gold medal match against Sweden, a 5-3 winner over the Canadians in the other semifinal at National Aquatic Centre.
After a beauty of a shot by Mouat in the ninth end, Shuster made an analytics-based choice to throw his last rock through the house, conceding a point to the Brits but retaining the hammer for the final end. Down 6-4, Shuster said the odds favored his team's chances of scoring three points for the victory.
The strategy was sound, but the execution faltered.
"Everybody dreams of coming to the Olympics and winning a gold medal,'' said Shuster, who will play for his third medal in five Winter Games appearances. "You lose the semifinal, and that dream ends.
"But I've also been part of a team that's lost this game and had to come back and play for a bronze. And I knew exactly how we handled it to get ourselves ready to come and win that bronze. If we play great (Friday), we'll see what happens.''
