What is "karshi"

Karshi (foaled 7 April 1990) was a British Thoroughbred racehorse best known for his performances in National Hunt racing. He was a moderate performer on the flat, winning one minor event in eleven attempts, but showed improved form when tried over hurdles despite recurring injury problems. In his first season over obstacles he won two novice races and finished third in the Sun Alliance Novices' Hurdle. In the following season he won the Lonesome Glory Hurdle and recorded his most important victory when winning the Stayers' Hurdle at odds of 20/1. He also produced several good performances under big weights in handicap races and won his only race over fences before leg injuries ended his racing career.
