Chack also won one senior national medal, bronze at the 1993 U.S. Championships.^[2] After his performance was skipped by the broadcaster, his surname became part of figure skating's colloquial vocabulary, e.g. "to chack" meaning to omit a good performance from a television broadcast.

Chack withdrew from the 1994 U.S. Championships due to a groin pull and a stress fracture in his right leg.^[3] He was coached by Peter Burrows for 14 years and by Frank Carroll for five years.^[4] After retiring from competition in 1999, he began touring with Holiday on Ice.^[4]
