Kibitz is a chess vocabulary term: as a spectator, making comments on a chess game that can be heard by the players. Kibitzing on a serious game while it is in progress (rather than during a post-mortem) is a serious breach of chess etiquette. Use it as vocabulary, but always ask what it changes about the position or the game situation.
