Q: My opponent is repeating moves, and preventing me from winning the game, it's not fair!

A: It is a perfectly valid strategy in chess to play for the draw, if otherwise you are faced with losing the game. It is up to you to find a way to checkmate your opponent, despite their best efforts to tie the game. There is absolutely nothing unsportsmanlike about using the threefold repetition rule (FAQ #39) or the threat of a stalemate (FAQ #37) to one's advantage.
