Here's my scenario, White has pawns on c2 and a2 and a king on c1. Black has a queen on b4.
[fen "4k3/8/8/8/1q6/8/P1P5/2K5 b - - 0 1 "] 1...Qe1+ 2.Kb2 Qb4+ 3.Ka1 Qe1+ 4.Kb2 Qb4+.
Why isn't this threefold repetition? I'm the player with Black, we've been going back and forth for 30 moves. I've offered a draw and the guy won't accept. I have the weaker position on the board, which is why I want a draw. Is this just bad chess ethics on my part?
