Fix cycle detection in presence of repetitions In master search() may incorrectly return a draw score in the following corner case: there was a 2-fold repetition during the game, and the current position can be reached by a move from a repeated one. This case is treated as an upcoming 3-fold repetition, which it is not. Here is a testcase demonstrating the issue (note that the moves after FEN are required). The input: position fen 8/8/8/8/8/8/p7/2k4K b - - 0 1 moves c1b1 h1g1 b1c1 g1h1 c1b1 h1g1 b1a1 g1h1 go movetime 1000 produces the output: [...] info depth 127 seldepth 2 multipv 1 score cp 0 [...] bestmove a1b1 saying that the game will be drawn by repetion. However the other possible move for black, Kb2, avoids repetitions and wins. The patch fixes this behavior. In particular it finds mate in 10 in the above position.
