I agree the first and second sentences with the proviso that the opponent might also admit the move was illegal but not the third sentence.Roger de Coverly wrote:The threshold for awarding a win by illegal move is relatively high. The illegal move has to be observed by the arbiter or a valid claim made by the offended player. As with repetitions and 50 move counts, it has to be the offended player to move with the clock running.
The player claiming 3 move repetition does not need to have his own clock running ( ie the opponents move completed); it is only necessary for the opponent to have made their last move on the board. For 50 move claims it is only 9.3.b which requires the players clock to be running.
Of course there is a minor flaw in the FIDE Laws for repetition and 50 move claims, which I will send to the RTRC when I am satisfied that Stewart Reuben correctly communicated the other 3 that I recently sent via this forum.
