Hi Lord Kira,

 I agree with you. Going to the kingside and then switching with Rb1! would have been the cleanest way. 

Cheers! 

is this video a joke because when you said the game could go as follows you take a pawn when the mate move was rook b8

to stevie1965: at that time, the white was in a check position, so, he had to move his king

so funny endgame u should study more kira u wast my time
