In fact the opponent didn't even try very hard to force Craftys king to the corner - it just went there. I expect the numbers of lost positions to be higher when the defending king has been driven to the final rank or a corner of the chessboard. Of course with 6-men tablebases this is no problem but I dont expect them to become very common soon as they are so big. Thanks for the tablebase information posted.
