King and Queen/Rook vs. King

Is it possible to set up a three piece position with;
a) White King + White Queen vs. Black King, so that forced mate is MORE than 8 moves?
b) White King + White Rook vs. Black King, so that forced mate is MORE than 15 moves?

Regards, Paul

White to move, mate in 9.


White to move, mate in 16.


(According to Shredder's endgame tablebase anyway...)

I'm pretty sure there is a website containing such information

Indeed. 🙂 Here is one example...

So the stipulation for K+Q vs. K should be different, more than 9...

The title of this thread made me think this thread was going to be about how to win with king and queen vs rook and king.

I usually just make oodles of checks and win the rook by accident.
I don`t think that works against computers but it works great in blitz vs earthlings.

I actually know the Q vs. R Philidor position, I have no life 😞
