I had a small problem with this idea though. Although my program with the K+R would successfully chase the opponents king away from the centre of the board and chase it towards the corner. The problem then was it would not finish off the job because my program didn't like to move its own king too far away from the centre of the board. So my program would do it's best to corner the opponents king with the rook while at the same time keeping its own king near the centre, this of course does not lead to mate. But as I said earlier, this is not a big problem because once you have the opponents king almost cornered it is only a few ply’s away from being checkmated. This issue only showed up when I had my program limited to 1 or 2 ply’s search depth. >If your engine has only 1300 then I think that it has big problems in it's >search or bugs that you should correct before thinking about better evaluation. He wouldn't be able to call it Little Thought if it had a better rating! Cheers, Tom.
