The idea is to trap the black king with the two white rooks, but with black having enough material so that white wants a draw. For example put a couple of black rooks at f8/e8 so that there is no mate and add another black piece or two so that the computer will believe black is winning and go for the perp. > >My engine Schola doesn't report a draw score here until the repetition has >actually been played once through, though it does end up getting the draw, so I >probably need to add a similar mechanism to the one you suggest. > >Andy.
