IMO this is a very good puzzle for slower machines, in part because any other move leaves White worse off and in part because it's solvable by most in a moderate length of time (not too easy, not too hard). Also because the various devices display a relatively wide range of solution times (Chess Tiger on a current overclocked Palm should take under 30 seconds). Chess Genius on a 41 MHz Palm takes 1:40 to prefer Rxf7 (with a small Black advantage), 3:50 to see a small White advantage, and a lot longer (I gave up after 6 minutes) to see that it gives White a big advantage. I just tested Chess Genius on an iPAQ and it solved it in about 1 second, maybe less. I can't wait until Palm switches CPUs!
