As it says on Ed's page, the trick with this position is to keep searching checking moves in the qsearch if you find that there is only 1-2 legal replies to check in the previous ply. I read Ed's page a while ago and played with this position. Yes, you can solve it instantly. However my search got weaker as a whole when I allowed such long checking sequences in qsearch and I reluctantly bounded the depth to which I would allow checks in the qsearch. I also inserted some other sanity tests to make sure the checking side is not just wasting time running the other king around the board. Scott
