I have put together a test suite of positions from games Arasan has played, mostly on FICS or ICS. I posted an earlier version of this some time ago but since then I have removed some easy positions and ones without clear solutions, added some new positions, and tried to carefully verify solutions for the ones that are in the suite. The latest version is given below. I usually run this test at 60 seconds per move and Arasan is presently scoring about 56 out of 90 correct on a K6-2/400 using 16MB hash. I would welcome feedback, especially if you think any of the solutions are incorrect (note: a few are quite difficult and will take most programs much longer than 60s to solve). The positions are also available on my website http://www.best.com/~jdart/arasan.htm (see the link near the end of the page). --Jon 3r1rk1/Q4ppp/6q1/4n3/8/4P1P1/1P1B1P1P/2R2RK1 w - - am Bb4; id "arasan.1";
