1. old non-check version
2. new qsearch check version, everything else the same
3. new qsearch check version with null-move R=3 rather than the adaptive 2-3 I have been using for many years.
I am looking for a reasonable number of test positions to see how this behaves tactically. I have tried WAC but have no luck. Crafty gets all but a couple in 1 second per move. At .5 seconds per move it is hardly worse. And at that time resolution, the "jitter" becomes an issue. I'd like to have a set that the normal crafty might get 50 out of 100 at something reasonable like 10-15 seconds per move, so that I can determine if either of the new versions solves more in the same time limit, or solves the same 50 but in less time.
Anybody have any favorites that do not have all these "easy for today's programs" positions that need a fraction of a second to find? And no, no Nolot positions as I'd like to experiment and get answers back more quickly than a day per position.
