Hello!
I've been struggling with searching checks at qnodes for about 10 days now to determine any gain.
No joy. I've tried it with my programs as well as couple of written by others.
I had tried everything that comes in mind like:
- searching all checks after caps/proms.
- the above, including hashing in nodes that allow check search.
- different restrictive conditions - 1st qply, two qplys, 3, e.t.c., restricting by qnode counts with combination with the previous.
- I don't do it if the current position is in check - evasions search then
instead.
- Also, tried not to generate every checks, but only the discovery ones.
I'm sure I don't have any problem with the generation, because I had used my own debugging framework to determine
if there are any bugs, plus (as I said) I did it with other programs too with their own generators.
My request is if anyone have experience with elo gain related to this, please share.
Thanks!
