I treat complaints as confidential, and was not planning on changing this policy. People must not feel impaired by fear for petty harrassment in retaliation for flagging wrong-doing. By the nature of things it are the most aggressve and viscious members that violate rules, and have a tendency to bu...

As a note, I just checked the position above. I ran with sd=4 (4 ply max depth) and no endgame tables at all. Crafty forced mate easily. If you don't limit the search to 4 plies it will find a mate in 7 instantly so it needs some help to make it rely just on the PSQ stuff I mentioned. Works well...

I installed this yesterday. And at least for compiling crafty (using profile-guided optimizations as well) it worked flawlessly. This on a 2017-ish MacBook air.

same as my other suggestion. PSQ for losing side hates the edge of the board. Winning side wants to get king close to losing king. The rook will automatically do the right thing to hem the king on the edge of the board and keep it there, thanks to the losing side's PSQ hating the edge. Those two sim...

Pfft. It shouldn't get more complicated. Already took too much time. Only counts distance from corner and distance between kings. Maybe hash table needs to be rewritten for it does not take symmetry into account? O wait I see I introduced a bug. To be provided. [d] 4k3/8/8/R7/4K3/8/8/8 w - - Depth ...

There is still a problem, however. Works fine for unix-based systems. Still working on the windows version. Think I have it fixed in the source I sent you today, will wait for Joshua to confirm..

That's the big question. I'm not a windows user, and I am not doing these compiles. Can you give me any hints to pass on to Joshua as to what exactly is needed to indicate "this is a 64 bit application"???

OK, we are still mucking around with this. Joshua is compiling using the latest MSVC stuff. Here's our problem (I don't have a windows box to try this on so am getting compile help.) We can access __popcnt() with no problems including intrin.h. but we can NOT access __popcnt64(). Apparently the comp...

Mike:

Still working on this. Send me the email you are using and I will send the source code once I finish this cleanup...
