I can't even imagine the speed of your solution, over 1,000,000 positions/sec. on an i3. I guess I have a long way to go.

[hgm]

Fairy-Max is a minimalistic engine with virtually no evaluation. (Basically just piece values and centralization points, everything calculated incrementally.) It also doesn't sort moves, (No killer or history heuristic, no need to calculate SEE.) This is why it can have such a large node rate. The number of nodes it reports might be slightly exaggerated, though. Because it does Internal Iterative Deepening, and counts each iteration as a separate node. And it does an extra iteration just to determine the Most-Valuable Victim before it really starts to search any moves.

OTOH, the move generator is relatively slow, because it scans the entire board to find its own pieces (no piece list). But it helps that it is written in plain C, which is a fast language. It seems that a highly optimized compilation can still be about 1.7 times as fast, btw.

As far as raw speed goes: an advanced method of move generation, like I described in the "Mailbox Trials" discussion, was able to reach 8Mnps on the same machine.

OTOH, the move generator is relatively slow, because it scans the entire board to find its own pieces (no piece list). But it helps that it is written in plain C, which is a fast language. It seems that a highly optimized compilation can still be about 1.7 times as fast, btw.

As far as raw speed goes: an advanced method of move generation, like I described in the "Mailbox Trials" discussion, was able to reach 8Mnps on the same machine.

Everything you said your engine didn't have I have. Although my engine is over 500x slower, we do get the same answer. Are using bit-boards? As far as C is concerned, I recently converted from VB.NET and only got a 10% increase in speed. Perhaps I need to optimize my C#. thx for the info
