Re: Interior node recognizer and capture / stalemate

In those drawish positions that are really drawish after say the first 12 or so initial iterations show no immediate gain of material the draw detection could be turned on for deeper iterations.

Re: StockFish made a great comeback vs LCO at the End.

"Sounds very much like MC" Not really, imo. MC is random and requires millions of games to generate deep statistics to base decisions on at the root. And still at the end of that process it is a haphazard approach. It is like making a random dartboard with irregular shaped regions with random values...

Re: StockFish made a great comeback vs LCO at the End.

But of course we need at least 1000 games to make any sound judgement, since if you beat your closest friend who is close enough in rating in a 100 mere match, he probably will NOT admit of you being stronger unless you beat him in 1000 games, which could be very hard if it was physical fighting to...

Search interruption with move order adjustment

At anytime during the search the best move may not be tried first. The best move may make itself known two or more ply later when it is searched and causes a beta cut or maybe just raises alpha significantly. So let's assume that we are at the point in the search where we are making a beta cut. The ...

Re: A bug is squashing me. HELP!

I found one bug and it works better but it still is not quite right. It might be because I'm interpreting what I see in the debugger incorrectly because of fail hard therefore the scores I see are not the true score. So I'm going to switch to fail soft while debugging. However, I was able to play a ...

Re: Searching crazy positions

The caveat to that is even positions that are equal can be ridiculous or were arrived at by a ridiculous move sequence.

Re: win-chance for each root move

Back in the early 70's there was a book titled The blue book of winning chess. Or something very similar. It was a rather large book and gave the winning percentage for all opening moves for the root moves as well as for all the moves of every opening for all positions that had at least 100 games pl...

Re: Searching crazy positions

My use of the word ridiculous was probably an oversimplification. I only used that word because the positions given look that way to humans such as the original poster. I was just trying to make a point. The number 8000 was just a number that I pulled out of thin air because I do not think we know w...
