when it is behind it should learn to try to force tactically complex positions based on the same logic. behind is not only when you already expect to lose and behind can be also when the expected result is 30% or 40%. There are positions when the stronger side cannot keep the advantage and also avoi...

LC0 is weak at tactics. But it knows that, and has learned it should better avoid tactically complex positions. Conventional engines are good at tactics. But they are not aware of that. Their evaluation is just as happy in tactically quiet positions as in tactically complex ones. They never learned...

I could find the following tournament that had 100% draws except one losing player but it is not good enough because this tournament has also less than 100 games. https://www.iccf.com/event?id=66679 I do not see so far one world championship in correspondence chess with at least 99% draws The follow...

The draw rate keeps rising, and it's been years since anybody at the top even lost a game. When I started playing Freestyle,12 years ago, this was the picture: https://i.postimg.cc/pLFRNtR9/Screen-Shot-09-16-19-at-10-47-AM.png Nothing radically different, from what we can see in correspondence ches...

Heh, a 0.00 score. I actually went and tried my mainline against ChessDB and I was quite impressed about the wide coverage it already had of it. It also showed a 0.00 score. Eventually we were at a "this position doesn't exist, click here to request analysis" thing, an after 5 seconds it was still ...

I posted 5-6 answers/posts. they were regularly submitted, and now they have disappeared! They're on page 2 of the thread! When you go back to page 1, they "disappear", as they're hidden from view because there's a maximum of what the forum can show per page! Once you go to page 2, they appear, and...

I'm not following what you suggesting , but the tree is much bigger with Qxh7. I think Uri is taking the view from the player giving the mate, so the tree is the tree of possible defensive moves. To prove it really is a forced mate, you don't need to look at other moves that are possible for the ma...

Note that the mate does not have to be the shortest mate and mate in 3 with a forced line that means only 5 plies is better than mate in 2 when black has ma...
