Re: Trying to find a weird mate in 1...



Indeed, I still remember this position well for some reason too even though it was posted almost 20 years ago now. It's good to see your return to computer chess.

Re: Is my new signature legal?

Hi, Rodolfo. I enjoy playing there very much as well, and I've seen your name pop up in new tournaments. It's very clean. I also play on FICGS because the tournaments are divided by rating classes. The new tournaments on LSS are seemingly mostly filled with 700-1000 rated players who prefer not to u...

Re: World #1 Go Player Ke Jie accepts Google Alpha Go Match.

As someone who plays SCII I'm looking forward to this. Is there any hint of public availability or if it will challenge the best players? If it is allowed to control every unit individually, it will likely crush the best players. The only hope for humans at that point is to prevent scouting and exe...

Re: Thoughts on Komodo 11, Free engines and the future

One of the avenues for exploration that might become increasingly relevant would be in parallelizability. I don't know how tenable entirely shifting the paradigm away from alpha-beta to something weaker but more parallelizable is, but it very well could be on the horizon with the way hardware is pro...

Re: Position Legally Reachable?

This is a body of chess problems known as proof games, if I'm not mistaken. One example of a proof game solver is Natch . These problems are usually searching for shortest proof games, however. It will give a position and a move count asking to reconstruct the position in the given number of moves. ...

Re: Awesome lichess :-)

Is it really any good? It's easy enough to change an engine's move generator, but that doesn't necessarily give you sensible play. The most challenging variant there created from SF is atomic. All the others are easy, such as racing kings, and horde. I think they are also working on making Sf play ...

Re: The Sorcerer's Apprentice

I don't want to stop you neither Louis, but could the two of you once in a while consider to play these "games" by PM I've often worried that these "games" are an inappropriate use of the forum. For me they are easy to "play". I just relay moves to and from Stockfish, while I work at other activiti...

Re: The future shift

[D] 8/8/4k3/4r3/4R3/4K3/8/8 w - - How long for your silly, inept engines to evaluate this position as clearly won for White? We'll play it out until Stockfish can see the obvious. Make sure you let it analyze for as long as you can. My first move is 1. Rxe5. [D] 8/8/4k3/4R3/8/4K3/8/8 b - - As you ca...

A tough test position?

From this blog post about engines and deep tactics:

[D] r1b2rk1/1p3qpp/3b4/p1p1p3/2PpPpn1/3P2PP/PPNB1PB1/1R1Q1RK1 b - - 0 1

1... f3! 2.hxg4 Bxg4 3.Bh1 Qh5 -+

This position has so far proved resistant to my engines/hardware/luck. Hopefully it could be a decent challenge for others.

Re: Nakamura vs Stockfish, public match 8/23

The titled-player commentators are calling out computer engine programmers saying that they have taken too much credit in their creations' strength over humans when it's mostly been the inexorable progress of hardware speed. They're making fun of Stockfish's moves and evaluations during this King's ...
