HIARCS Chess Forums

Here's a new wrinkle for you: I set up your position on my MacBook running Sigma Chess HIARCS 12.1 MP. It insisted, even after a full minute, that White's next move should be: 1. exe4 which, of course, is totally impossible. Then I switched engines to the relatively weaker Sigma 6.1 engine, and it f...

. . . currently is being beta-tested. It will be UCI, and therefore HIARCS, compatible. :-]

Oops, sorry! Make that Elo 2950.

Thanks, Harv and Mark-

Estimated Elo 2900 on my little MacBook. Amazing!

Hey, Krazyken- Wondering if you have found any tricks to optimizing Sigma Chess HIARCS that I don't know about. I'm using the recommended settings on a MacBook Intel 2.2 GHz with 2GB RAM and showing an Elo of 2900. That seems great to me, but I'm always looking for some tweek I don't know about. Tha...

Hi, Harv-

Any idea when we might see Sigma Chess Hiarcs 12 MP? May? June? Thanks.

Glad to hear 12 is so well-received by the PC people. I eagerly await--but am not pushing you guys for--Sigma Chess HIARCS 12 MP. I'm not sure why, though. Version 11.2 MP already shows Elo 2980 on my equipment, which is great for analysis and almost twice what I'm rated. So . . . unless I'm into co...

Hi, Harv-

Does what you said here apply to Sigma Chess HIARCS 12 MP? Is it coming out in March, too? Basically on the same terms?

Thanks much.

Hi, Thomas- I, too, find the Sigma GUI best for most purposes. I do also own a copy of ExaChess, which is better for annotating full games because you can enter (and even play out) sideline variations from a chess book of annotated games, for example. Also, move entry is easier with ExaChess because...

Bnemais, I ran your last example wherein HIARCS allowed a passed pawn by 9...c5 and I note that HIARCS' was still in its opening book at the time. It didn't come out of book until move 19. But even when it came out of book, it didn't seem concerned. (I'm running SIGMA CHESS 6.1.5 HIARCS 11.2 MP on a...

Brilliant, Andreas!

Worked perfectly--once I started using valid FED lines. Thanks for pointing out that I hadn't been.

Thanks for the quick response, Mark. Wow! If HIARCS 11.2 MP is rated at 2890 when it's thinking at 95k n/s, I can't imagine what it must be rated when it's thinking at 440k n/s. It boggles the mind! Not that I need a higher Elo to play against--I almost never play against HIARCS--I use it on Monitor...

I tried just copying 5n2/B3K3/2p2Np1/4k3/7P/3bN1P1/2Prn1P1/1q6 w and pasting into into the game notation window of Ole's Sigma Chess 6.1.5, but it didn't work. However, when I tried the same thing with Rolf Exner's ExaChess 3.1.3, it worked perfectly. From ExaChess, it takes just a few clicks to cop...

Hello, Ted-

Sorry for such an elementary question, but would you mind telling me what you used to add the game position display to your post here? This is something I need to learn how to do.

Thanks.
