Re: Critter 1.0 64-bit SSE4 getting the most out of my Cpu

That is helpful. I have something interesting to add: A lot chess engine enthusiasts like myself overclock. It is a pain to get stable, but the results are noticeable. It is easy to point to nps or benchmark gainsfor evidence of overclocking helping engine performance, but playing results are more i...

Re: Critter 1.0 64-bit SSE4 getting the most out of my Cpu

Thanks for the clarification. I was about to edit my post before I saw the reply. It would have been more appropriate to simply ask why Critter needs additional voltage, rather than claim it gets more out of my chip.

Critter 1.0 64-bit SSE4 getting the most out of my Cpu

I thought the members and especially Richard Vida, would find this interesting: My Pc is built around an i7-920. I just fixed my cooling system and overclocked it to 4.1 GHZ. In order to prevent overheating the cores, I want to use the least amount of voltage that is necessary for the overclock. The...

Re: ATM censorship has been relaxed on Rybka forum.

It could mean ass to mouth. I was hoping that was not the intended meaning.

Zappa and mate Extensions

Zappa Mexico II comes with a Mate Extensions uci option, however, it is disabled by default. Why is it disabled by default? In what situations would it be benefical to enable it?

Re: Brilliant sacrifice (test position)

Maybe not brilliant, but it is better than Nb1. After more than 8.5 hours, Naum 4.2 still thinks Nb1 is best. If I didn't need to use my pc for other stuff, I'd let Naum chew on this for a few more plies. This exercise brings up an interesting point: The Ipon rating list - http://www.inwoba.de/ has ...

I've always wondered if any engines had anything programmed in to try and take advantage of other engines time pressure. It should be easy to figure out how much time the opponnent has, based on the time control and the amount of time that it has spent. Would it ever be beneficial to play fast sharp...
