Zap Chess Mexico?

[Spock]

IIRC, Naum 2.2 is the same way.

And Loop

[M ANSARI]

So if I simply create a UCI Zappa engine in CB GUI it will automatically play with 1 core even though 4 cores are present? Is that right? And that the only way for it to play with more cores is if you go into parameters and change that? That seems silly to say the least ... but that would also account for the 85% loss rate against Rybka on same machine.

It's not silly really, just a choice. Most engines default to the max number of CPUs. Zappa and Loop, I think Naum, and there are others, default to 1

It seems more like a silly mistake from your side.

Well - you should always open up the parameters screen anyway to check that you're happy with the defaults. Standard procedure here.

First thing I do before I play a game of my own against the engine. Of course, I lose within 30 moves but that's another part of the story.

On the contrary, defaulting to the max number of cores would be silly. Single-CPU users shouldn't be forced to make any adjustments just because they have hyperthreading.

Problem is I don't have a zappa.ini

Create an empty text file from notepad, rename it Zappa.ini and just enter the single string
threads n
where n = the number of threads: 2 for a dual, 4 for a quad for example.

Or download Zappa again, the current version comes with an ini file.

Is this current version an updated engine? And if so, should purchasers of Zappa Mexico get an email notification of this update? I haven't gotten any such notification of an update.
