Re: WCCC 2007

Reread the charter, there's no such thing in it :twisted: Tony It must have been 'conveniently' rewritten then. It has become the European championship, in reality. Not that strong North American programs stay away in total, just that most of them do. It would make sense to me to rotate by continen...

Re: SEE on non-capture moves in main search

I have never seen that kind of result with MVV/LVA vs SEE. You can find old discussions on this topic on r.g.c.c back in the early 90's. I ran a bunch of tests and even distributed a version of Crafty where one could choose between SEE and MVV/LVA for q-search move ordering, and others ran lots of ...

Re: Kibitz score reporting in server play

The idea of displaying a score from the program's perspective is more confusing and after a couple of years, most people decided that they liked the way Crafty displays scores. If you don't do it like this, how do you "annotate" a game with meaningful scores??? Because server play with one or two p...

Re: Kibitz score reporting in server play

How should position evaluation scores be reported when kibitzing in server play? I like the idea of a score that reflects the position -- negative scores good for Black, positive for White. For display purposes, I like the assumption that a pawn is roughly equal to 1, understanding that internal re...

Re: SEE on non-capture moves in main search

I think the problem is this: with things like hash moves, good captures, killers, etc, by the time you have tried all of those, either you have already failed high, or you are never going to fail high at this position. Perhaps, but if it were as simple as this, wouldn't the use of history counters ...

I think the problem is this: with things like hash moves, good captures, killers, etc, by the time you have tried all of those, either you have already failed high, or you are never going to fail high at this position. In the so-called ALL positions, ordering is irrelevant anyway, and wasting comput...

Re: WCCC 2007

you know as much as I do about that... I might begin to play in the CCT type events and not bother with the WCCC. It takes too much time. Costs too much. Has just a handful of participants each year. CCTs are more fun competition-wise...

Re: WCCC 2007

You do have to be an ICGA member to participate... but it is not horribly expensive to join. It just costs a small fortune to attend an event that is a long way away and which lasts for almost 2 weeks including travel time.

Re: WCCC 2007

It was modified a few years ago after I kept pointing out the problem. Rather than do what the charter said, they made the charter say what they do.

Re: WCCC 2007

The lateness isn't a surprise. But I doubt I will be able to participate. It takes time to prepare, arrange for hardware, and so forth. With no official announcement yet, it is probably too late for me...
