King at default settings is still good IMO, but several settings have proven to be stronger in engine competition. >(...) >It can be done, but however it is done you shouldn't expect the user wants to be >troubled with it. I didn't ever see any of the CM personality designers complaining about that they can do it :-)) actually I think the opposite: They have much fun trying to design and test those settings (probably, because they know there are good chances to really improve the defaults, unlike with most other engines). But I agree of course, that the programmer should try to find the best adjustments for every purpose, or the best compromise. I'm sure all try to do this anyway... I believe it wouldn't have been risky to default King's selectivity and king safety to higher values even if used on slower machines. But larger hash can be a bigger problem in practise. For that, some automatic adjustement would have been required if the small default size would have to be replaced (but for the computer chess experts, it's better to be able to set the desired hash size manually, anyway...)
