ChessPositionRanking VS Kirby

3. There's extra nuanced things you might want to handle in the coding, like that pawns can't be on their own back row. That is significantly harder.

It looks to me like https://github.com/tromp/ChessPositionRanking has resolved these sorts of issues, but I haven't dug into exactly how.

Multinomial rankings can be combined with a dozen others to rank a subset of all chess positions including all legal ones. This allows one to sample millions of random such positions, determine how many are legal, and thus obtain an accurate estimate of 4.8&10^44 legal chess positions [2].

The key words being "without promotion". Both bounds, this one and Steinerberger's, only consider positions reachable without promotion. Allowing promotions, one estimate suggests that the number is close to 4.82 × 10^44.

This one as well as Shannon number wiki seem to say that possible sensible moves are about 10^40 while and 10^120 while taking any moves (maybe including some illogical / illegal ones) .

Shannon's estimate was based on very primitive methods; by generating random positions and using fairly advanced methods to see whether they are legal or not (ie., can you construct a proof game for it, or prove that it could never happen), you will get much closer. A group of people have been working on this, and their current best estimate is (4.822 +- 0.028) * 10^44, or a bit over 148 bits. (Amazingly enough, Shannon wasn't all that far off on this account! His estimated number of legal games seems much more dodgy, though.)

Practically speaking, https://github.com/tromp/ChessPositionRanking gives a number between 0 and approx. 8.7 * 10^45 for any legal position, so it's only a couple of bits away from optimality.

The number of chess positions has now been estimated with 2 digits of accuracy as ~ 4.8 x 10^44: https://github.com/tromp/ChessPositionRanking

Not sure if this is what you’re after but give https://getkirby.com/ a try

Personally think https://getkirby.com is the entry to beat but I guess it’s just because I’m used to it and it works incredibly well for my use case.

Check out KirbyCMS. A PHP based files-only CMS. Can also be used as headless CMS. Works on most shared hosts and doesn't need a database. You'll have to do some basic PHP for the templates, though.

I guess it depends what you need to build. I used to use Wordpress for all my personal and client projects but I then moved to Kirby[0] and I couldn’t be happier.

But I think it highly depends on what kind of projects you work on.

I can recommend Kirby (https://getkirby.com/), a flat file PHP CMS. It’s fast, has a panel to update data and can be hosted on any basically any PHP host. Just use the quite simple PHP-templates and add CSS & JS like you already know how to do. No need to complicate things.

PHP has a lot of top tier CMSes. IMHO bunch of them are even better than Statamic. Craft CMS (https://craftcms.com/) is a lot more mature database based CMS. Kirby (https://getkirby.com/) is better at flat-file and has a lot better admin interface. Twill (https://twillcms.com/) is better integrated in Laravel and is fully open-source. Statamic mostly feels like it's sitting besides Laravel and they call themselves Laravel based for marketing.
