The Grand Chess Tree

Perft 13 is complete!

Very well done - a combined effort that is well worthy of praise!

I've just started a new job so time is split between that and my 2yo at the moment, with depth 14 needing a change in architecture I'm struggling to find the time right now, I'm wondering if there are any engine devs interested in joining the project?

You should definitely prioritise your new job and your toddler. "The Grand Chess Tree" is a good project, but it's not something you'll look back on in the future and wish you'd spent more time on.

There is quite a bit of work necessary before we move on to depth 14, and as I've just started a new job I expect it to take a little while before we're ready. But once we start I estimate it to take around a month to compute with current resources.

I hope everything is fine.

I want to raise a little warning in the website: while the post I am replying to says "nodes":1981066775000396239, as in CPW (some breakdowns available here and here), The Grand Chess Tree website currently shows 1.981.066.775.000.396.288 nodes, which is 49 off. Other statistics do not match between the post and the website, at least the next three: captures, direct checks and total checks.

Regards from Spain.
