Basic endgames

Pfft. It shouldn't get more complicated. Already took too much time. Only counts distance from corner and distance between kings. Maybe hash table needs to be rewritten for it does not take symmetry into account? O wait I see I introduced a bug. To be provided. [d] 4k3/8/8/R7/4K3/8/8/8 w - - Depth V...

Re: The Busted Dutch

General rule is that you must have a good reason to push a pawn from fourth to fifth line for it may easily become weak and a pawn cannot retreat.

Dutch opening was introduced by a French person who migrated to Holland. So not really Dutch.

Re: How to stop monitoring PV's ?

Maybe I will post a new video on YouTube to show monitoring PV's using signalR on .net core. In the meantime: Just using stupid Skipper library producing crap PV's as usual. Even formatting does not work. So have to fix that first. (Seconds must be centiseconds I guess) Depth Value Time(seconds) No...

Re: How to stop monitoring PV's ?

Hi hi hi. Maybe an idea is create a livestream on YouTube titled 'Solving Chess' showing process of finding PV for initial position.
Maybe run livestream every day and see how many viewers you get. Or has this already been done.

Re: How to stop monitoring PV's ?

Maybe I will post a new video on YouTube to show monitoring PV's using signalR on .net core. Or perhaps post some code. But I hacked it together for I was only interested in 'proof of concept' and it all took too much time. Even signalR exercise on microsoft website for .net core 2.2 missed an impor...

Re: How to stop monitoring PV's ?

Client or clients are browsers. Hub runs on internet information server. Maybe I better switch to WPF. For only 'stupid' or non-interesting applications run on internet. How can a server search for best moves for chess positions for many clients simultaneously. Server is not capable to do that. Or i...

Re: How to stop monitoring PV's ?

Maybe Hub has no problems with storing static data. In that case I store these cancelation token (source)s as static data and problem solved.
Although ugly solution as well if it works.

How to stop monitoring PV's ?

Client is using a Hub for monitoring pv's generated. But Hub is unable to store state. So how can a client stop monitoring. In the past I used database to store state but is there no better solution. Using a database is ugly. Hub can access client. Client can access hub. But cancellationToken is loc...
