With null move, if there is a beta cut off, does it favour the engine and mean a normal deeper search is not required?

I am a beginner and want to understand why null move uses alpha, beta=alpha+1. I am sure it's simple concept but I can't understand what difference this makes. An example would be useful!

Hi I am getting the above error when I try to send or reply to a private message. Please help.

@ lucasart for your information I've made quite a lot of progress and managed to do things I didn't think I could, so I won't let your opinion limit my ambitions KMA!

I'm going with a bitboard representation but not sure if bitboards and other info about board should sit within a class, struct or simply an array. If I keep creating class instances I understand that might slow the program down. I could use a struct but there seems to be advice that says info in a ...

Thanks for the reply. I found one of your pages on winboard (below) which uses minimum number of commands and looks fairly simple - so may be a starting point for me. I take it you developed this protocol?

UCI seems more popular than winboard but ...

I'm in the early stages of developing my chess engine. Is it possible to use UCI for testing during development and if so what do I need to have in place to utilize it?

Thanks

I've seen chess code where bitboards are stored as hex strings. In my programming I've just stuck to storing them in decimal UInt64 format as it seems too much work converting to and from decimal to hex in C#. Is there any particular reason why you'd want to store bitboards in hex form despite ...

How long can it take to find a magic? I reckon I've tried a few hundred thousand randoms so far and still no luck! Someone told me they went through millions until they found magic numbers.

I tried a large array of random instances, which produces candidate magics for a while but even that approach starts producing duplicate random numbers every time after a while. Does this happen in Java, C etc?
