BBC 1.0 release - UCI chess engine by CMK

[maksimKorzh]

Hey what's up guys, Code Monkey King's here.
Finally we've reached the state of the very first
release of BBC (Bit Board Chess) - a didactic chess
engine written BY NOOB and FOR NOOBS.

Release BBC 1.0: https://github.com/maksimKorzh/bbc/releases/tag/1.0
Source code: https://github.com/maksimKorzh/bbc

I was inspired by VICE series by Bluefever Software
but when I just started it was a rocket science to me)
So I've decided to make something similar, but using
the easiest C programming language's pattern possible.

BBC's page on CPW: https://www.chessprogramming.org/BBC
YouTube series (82 videos): https://www.youtube.com/watch?v=QUNP-Uj ... wfiWNI76Cs

Features

- bitboard board representation
- pre-calculated attack tables
- magic bitboards for sliding pieces
- encoding moves as integers
- copy/make approach for making moves
- negamax search with alpha beta pruning
- PV/killer/history move ordering
- iterative deepening
- PVS (Principle Variation Search)
- LMR (Late Move Reduction)
- NMP (Null Move Pruning)
- Transposition table (20MB fixed size)
- Material/PST (Positional Square Tables) evaluation
- Double/isolated/passed pawns evaluation
- Bishop & Queen mobility evaluation
- Very basic king safety
- UCI protocol

Congratulations

Pity that you lost one game against TSCP. If you had won 16-0, your Elo rating would be infinite

He did not loose a game. He drew one so he is still unbeaten. I guess TSCP played perfect chess and it was impossible to win

[maksimKorzh]

Congratulations

Well actually it was a draw.
I had TT of 98mb believe it or not...
I've reduced it to 20mb and started playing like this.
Also I've fixed timing bug - it dropped PV on less then 1500 ms due to to buffering.
I've added if (time > 1500) time -= 50 and that made a trick

[mvanthoor]

Ah, I see; a draw. I misread the results.

BBC is massively stronger than TSCP, and it has time management. It already has a lot of features... It will be an interesting opponent to play against in due time

It would be good to add a UCI-command to set the TT size. Most engines support this. In a tournament, engines get the same hash table size to equalize memory usage for playing. It would be unfair if one engine can store 32 MB of moves and the other has 64 MB.

With 20MB, you'd mostly be at a disadvantage in a tournament, and a list such as CCRL can't lower run a tournament with engines at 20 MB if they normally use 128 MB (for example), because it would skew the results. (The engines with established ratings, that would normally run with a hash of 128 MB would be weaker than normal, and so your engine would look like it's stronger than it really is.)

Sure, I'll add that. I just want to get some initial CCRL rating for this version first. Btw I can't see much difference between 20 and 98 mb I had before.

[Gabor Szots]

Very long time ago I did an experiment and found that every doubling of hash size was worth about 5 Elos.

[mclane]

Can you make it B strategy instead of AB ?
Why not ?
Would be interesting if it prunes away those branches that are not interesting.
I know it would weaken its ELO.

But on the other hand it would make more fun.

But on the other hand it would make more fun.

The major approach of the development is to use PST only as described here:
http://talkchess.com/forum3/viewtopic.p ... 15#p772515
This is both very exciting and something I'm incredibly interested in.

[mclane]

Yes I see but do you think it’s still state of the art to use this rudimentary thing ?

Why not try something different.
And create the strongest B strategy engine. Only relying on branches that are interesting or chosen ?
Why use brute force ?
Brute force is stupid, isn’t it ?
