Nimko (UCI) Chess Engine (v0.0.0 pre release)

[shahil4242]

I had created an UCI Chess Engine called "Nimko".This version is pre release.

[*]Board Representation and Move Generation is based on 0x88.
[*]Perft test is working well
[*]Move Scoring and Ordering is also completed based on PV -> Castle -> Capture -> Capture EP -> Killer -> History
[*]Evaluation is based on Material and piece square (from Glaurung)
[*]Searching based on iterative deepening,alpha beta,quiescence,Trigangular PVS
[*]UCI(is forked from Chenglite By Maksim Korzh) with only "go depth" command to search the moves

NOTE:This chess engine is made only educational and learning purpose.I donot want to steal other's people code and put it in my engine to make stronger and sell.

PS:I have been trying to make chess engine since 2016.But i failed miserably at perft test.But i am trying since 2016 and I succeed in (May,June)2021. Please help me in chess programming.

Thank you.Have a great day ahead.

Sample Game.

Sorry,due to some reason, i had made this repository private.

That's too bad. I would have liked to try it out, even in a pre-release state.
