FEN: rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w KQkq - 0 1
Enter your move: d2 d4

note: If symbols are not showing use the following line of code
You should have nerd fonts installed in your system to see them

./start -u

Why?

• For fun
• I just learned C and wanted to build some project in it to learn more
• Also I like playing chess, here's my chess.com profile if you're interested

How?(for users)

First compile it using the command

make

note: You must have gcc compiler(you can use other compilers too but only if you know what you're doing)
Now to use it, run

./start [options] [side]

if you ommit the side it'll assume you're playing as white

side

• white
  simply, you play as white i.e bot will play as black
• black
  simply, you play as black i.e bot will play as white
• both
  you're playing from both sides i.e no bot moves
• random you'll do nothing but just see i.e bot will play from both side

available options

• -f <your_fen>
  You can use this option to set up your desired fen(or should I say position). However in place of <your_fen> you can also use
  • startfen for starting position
  • testfen for testFen[index]
  • ltestfen for testFen[last index]
• -u
  This option disables unicode symbols for representing pieces

example

./start -f "8/R1P5/4p3/1P2k3/8/2r5/5PK1/8 w - - 1 45" -u

   a   b   c   d   e   f   g   h
FEN: 8/R1P5/4p3/1P2k3/8/2r5/5PK1/8 w - - 1 45
Enter your move:

• -l
  Use this option if you want it to always show all the legal moves even if it's the bot's turn.
• -d <time_in_sec>
  Use this option to set delay between bot moves
• -h
  Use this option for any help

How?(for devs)

Just fork it and do whatever you want
note: If you're using my test script you need to have stockfish in your $PATH environment variable

Got a suggestion or issues?
