EPD-Analyzer

Read epd file, analyze positions and save it to pgn and epd files.

A. Guide

1. Use python source code

• Install python 3.8 and above
• Install requirements.txt

2. Use eap.exe

• Download the eap.exe file in release link

B. Command line

• See sample batch file run_eap.bat
• Sample command line using default options
  python eap.py --input d:/chess/epd/wac.epd --engine D:/chess/engine/stockfish-11/sf11.exe --engine-option "Hash=128, Threads=2" --movetimems 1000
  or
  eap.exe --input d:/chess/epd/wac.epd --engine D:/chess/engine/stockfish-11/sf11.exe --engine-option "Hash=128, Threads=2" --movetimems 1000
• Use engine-name option
  eap.exe --input d:/chess/epd/wac.epd --engine-name "Stockfish 11" --engine D:/chess/engine/stockfish-11/sf11.exe --engine-option "Hash=128, Threads=2" --movetimems 1000
• Output pgn output to sfpgnoutput.pgn
  eap.exe --input d:/chess/epd/wac.epd --engine-name "Stockfish 11" --engine D:/chess/engine/stockfish-11/sf11.exe --engine-option "Hash=128, Threads=2" --movetimems 1000 --outputpgn sfpgnoutput.pgn
• Use a fixed depth to analyze the EPD.
  ... --depth 14 --movetimems 0
• Combine depth and time
  --depth 14 --movetimems 1000
  Engine will stop whichever is reached first.

  --movetimems MOVETIMEMS
                        input analysis time in ms, default=1000
  --depth DEPTH         input analysis depth, default=0
  --log                 a flag to enable logging
  --extend-search       a flag to extend the search if move in the pv is only 1, except if the score is already mate.
