Made with my own pgn database and procedure :
1st "Hand tuning" bin component (~20.000 positions) : first 4 moves from chessdbcn eval + 2800 hard isolated positions variants +
Modified probalilities of first move : same probability for king, queen and english openings to have more open lines for white, and variety.
2nd bin : Grand Master winning games from chess.com (ELO>2700), restricted max 50 Plies. Black wins only bin + white wins only bin, then merge.
3rd bin : Games from Lichess Rapid-Classical time control only & min 2500 ELO. restricted max 50 plies. Black wins only bin + white wins only bin, draws only bin, then merge.
4th bin : Winning only engine games from JCER ,TCEC, CCRL, CEGT, FGRL, SPCC (only LTC, no blitz or bullet) restricted max 50 plies. Black wins only bin + white wins only bin, then merge.
