I am writing down few tips on winning games with QGD, also applicable to many other openings
1. start with d4 2. knights before bishop 3. castle early - kingside 4. rooks on open file 5. exchange central pawns 6. activate queen c2, b3, d2, e2 etc 7. bishop on b2, d3, g5 8. Exchange Bishop for knight when Knight is on the center capturing knight reduces opponent's threats win a pawn 9. exchange bishop for bishop if enemy bishop is on the center or having long diagonal 10. exchange rooks on open file but seize the open file 11. avoid rook coming to 7th or 8th rank or landing squares on 7th rank, c or f file 12. avoid knight forks in advance by moving pieces to be forked or defending the lending square 13. avoid f4 is white has no dark squared bishop to defend dark squares near king and black has queen and bishop to check 14. centralize own knight, defend by other knight so that they can replace the square when captured 15. knight outposts when opponent has no pawn or pieces to attack the knight or the pawn 16. escape squares for king with h3 or h4 17. defend every pawn and piece unless their sacrifice gives any winning advantage 18. look for all pawns or pieces that are undefended by the movement of its or others 19. exchanges or going to certain squares are not forcing moves. Only checks or threats of material loss are the forcing moves 20. build more than 2 moves threats in passive way so that opponent could not prevent it 21. attacking fianchettoed bishop by Bh6 is not always useful 22. flank attack with h or a pawn supported by rook, queen others can be threatening 23. having a passed pawn or connected passed pawns anywhere is winning 24. restrict opponent's passed pawn even by sacrificing pieces 25. restrict opponent's king movement and activate own king in the endgame 26. think for more than 3 moves in all rook endgame moves, how to capture pawns, restrict king, promote own pawn and create mating threats 27. in all other pieces or pawn endgames, passed pawn and restricting the king is the most important winning tactics 28. under time pressure, opponent can be deluded with mistaken but apparently right move 29. repeating moves in middle game and endgame is good but not in opening 30. in closed structure, exchange pawns and pieces as much as possible and get a passed pawn
