Here is my lichess range for each piece (not filtered by date) and the expect range ChatGPT generated as a general principle percentage range:
- Opening Phase (Moves: 61,087)
Pawns (40.6%): Typically, pawns should be moved to control the center and establish space. However, there is a risk of excessive pawn movement that can lead to weaknesses.
# Expected range: 35–40%. Anything higher can indicate too many pawn moves, reducing the speed of development.
Knights (25.1%): In the opening, knights should be developed early to control the center.
# Expected range: 20–30%. This is within normal range and represents good development.
Bishops (19.4%): Bishops should be developed early to help control the center and support the other pieces.
# Expected range: 15–20%. Too few moves might indicate passive or inefficient development of bishops.
Rooks (1.7%): Rooks usually don’t move in the opening phase unless for specific reasons (like castling or preparing to connect rooks).
# Expected range: 1–3%. This is standard since rooks are usually not involved early.
Queens (8.3%): Early queen moves can expose it to attacks and cause unnecessary tempo loss.
# Expected range: 5–10%. Moving the queen early can be risky, so this is within reasonable range.
King (4.8%): Castling early to ensure king safety is important.
# Expected range: 5–10%. This is within range, as the king should be castled early for safety.
- Middlegame Phase (Moves: 71,107)
Pawns (23.5%): Fewer pawn moves in the middlegame are expected since the pawn structure is generally set.
# Expected range: 20–25%. A bit higher could indicate too many pawn pushes, which may lead to over-extension or weaknesses.
Knights (20.4%): Knights are repositioned to better squares during the middlegame to control key points or support attacks.
# Expected range: 15–25%. This is within expected range.
Bishops (17%): Bishops typically become less mobile in the middlegame if their ideal squares are already occupied, but they may still be repositioned.
# Expected range: 15–20%. A bit lower may indicate underuse.
Rooks (14.5%): Rooks should be more active in the middlegame, especially on open or semi-open files.
# Expected range: 20–30%. This is the most notable deviation from expected norms. Rooks should start activating and moving to the center or open files. If they're not active enough, it suggests you're missing out on a key phase of the game.
Queens (15.2%): The queen should continue to be active in the middlegame, helping with attacks, defenses, and coordination.
# Expected range: 10–20%. This is within the typical range.
King (9.3%): The king typically stays more passive and behind the pawn structure in the middlegame, unless castling was already done.
# Expected range: 5–10%. This is normal.
- Endgame Phase (Moves: 67,806)
Pawns (22.6%): Pawns are more active in the endgame, often being pushed for promotion or to restrict the opponent's king.
# Expected range: 20–25%. This is normal, as pawns play a central role in the endgame.
Knights (8.9%): Knights are typically less effective in the endgame compared to rooks or queens due to the reduced number of pieces.
# Expected range: 5–10%. This is standard for the endgame, where knights are often less powerful.
Bishops (6.8%): Bishops are more restricted in the endgame, but they can still be effective in controlling long diagonals.
# Expected range: 5–10%. This is within range.
Rooks (24.9%): Rooks are extremely powerful in the endgame and should be active, often cutting off the enemy king or assisting in pawn promotion.
# Expected range: 20–30%. This is a bit higher than the middlegame, which is expected since rooks become more active as the game progresses.
Queens (9.7%): The queen is one of the most powerful pieces in the endgame and should be actively involved in both offense and defense. The fact that the queen is used less here could suggest more passivity in the endgame.
# Expected range: 15–20%. This is the second deviation from standard expectations. The queen should be more active, supporting pawns or creating threats. If it's not, it may indicate you're playing passively or failing to take full advantage of the queen's power.
King (27.1%): The king becomes more active in the endgame, often supporting pawn advances or controlling key squares.
# Expected range: 20–30%. This is normal for endgames, where the king's activity increases.
I assume every AI would give different range percentages according to their training or access to the internet where people have said things. I asked, on a new thread, the same question with the same values, and the answer was not a complete match in threads. I guess it's like, one chess coach telling you one thing and another chess coach seeing something else from the same values.
