For decades, chess coaches have repeated the same mantra: "Study your rook endgames, they are the most common." But is this actually true for club-level players? When you have limited time to study, should you really be memorizing the Philidor position, or are you losing games because you don't know how to convert a pawn advantage in a pure pawn endgame?
To answer these questions, we analyzed over 847,000 Blitz games from the Lichess database, focusing specifically on the club-level rating bands (Chess.com 800 to 1500). We categorized every endgame reached, calculated conversion rates, and tracked how blunder rates change as the board empties.
This guide serves as a data-driven roadmap for your endgame study, showing you exactly what happens when the queens come off the board at your rating level.
The Reality of Club-Level Endgames
Before diving into specific endgame types, we must address a fundamental question: do club-level games even reach the endgame?
The data shows a clear progression. At the Chess.com 800-1000 level, about 26% of games reach move 40 (our proxy for the endgame phase). By the time you reach Chess.com 1300-1500, this number jumps to nearly 32%.
However, reaching the endgame does not mean playing it well. Our analysis of centipawn loss (CPL) reveals a startling truth: endgame accuracy is terrible at all club levels.
Even at the Chess.com 1500 level, the blunder rate (moves with a CPL drop of 300 or more) in the endgame remains above 40%. This is significantly higher than the blunder rate in the middlegame (33%) or the opening (9%). The conclusion is clear: the endgame is where club players are throwing away their hard-earned advantages.
The Most Common Endgames: Myth vs. Reality
So, what endgames are you actually playing? We classified every endgame position into families based on the remaining material.
1. The Rook Endgame Supremacy (It's True)
The coaches were right. Rook endgames (where both sides have at least one rook and pawns, but no other pieces) are indeed the most common endgame type across all rating bands. They account for roughly 14.5% to 16.2% of all classified endgames in the Chess.com 800-1500 range.
If we include endgames where one side has a rook and the other only has pawns, rook-involved endgames make up nearly 30% of all endgames you will play.
Actionable Advice for Rook Endgames: The data shows that club players struggle immensely with rook activity. In rook endgames, an active rook is often worth a pawn.
Chess.com ~1000: White plays Ra1? (passive) instead of Ra7! (active on the 7th rank). Rook activity is the #1 principle in rook endgames.
Instead of memorizing complex theoretical draws, focus on two practical rules:
- Always put your rook behind passed pawns (yours or your opponent's).
- If you must choose between defending a pawn passively or sacrificing it to activate your rook, usually choose activity.
2. The Pure Pawn Endgame Surprise
The most surprising finding in our data is the sheer frequency of pure pawn endgames (King and Pawns vs King and Pawns). They are the second most common endgame type, appearing in 11% to 15% of games, and their frequency actually increases as your rating improves.
Many players transition into pure pawn endgames thinking they are simplifying a won position, only to realize they have miscalculated the resulting pawn race.
Chess.com ~1100: White plays Kf4? (aimless) instead of Kd3! (supporting the d-pawn and preparing to create a passed pawn). In pawn endgames, the king is a fighting piece.
Actionable Advice for Pawn Endgames: Pawn endgames are pure calculation. There are no pieces to bail you out of a bad plan.
- Learn the rule of the square to quickly determine if a king can catch a passed pawn.
- Understand opposition and outflanking.
- Before trading the last pieces to enter a pawn endgame, you must calculate it to the end. If you aren't 100% sure it's winning, keep the pieces on the board.
3. The Opposite-Colored Bishop Draw Margin
We specifically looked at Bishop vs Bishop endgames. While our dataset groups all B vs B endgames together, the draw rates are staggering.
At the Chess.com 800-1000 level, bishop endgames end in a draw 46% of the time. Even at the 1300-1500 level, the draw rate remains around 32-39%. This is vastly higher than the draw rate for knight endgames (27-43%) or rook endgames (27-35%).
Chess.com ~1200: White plays Bc3? (passive retreat) instead of Bc5! (restricting Black's king and controlling the a7-g1 diagonal). In bishop endgames, diagonal control is everything.
Actionable Advice for Bishop Endgames:
- If you are losing, actively seek to trade into an opposite-colored bishop endgame. It is your best drawing resource.
- If you are winning, avoid opposite-colored bishops unless you have a massive material advantage or widely separated passed pawns.
- Put your pawns on the opposite color of your bishop so your bishop has open diagonals and your pawns control the squares your bishop cannot.
4. The Queen Endgame Chaos
Queen endgames (Q vs Q with pawns) are relatively rare, occurring in only about 0.5% to 1% of games. However, they are characterized by high draw rates (20-29%) due to perpetual check.
Queen endgames at club level: Black has a Queen vs Pawns. At Chess.com 800-1500, players fail to find perpetual check resources ~75% of the time, leading to unnecessary losses.
Actionable Advice for Queen Endgames:
- King safety is more important than material. A naked king will be subjected to perpetual check, regardless of how many pawns you are up.
- Centralize your queen. A centralized queen controls the most squares and is the best piece for both attacking and defending.
The Conversion Problem
Perhaps the most sobering statistic for club players is the material conversion rate. How often does a material advantage actually translate into a win?
At the Chess.com 800-1000 level, being up a full pawn (+1 to +2 points of material) only results in a win 54% of the time. Even being up a full minor piece (+3 to +4) only converts 60% of the time.
Most shockingly, when players are up a full Rook (+5 to +6), they still fail to win roughly 30% of the time at the 1000 level, and 25% of the time at the 1500 level.
Actionable Advice for Conversion:
- Stop relaxing. A material advantage is not a win; it is merely the potential for a win. The data proves that your opponents will fight back, and you will blunder.
- Simplify safely. When ahead in material, trade pieces, not pawns. But refer back to our rule on pawn endgames: only trade into a pure pawn endgame if you have calculated it to a forced win.
Your Endgame Study Roadmap
Based on the data, here is how you should allocate your limited endgame study time if you are rated between 800 and 1500 on Chess.com:
| Priority | Endgame Type | What to Study | Why it Matters |
|---|---|---|---|
| 1 | Pure Pawn Endgames | Rule of the square, opposition, creating passed pawns. | 11-15% of games. They are foundational; every other endgame can simplify into them. |
| 2 | Rook Endgames | Rook activity, cutting off the king, Philidor/Lucena (basic concepts, not deep theory). | ~15% of games. The most common piece endgame, and highly tactical. |
| 3 | Material Conversion | Safe simplification, avoiding stalemate, king safety. | You are currently failing to win 30-40% of games where you have a significant advantage. |
| 4 | Bishop Endgames | Opposite-colored drawing tendencies, pawn placement. | High draw rates make them critical for saving lost games and converting won ones. |
The endgame is not a boring phase where games slowly fizzle out. At the club level, it is a chaotic battlefield where advantages are squandered and lost games are saved. By focusing your study on the endgames that actually occur—Rook and Pawn endgames—you will stop throwing away your hard-earned middlegame advantages.

Data and Methodology
This analysis was conducted using a dataset of ~847,000 Lichess Blitz games, accessed via the grandmaster-guide MCP server. Ratings were adjusted to approximate Chess.com equivalents (e.g., Lichess 1200-1400 ≈ Chess.com 800-1100). Endgames were classified based on piece inventory at the start of the endgame phase.
