EloCoach’s review · unedited
You spent fifty moves defending an objectively lost rook endgame before squeezing blood from a stone. The decisive turn came on move 58, when White walked into Rf3+, surrendering the a-pawn and letting your king shoulder theirs away from the kingside.
The Opening: Alekhine Defense, Sämisch Attack
You chose the Alekhine Defense: Sämisch Attack, meeting 1.e4 with 1...Nf6 and responding to 3.Nc3 with 3...Nxc3 4.dxc3. The line trades Black's active knight to double White's c-pawns, but concedes easy piece development and open files to White.
The Early Structural Concession
After White pinned the knight with 6.Bb5, you put the question with 6...a6. White cashed in the bishop pair immediately with 7.Bxc6+, and on move 7 you played bxc6, recapturing toward the centre and accepting a compromised queenside structure. With the pawn on a6 undefended and c7 backward, your pawn structure became brittle early.
Trouble brewed when you opted for 8...f6 to challenge White's e5 outpost. White exchanged pawns on f6, leaving your e-file open and your king uncastled. On move 10 White posted Nd4, eyeing the weakened light squares. When White delivered 11.Qh5+, you answered with 11...g6, blocking the check and attacking the queen via interference, while creating dark-square holes around your king.
The Middlegame: A Pawn Down Under Fire
The position turned precarious when you stepped out of the pin with 12...Kf7 instead of developing the dark-squared bishop to g7. White quickly snatched the c6-pawn with 13.Nxc6.
Walking the Tactical Tightrope
White attempted to complicate with the discovered attack 14.Nd8+, and you responded with 14...Rxd8, trading rook for knight because the queen on b7 hung behind the tactic.
After White grabbed the b7-bishop, you counterattacked with 15...Qb5, forcing White to take on c7 with check. On move 16 you defended with 16...Rd7, shielding your king and attacking the enemy queen along the d-file. White struck back with 17.c4, provoking a sequence of exchanges that liquidated into a pure rook endgame where White maintained an extra passed pawn.
On move 27 White traded minor pieces with 27.Bxe5+, and you recaptured with 27...dxe5, keeping your king anchored and maintaining a central pawn barrier against White's rooks.
The Squeeze: Surviving White's Passed Pawn
White established a protected passed pawn on c7 by move 37. With White's rooks doubled behind it and cutting off your king, your defense had to be airtight.
Under heavy pressure, you found 37...Rb7, blockading the pawn's promotion square from the flank. While the computer points out radical counterplay with pushing your e-pawn, your move was the practical human choice: it directly controlled the queening square and prevented White from advancing without conceding the pawn.
On move 47 White checked with 47.R5c4+, and you chose 47...Kf5. Moving your king toward the kingside allowed White to keep pressing with their king. Centralizing with the king on d5 was more resilient, cutting off White's king infiltration entirely while using the d-file as cover.
White pressed their king to d5, but on move 53 miscalculated by allowing 53...Ra5+ followed by trades on c7 and c3. By move 55, all the queenside pawns were gone, and the game reduced to an equal four-versus-three rook endgame.
The Turning Point: White's King Steps Into the Fire
The game stood balanced until White cracked on move 58.
White played 58.Kf4, walking into the line of fire. You punished it on the spot with 58...Rf3+, exploiting the alignment between White's king and the undefended a3-pawn. When White retreated with 59.Ke4, you played 59...Rxa3, picking off the last queenside pawn with check tempo and leaving your passed g- and h-pawns free to run.
The Conversion: The Kingside March
Once you secured the material balance, your execution was clinical. On move 61 you marched your king to g5, cutting off White's king via an active outflanking maneuver.
You pushed White's rook backward with 63...Kh3 and 64...h4. When White attempted to contest the eighth rank, you pushed 66...g3. After the pawn trade on g3, your g-pawn was unstoppable. On move 68 you pushed g2, forcing White's resignation as the pawn promotes next move.
Strengths
- Resourceful endgame defense. When White pushed the passed pawn to c7 on move 37, you stayed calm, blockaded the pawn with your rooks, and waited for White to overextend.
- Conversion precision. From move 58 onward, once White blundered the a-pawn, you did not play a single sub-optimal move. You used your rook to cut off the enemy king and escorted your connected passed pawns directly to promotion.
Areas to work on
- King centralization in rook endgames. On move 47, when checked on c4, you moved your king away from the action with 47...Kf5 instead of centralizing with 47...Kd5. In rook endings, bring your king toward the passed pawns; stepping backward or sideways concedes crucial squares to the opposing monarch.
- Opening king safety. The pawn break 8...f6 weakened your e-pawn and opened central lines before you had castled, forcing your king to manually wander to f7 on move 12.
Coach's Verdict
This was an exercise in high-tier grit. You were on the back foot from move 8 through move 50, surviving a minus-four position against a 2640 opponent through stubborn defensive technique. The moment White blinked on move 58, you terminated the game in ten moves. To push your game even further, avoid creating self-inflicted structural holes like 8...f6 that force you into fifty moves of defensive triage in the first place.
The coach asks
On move 47, when White gave check on c4, what made you prefer stepping to f5 rather than occupying d5 with your king?
- I wanted to keep my king near the f- and g-pawns
- I was worried about mating nets along the d-file
