The story behind the game
Black exchanges a knight for a bishop and uses the resulting structure to activate the heavy pieces. A rook lift through e6 leads to pressure on the f-file, while the other rook enters d2. The later bishop check makes the coordination concrete and helps Black reach a favourable queen-and-bishop ending.

Ng4 challenges White’s central bishop. White develops the other knight to d2, and Black exchanges on e3. The f-pawn recapture changes White’s pawn structure and the open files. Compare those structural changes with the activity Black can obtain on the d- and f-files.
Re6 prepares another rook to join the pressure. White’s knight exchange changes the central pawns, while Black’s other rook can invade d2. The rook lift connects those plans. Judge the lift by its next useful destination and the targets on the second rank.
Rd2 enters White’s position with several possible targets. White contests the f-file, but Black’s other rook reaches f6 and exchanges there. The invading rook later captures on c2. Compare those two rook roles instead of treating the second-rank entry as an isolated pawn raid.
Bc5+ gains time before Black challenges the rook on d1. White’s king moves to h2, and Black plays Rd2. The rook trade leaves Black’s queen active on d2 with bishop support. Calculate the resulting queen-and-bishop position rather than assuming a rook exchange ends the attack.
Result: 0-1. The recorded score ends here; it does not imply checkmate.
