Endgame training with Stockfish: depth, tablebases and practical drills

Endgame analysis is different from middlegame analysis. The positions are quieter, the evaluations are more stable, and small technique errors decide results. A little structured work goes a long way.

Start with the result, then the technique

Before turning on the engine, ask: is this position winning, drawn or lost with best play? Then try to prove it yourself. The engine will confirm or refute your plan. The gap between your answer and the engine's is the lesson.

Use tablebases for truth, engines for plans

Tablebases give exact results for positions with few pieces. They are invaluable for checking whether a pawn race is winning or whether a fortress is real. Stockfish is better for positions with more pieces and for explaining the plan.

For a practical repertoire, learn these endgame families:

• King and pawn vs king, including the opposition and key squares.
• Rook and pawn vs rook, especially the Lucena and Philidor positions.
• Bishop and knight mate, at least the technique.
• Same-colour and opposite-colour bishop endings.
• Queen vs pawn on the seventh rank.

Drill the key positions, not random ones

Set up the position and play it out against the engine or a bot. Repeat until you can convert without hints. Ten positions mastered is better than a hundred positions skimmed.

ChessUrge's game library can generate puzzles from your own endgame mistakes, which are often more relevant than generic studies.

Deep analysis has diminishing returns

Once the evaluation is stable, more depth rarely changes the practical lesson. Use a moderate depth for the plan and a tablebase for the exact result. Spend the saved time drilling the technique.

The best endgame training is the endgame you actually reach. Review your own games, find the recurring structure, and learn it properly.
