Two Knights cannot mate
Position: 7k/8/5K2/4N1N1/8/8/8/8
Two knights and a king cannot force mate a lone king. Keep your king off the corner squares and the position is a dead draw.
Why this position matters

PawnPilot lets you play this exact position against tablebase-perfect defence: every slip is caught, explained, and re-scheduled for review until the technique is automatic.
