An early loss may come from a tactical oversight rather than a fundamentally unsuitable opening. Find the first decision you can improve.
What to do
Replay without the engine, identify when you stopped understanding the position and check the opponent’s forcing replies. Compare your move with a sound alternative and explain the resulting plan.
A mistake to avoid
Do not replace the entire repertoire after one loss. A new opening can reproduce the same calculation mistake in another position.
A detail worth checking
Separate memory failure from understanding failure. Forgetting a move and misunderstanding why a piece needed protection suggest different practice tasks, even if both produced an early loss.
Try this practical check
Save the critical position and write a short rule tied to it, such as checking a threatened piece before developing. Revisit the position before the next session.
