This game is an excellent example of how you can fail to win a won position if you relax. I had such a nice position, but after I won the White Queen I stopped thinking, and suddenly my opponent started getting his Rook and Bishop into position.

Lichess rapid, 15+10
English Opening: Agincourt Defense
The learning from this game must be to stay extra focused after winning material, and shut down any counterplay instead of going into autopilot.
