Playing Chess again in lichess.com + Puzzle

I have been on hiatus from chess for several months. I'm trying to play again and be good enough to join the Hive Chess Tournaments. I play 3 minute games in lichess.com with mixed results. As you can see my record is 8 wins vs 9 losses and my rating is below 1900.

Here is one game I lost on time wherein a common trap in the London System arose. White can win a piece after Black's blunder of b6. Can you find the winning moves?
