Lichess Tournament Position

Sep 3, 2015, 5:32 AM |
I had found this move sequence in a tournament game against a player who was 1750 and I was only 1535 (lichess ratings). I had 30 seconds on the clock and I had been winning for the past 6 moves. I felt he was still really dangerous if I played one wrong move but I knew it was a dangerous mating net.
Can you find it, and if so within 30 seconds?
