Chess - Two back-to-back wins by Checkmate in 17 moves (9 and 8) DGT e-Board

These are the first two games I played today on chess.com. I won the first in 9 moves on a classic Fried Liver and the second in 8 moves when the opponent trapped their own king.
Chess.com rated my sacking of my knight (move #6) as a "brilliant" move.
