It was a last round, my opponent was a boy rated 1399. He played Scandinavian and then it became transposed Blackburne-Kloosterboer gambit. I found later that I played against it in 2010 and won, didn’t remember that. I think d3 made bishop on e2 passive. Then I made a bad move playing Nfd2. The idea was to force bishops exchange, but I didn’t see Nd4.

On move 10 he could play Bh3, though it looks above not only his pay grade, but probably mine too. He continued to press, but his 13… g5 was really bad being punished by 14. Nb5. After 14. Nxf5 I suddenly saw, that he has Bc5+ and Ng3#, so played Qe1. He couldn’t stop attacking, his Nh5 was a bad move. I realized that after queens exchange I will be better. Then I found 18. f4, 18… Nxf4 was better then 14… Nhg3+, which was -3. After bishops exchange he offered a draw, of course I refused.

It became technical, I made actually more moves than in the score-sheet. I played c4, d4, managed to win his “b” pawn and in a completely lost position having about 10 seconds left, he blundered a fork and resigned.
