I just had a win against someone who was 100 rating points higher than me. Here it is!
15.Qd8#
Well played - missed 15. Qd8# but other than that you got your opponent on the ropes very well
17. Bd6+ black can play QxBd6 and you lost a bishop
Not perfectly played, but still a good win. Congrats!
Nice going.
20 c3 looks a bit quicker
20 h3+ Kh4 21 Kh2 g5 22 g4 forces mate in a few
22 h3 also ends it quickly, and 22 Qh6+ is mate in 3 (22... Kxg4 23 h3+)
Also 24 Bf6 forces 24... g5, after which you have 25 h4 (25... gh 26 Qf4+ mates next)
