a1=N# Is that it?

I’m good at solving puzzles. Now spotting them in a game…

By far the best resource for endgames is Silmans Endgame Course (book or chessable). Also Chessmood sells an endgame course too

Ng1+ Kg4 Rf4+ Kh5 Rh4#

Dang!

I think it's 1.Bxg7 Kxg7 2.Rxf6! and Black has to play Kxf6 Qf4+ (otherwise exf Qh7#) and White nets the e5 knight

Qxf6 was the most forcing line

Yup... nearly 300 point difference. Course I'm not really 100% focused on blitz, so my fault I guess

Whatever it is, regular tactics + play seems to be essential. How much, how often, how difficult... not sure

I started out d4, switched to e4 gambits based on my coaches recommendation, and have since switched back to d4. Those e4 lines are forcing - but punishing if you forget one move or waste a single tempo
