You're rated a little too high to not understand how tactics work... so I'm hoping it's not something dumb like you didn't notice the opponent was threatening mate in 1, one of your pieces was pinned, you assumed the opponent would reply with a capture, etc.

Speaking of "something dumb," some of the new problems have too many equal or better alternatives where the Stockfish finds one answer is best, but in real life, a different answer leads to a sure win with no unseen complications that the Stockfish answer requires.

For example, one I lost 11 points for had a solution were a N on each side was eliminated with a one-Pawn advantage where a Passed Pawn was a R-Pawn that is trickier than normal to win with.

My solution resulted in a 2 Pawn advantage with both N's still on the board, but the win was surer even if it might be longer.
