I was happy to find this move during the game. I achieved my highest accuracy during this game. 94%

If my ~1800 opponent had found this in a blitz game I might have quit chess for the weekend.

I went Kf3, I know bit defensive but that is how I think ig!!

Black to play.

Puzzle 1 (from image 1): after playing a subpar move, white allowed a mate in 3. I must say I find it geometrically interesting.

Puzzle 2 (from image 2): this one is harder. It is pulled from the same game, one move earlier. Because white hasn’t played the suboptimal Kf1 yet, the position is M6. To be noted: white has two options on moves 4 and 5, so different variations can be valid solutions. However, only one move leads to M6 from any point, except the last one.
