The final checkmate patterns in the last puzzle (Gm Andersen vs. GM Pablo Salinas) isn't too hard. It is just two knights controlling a box like two bishops. Chess Tactics from Scratch, by Martin Weteschnik mentions them in the checkmate patterns. I had the Nxf2 as a candidate move, but didn't see that knight maneuver just after I had taken with the queen.
Sure! I'll check out that book since missing tactics is something I have to work on, so thank you for the resource.
I highly suggest you check out the entire game too, it was a nice collection of tactics, in the game the queen sac wasn't accepted and Salinas sacrificed it again later! Here I have the link so you can check it out https://lichess.org/study/v0vFRYfd
I think it's great that people share all kinds of puzzles here. In my opinion, these puzzles here are more valuable than any generic puzzles, because they were hand picked by members, with some thought put behind why they were posted. I like puzzles, and this is one of my favorite sections in the forum.
Here's a puzzle that's probably easy for most of you, but one I struggled a surprising amount with. It's not from my own game, although I'd like to post some from those as well in the future.
Deceivingly simple, didn't see it at first either. Great puzzle
