Book for SIMPLE endgame tactics?

Am looking for a book on simple endgame tactics. SIMPLE is the key here.

I say simple because I came across the "Simple Endgames" chapter in Polgar's 5000+ problem book. I've been studying endgames of late (Fundamental Chess Endings, etc.) so I felt I would blow all the problems away since they seemed to all be 2-3 movers, and was a bit horrified at how many dead-simple ones I either missed or had enough trouble with that in a super tight blitz endgame, i def would have screwed it up.

I would have guessed that my tactics problem ability (I'm around 1900 on lichess tactics) would have allowed me to easily solve all of them, but apparently endgame positions can be sufficiently different/tricky that it wasn't the case!

I've already done Asim Pereira's "Endgame Tactics" book, which I actually think is excellent and I'd highly recommend to anyone <1600, and especially if you're 1200 range.

I already have non-tactics type instructional books - Pandofini's Endgame Course, Fundamental Chess Endings, and my current favorite, Essential Endgames by Suveg, so I'm good with those.
