4 piece puzzles

I encountered this puzzle in Puzzle Storm.
lichess.org/training/oqfNp
Does anyone else know of any other puzzles with only 4 pieces at the beginning of the puzzle?

Found another one.

@NNWill Slightly unrelated, but I've seen a lot of these at lishogi.org

can't remember off the top of my head if I've seen any of these. But i do love low-piece count puzzles!

@jdwhite42, those puzzles are tsumeshogi compositions. These puzzles are from actual games.

I have the database of puzzles downloaded on my computer. I found these:

lichess.org/training/1PQIH or lichess.org/training/2YAhd

Here’s a better question. Are there any puzzles with 3 pieces?

Classic 4 piece puzzle:

@NNWill I don't think there will be any point in 3-peice puzzles
