And SF doesn't know bishop+knight checkmate.
Stockfish is Dumb

It's not just Stockfish. You'd probably be hard pressed to find any engine that realizes it's a draw.
Yet a 1400 player can see in 3 seconds it is a draw. What if earlier SF had a choice of trades and could have had a bishop or knight and chose the bishop because it is an open position and the bishop is worth a few centipawns more?

In full disclosure, I did not come up with this on my own. Simon “Ginger GM“ has an interesting video on Chess engine quirks. For the heck of it I decided to set up the position and see what the computer thought of the position for myself, and voilà he was right.
But truth be told, if I managed to force Stockfish into such a position I would feel like a God.

If it was dumb then this wouldn't be news.

Engines simply aren't too good at calculating fortresses. For a human, however, it's easy to see no breakthrough for white; even trying w/ his bishop doesn't work as black can simply repeat w/ Kc7 and Kd6 to score a draw.

Put one bishop on g2 and get the other to g7, then take on e5 when the king steps back. Two same color bishops is a win for White.
Two (or generally more) same coloured bishops is usually NOT a win without co-operation.
Eg try 3k4/8/2B5/3B4/4B3/8/8/4K3 w - - 0 1 in a tablebase.
(I am unsure why people have copied the starting board from a draft of my post: this was only there because of what seems like a remaining bug in the diagram editor).
