Ditto from me!

Mike the position you posted (Smyslov Study on another post) is really interesting. Does the latest release get a mate score for this?

I've found with Houdini 6.0.1 default settings don't solve it but Tactical=1 does quickly.

Latest Komodo similarly default doesn't solve it but turning off Null moves solves it quickly.

Any similar results from McBrain?

Thanks Mike, I'll just add that by solving I didn't mean finding a mate score, although I tried!
