It's a draw...

Is there an engine that rates this position as a draw?
Maybe one of the ancient AB programs without null move pruning?

I do not see the relevance of null move pruning.
It is not a draw that you can see by search unless you search 100 plies forward.

Of course, humans and computers play different chess. Nevertheless, it would be wonderful if we had engines that could immediately evaluate such a position correctly as a draw. Just like any beginner can do...

You need engine with fortress detection:

Good hint
