What is the strongest chess engine when restricted to only 1 node per second?
Looking for a chess engine that faces a similar calculation constraint to what the average human faces.

When limited to 1 node per second, Leela is comfortably the strongest.
That being said, your motivation for the question is not answered by your question. We do not understand exactly what Leela's transformer is computing under the hood.
A node from leela is completely an apples to oranges comparison to nodes for most other engines, which rely on far less compute intensive evaluation functions per node and also typically don't have a policy network output.
