Re: interesting position
Stockfish has a problem in this position, maybe pruning? Nxd6 wins also and even faster!

Re: interesting position
Taking the new Rebel bolide for a testrun, the behaviour was very different from Rebel 16 (first version of 16). Both had different winning moves, playing this move right from the start. Because of different moves they also show very different times to depth. Rebel 16 is still not at depth 32 and we are 15 minutes into the search. Rebel 16.1 would have passed that long ago even with a different move I think. I can not really compare that from this because of the different move choice. But I would not have expected this difference if the NNUE had not changed besides the change with pondering and the new time control algorithm. Mysteries 
Rebel 16 chooses Nxd6 but with less of a rise in eval I think to suggest it wins faster than Rf2. More than 18 minutes to reach depth 32.

Debugging is twice as hard as writing the code in the first
place. Therefore, if you write the code as cleverly as possible, you
are, by definition, not smart enough to debug it.

Re: interesting position
And always better together with some Forward- Backward of the near to each other moves and lines too as for trusting in their numeric evals at least compared to each other.
Good found, Jouni, here's SF dev. after some in and out of the two main lines and MultiPV=3 (hope you don't find it unfair here like you did in the other one thread, didn't you?
) About 5 minutes with 30 threads of 16x3.5GHz and 32G hash, after return from latest Backward (Forwward from Nxd6 first and Rf2 then secondly) started with full hash again then, here at depth 45:
