LeelaFish is a modified version of the Lc0 engine that gets help from an outside (auxiliary) engine. Leela uses the AuxEngine's PV to boost the Policy of those moves.

Which engine is this Eman? It's topping same rating lists in PlayChess! SF clone?

That is the theory that I subscribed to. I believe it is a Stockfish clone. Maybe someone else will correct me If I am wrong.

Why not let Leela play until there are X pieces left and then let Stockfish take over?
No need for an A/B veto early-middle game.

It seems that this Hybrid works only with GPU (CUDA). Right?

I have not tried it with CPU, but I would think that it should work with the CPU version. On second thought, I think you are right.
Only Cuda binary.

With default settings and SF10 auxiliary on 1 thread, +40 Elo points to pure Lc0 with t30 and t40 nets at bullet TC. Much better tactically. With late t30 nets, strongest engine on my PC.

Well ... it was only a matter of time that someone did the obvious. Kudos to whoever did that!

Pity aux engine threads are done in a clumsy way, instead of launching a separate instance of SF for each node on a different thread coz each instance of SF will use very little memory due to low hash requirements of SF search, it launches low-depth SMP SF search that is highly inefficient.
