Hello Udo,
latest Lc0 version (0.32.0) enables outputing the single best move for the current position, resulting from the neural network. This is a no tree search, equivalent to 1 ply evaluation. Similar to what Maia does.
Using the current top net (huge one, BT4-spsa-1740, 380Mb) you nevertheless get instant play without any requirement for a GPU.
Trust me, you won't get so many blunders as Maia does, rather furious games. A gambler chess player. And my guesstimate is around 2500 Elo!
Really worth a try.
To set Lc0 0.32 to play without any in-depth search, there is a trick: rename its exe file to some name including 'policyhead' string (such as lc0-policyhead.exe). The program has been designed in order to understand that.
MfG,
Eric
