In the TCEC 19 superfinal I finally tried the main line Frankenstein-Dracula, i.e. 8... Qe7 (previously I mainly used 8... Qf6!?, thinking that is the better move). The result: both Leela and SF drew easily with black. Also note the games were identical for 25 moves (!!), which is the result of both engines having a similar evaluation now.

Thanks for the info.!

ChessTempo.com (free) has:
'all games' 8...Qe7 136 games, 8...Qf6 35 games, 2 others;
'both 2500+' 8...Qe7 only 2 games (draw & bk. win), no others.

Excuse me for complaining:

http://www.fastgm.de/16-60-0.6.html
1   Stockfish 12   3509
14   Stockfish NNUE GK200627   3445
'GK' answered my question on Discord - he used his own, one, recent Intel 6-core (12 thread) CPU to make his net.
Versus how many googaflips to make each Lc0 net?
[Pre-internet math terms: googol=10 to the 100th power, googolplex=googol to the 100th power.
Google misspelled it so Google search could find itself easier.]


It is almost as if Lc0 is causing global warming to make a weaker Stockfish fork for GPU card(s) costing more than a computer's CPU.
However, the J92's are doing well, but some of them seem to regress and the 190 lost to the NNUE-era Stockfish in SuFi 19 more than Lc0 lost to Stockfish-classical in SuFi 18:
3   Lc0 0.26.3 RC2 384x30-J92-130   3505
(the LS nets are good but may have an advantage at lightning from being smaller)

P.S. Thanks for the Halloween and Elephant Gambits in SuFi 19!
