CCC: book test I (5|2) , 4 engines
in progress: 12 color-rev. openings each engine pair

                             Stockfish      Lc0        Dragon    Ethereal    (  totals  )              
1: Stockfish    44.0 / 72   XXXXXXXXXXX  +2 -1 =21   +3 -0 =21  +12 -0 =12   (+17 -1 =54)
2: Lc0          39.5 / 72   +1  -2 =21  XXXXXXXXXXX  +2 -0 =22   +6 -0 =18   ( +9 -2 =61)
3: Dragon       36.0 / 72   +0  -3 =21   +0 -2 =22  XXXXXXXXXXX  +5 -0 =19   ( +5 -5 =62)
4: Ethereal     24.5 / 72   +0 -12 =12   +0 -6 =18   +0 -5 =19  XXXXXXXXXXX  (+0 -23 =49)

144 of 600 games: white +28 -3 =113 59%  (draws 78%)


Almost 1/4 done, Stockfish has 3 more wins than the others combined, only 1 loss, to Lc0 but it has won vs. it twice.
Dragon has yet to win vs. the top 2, its 5 loses were vs. them.
Only Stockfish has won with both colors, twice against Ethereal (and vs. it only 2 both draws).

CCC: book test I (5|2) , 4 engines
in progress, each engine pair: 19 (of 50) color-rev. openings, 38 (of 100) games, played so far:

                             Stockfish      Lc0        Dragon     Ethereal   (  totals  )             
1: Stockfish   69.0 / 114   XXXXXXXXXXX  +3 -1 =34   +3 -0 =35   +19 -0 =19  (+25 -1 =88)
2: Lc0         63.5 / 114   +1  -3 =34  XXXXXXXXXXX  +4 -0 =34   +11 -0 =27  (+16 -3 =95)
3: Dragon      59.0 / 114   +0  -3 =35   +0 -4 =34  XXXXXXXXXXX  +11 -0 =27  (+11 -7 =96)
4: Ethereal    36.5 / 114   +0 -19 =19   +0 -11 =27  +0 -11 =19 XXXXXXXXXXXX (+0 -41 =73)

228 of 600 games: white +48 -4 =176 59%  (draws 78%)


Stockfish has 25 wins (2 less than Lc0+Dragon), its only 1 loss is 1/10th of the 10 losses for Lc0+Dragon!

Dragon is stil 0 wins vs. Stockfish and Lc0, with 7 losses to them.

Ethereal is still winless with 41 losses, almost half (19) to just Stockfish.

Since my last post:

Stockfish won another with both colors vs. Ethereal, Rounds 212 & 213, book C78 Ruy Lopez Moeller:
r1bqr1k1/1ppn1ppp/p1p5/2b1p3/2N1P3/3P1N2/PPP2PPP/R1BQ1RK1 w - - 5 10


Lc0 won two more vs. Dragon:
Rd. 192 After Dragon's 21...Nxb2?? {-0.84/26} diagram, then 22.Kxb2 b4 {-2.56} knowing it oopsed right away!
1rr3k1/2qbb1p1/p1npp1Pp/1p5R/4PP2/1NN3Q1/PnP2B2/2KR1B2 w - - 0 22

Rd. 204 Dragon, black, lost a pawn on move 25., its first worse than -2.00 (bad) was after 32...Rc1 {-2.15}

384 of 600 games: white +73 -17 =294 57%  (draws 77%)


Stockfish lost its 2nd game in 192 overall: to Lc0, but won another vs. it. Stockfish has more wins than draws vs. Ethereal.
Dragon is still zero wins vs. the top two, and lost another to each. (Update: after game 384 anoter Lc0 1-0 Dragon and a Dragon 1-0 Lc0.)
Ethereal is still winless, only at 30.5% performance.

Lc0 had a knight pair vs. black's bishop pair + pawn. However the engines at CCC agreed that white was winning, > 3.00 evaluations.
