     --------------------------------
     Stockfish lost only 2 games:
        1 game in 100 vs. Houdini
        1 game in 100 vs. Komodo

                                    Elo   +  -       Games      Score  AvOp  Draws
1 Stockfish_19082608c0  129.5/200 : 116  27 24  (+61 =137  -2)  64.8%   10   68.5%
2 Houdini-6.03std        90.0/200 :  22  25 26  (+18 =144 -38)  45.0%   57   72.0%
3 Komodo-13.1 (reg.)     80.5/200 :   0  26 27  (+12 =137 -51)  40.2%   68   68.5%


Komodo's first after-book move is 5...Be7? undoing 3...Bb4+, a full tempo down from normal variations.
Then its 9...Re8? allowed Stockfish's sacrifice 10.Bxh7+!, losing having only made 5 moves after the book!

With 15.dxe5 Stockfish sacrificed its Q for R+N+pawn.
With 21.Re1 Stockfish sacrificed a pawn, though after the game it found black's correct defense, in the viewer, Houdini's 21...bxa4?? soon was losing.
Houdini returned the exchange, 22...Rxf4, for black queen vs. 2 white rooks.
With 26.Rac1 Stockfish sacrificed its h-pawn although black had a dangerous looking pawn on a4.
Houdini said about equal the whole game until it was lost, 28...Qa3 {-0.03/28 5} 28. Red1 {+2.84/30 4} Qb2 {-0.03/25 6} 29. Rb1 {+4.17/30 4}, its B(f8) useless and king too weak. [Event "Sf_Ko_Ho"]
