1st StockfishClassic, 2nd Komodo 14.1; so they got to play a sufi.

TCEC S20 - Sufi Bonus 1 - G/12'+3"

StockfishClassic  Wins w/b  Losses     Draws       Elo +-
65.5/100  65.5%   38 [30/8]  7 [1/6]   55 [19/36]  112 46
34.5/100  34.5%    7 [6/1]  38 [8/30]  55 [36/19]    0 44
Komodo 14.1

Wins excluding 5 (!) same-color-won 1-1 pairs:
Sf-Classic 32-2 Komodo 14.1 (16:1 ratio)
The only Komodo wins that StockfishClassic did not win the reversed:
8.1  Robatsch (modern)  B06
51.1 King's Indian      E73
But Sf-Classic had 32! and wins in similar openings also.


StockfishClassic invents a dangerous gambit, 9.h5:

In the colors reversed Komodo played 13.e4 instead of the human 13.h3, then Sf-Classical took advantage of that with 13...Ng4 and 14...Nge5:

Hi MrKris, For what it is worth in my database I have 17 games with 9. h5 as played in the first game, the TN for me was 13.Nh4 .... I found 1 game with 13. e4 being played as in game 2

Regards
Tony

Thanks!

My theme with ChessTempo.com (FIDE & some correspondence) is humans vs. engines.
Maybe humans have underestimated 9.h5, first game.
But I think they have an interesting idea with 13.h3, second game (and Stockfish PV=6 at the bottom of the bottom).

Interestingly, from your .pgn, 9.h5 has been played by the top engines but also several by Winter and one each by Ethereal and Booot.
At the bottom is from PC vs Scid from your 17 games, nice white percentage.

In your attached Gull failed to play 13...Ng4! as in Komodo14.1 1/2-1/2 StockfishClassical TCEC.
