1 Dragon (3600)    82.5/140
2 Stockfish (3862)  81/138
3 Lc0 (3640)        79/139
4 Sf Classic (3781) 79/139
...

Interesting event.
I suppose it will come down to which engine gets the most 'upsets' like this one.

Opening after 7...Ng8
r1bqkbnr/pppppppp/8/8/8/8/PPPPPPPP/1NBQKBNR w Kkq - 3 8

Lc0 did not play very agressively, after 51...Rc6-c8
2rbb1nr/kp2q3/p3p2p/3pPppN/B1pP1P2/P1P1B1NP/1P3RP1/2Q3K1 w - - 42 52

A very strange opening: the Fool's Mate set-up but black has not moved yet!?
St'Classic sacrificed a pawn with 8.e4, a 2nd with 10.Nxf3, and the exchange on top of that with 17.Ne4. [Event "Odds Ladder (3|2)"]

One of the more (I think) unexpected results: Stockfish Classic 1-0 Rubi, Rd. 292.

White begins 2 pawns down: the book was in effect remove white's d2 and e2 pawns then white to move.
rnbqkbnr/pppppppp/8/8/8/8/PPP2PPP/RNBQKBNR w KQkq - 8 9


As expected Stockfish Classic's evaluations began in the -2.00 range.
Its first better than -1.00, though still 2 pawns down, was after 26.Qe3 -0.91
2kr3r/1p1q1p2/p1pp2p1/2n1pb1p/1PP5/2N1Q1PP/P4PBK/3R1R2 b - - 1 26


St'Classic's started saying 0.00 (Arena suppresses to no comment) at move 31. Then, still 2 pawns down, sacrificed  the exchange for pawn. It was soon winning:
