It is a very playable move by a patzer like me, much in the fashion of an inverted Fegatello Attack. I know that your surprise comes from that Stockfish 14.1 16T is not a patzer at all.

Anyway, thank you very much for pointing to such an avoid move that looks really sensible. Analysing with SF 18, the position after 4.- ..., Ng4 leaves a position where only 5.- d4 is good for white (~ +0.75), while the next best move is 5.- Bc4 with bad evals (~ -1). After 5.- Bc4 is played, SF 18 slightly prefers 5.- ..., Bxf2+ over 5.- ..., Nxf2 at low depths, then leans more clearly to 5.- ..., Bxf2+ and even 5.- ..., d5 (~ -0.2) is preferred over 5.- ..., Nxf2 (~ 0).

When 5.- ..., Nxf2 is played, 6.- Bxf7+ is the only move for white with 0 evals and when played, black loses with 6.- ..., Ke7 but draws with both 6.- ..., Kxf7 and 6.- ..., Kf8.

9.- ..., c6 is the definitive error by black in this wonderful miniature, but my feeling is that SF 18 does not understand very well the position because the d4+Nd5 idea changes SF mind from drawn (or even unpleasant at low to mid depths) into a better for position for white (~ +0.5) after playing the moves, not before. SF definitively needs more time to think: starting after 7.- ..., Nxh1 with hash cleared, a positive eval for 8.- d4 first came at depth 24 in my run and negative evals circa -0.5 remained until depth 18. It is very uncommon in SF. After circa +0.5 evals, 0 evals came at depth 27 again:

Re: Stockfish 18 progress vs Lc0

Post by jorose »

This is a very well known opening (Traxler variation of the Two Knights defence, aka Wilkes-Barre) with reverse colors, though the extra tempo (a3) is of unclear value to me. It is considered somewhat dubious, primarily due to the Bxf7+/Bxf2+ lines, less so due to the Nxf7/Nxf2 lines. As Leela shows in the game it can have quite a lot of venom if you don't defend carefully against it.

Very nice test MMarco!

Interesting game indeed. Thank you for pointing it out. When I run SF 18 on a single thread, it switches between 5...Bxf2 and 5...Nxf2 and prefering the latter one as far as depth 33. I assume that is because the tactics are complicated.

What I find really curious is that SF still gives a winning eval for black on move 9 (at depth=20, preferring 9...c6 over 9...d3) and 10 (at depth=23). Single threaded SF avoids that at lower depth.
