Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.

Debugging is twice as hard as writing the code in the first
place. Therefore, if you write the code as cleverly as possible, you
are, by definition, not smart enough to debug it.

Can you analyze this opening position for me ?



The position is taken from an online game.
This is a position coming out of the QGA, where White has to labor to find any advantage -- even coming up with a playable line that offers at least equality is a challenge. White needs to get in moves like e4 and maybe d5 to get decent play.

The human attempt here would be to play 13.a3 so that white could carry out the freeing e4 push without worrying about an immediate b5-b4 by black. 13.a3 actually transposes to a Bogolyubow-Alekhine game, quickly drawn, from the WC match held in 1934. Alekhine equalized right away with 13...Nd5!, where e4 could be met by trading on c3 and then Be7, 0-0 and f5! with a good game for Black.

I consulted with Nezh on this one, and it suggests the immediate 13.e4!? as a more energetic approach. It was originally played by Laszlo Szabo vs Max Euwe. After 13..b4, Szabo went with 14.e5 and the Knights on c3 and f6 got traded off and White got no advantage, eventually losing.

Nezh suggests a possible improvement over 14.e5: 14.Qa4!?N a move that is bound to create more problems for Black, who now has to defend accurately. The e4 pawn will be given up for its c4 counterpart, and White untangles with a decent position, where Black is not objectively worse, but has to work out real solutions to the problems posed by White. The Queens get traded but White's pieces get active quickly. I would look into this, although it is more likely to help in OTB play than correspondence.

Kaissa thinks that e4 and d5 can transpose, but definitely no 0.00 eval for both. This is with Multi PV started after the single line search, so it can profit from that first search. The PV is now more similar to that of Louis's CFish. No tablebases though that can make a difference and there are some experiments going on in search. bench is a low
Total time (ms) : 2363
Nodes searched : 2785097
Nodes/second : 1178627
So somewhere shortcut but the bench was surprising. Small diff in evaluate.cpp compared to Stockfish 20190531.

Nice to read about the history of this line, and that it was played by Alekhine, Euwe, back in the 1930's I suppose. Cool, thanks for that!

Debugging is twice as hard as writing the code in the first
place. Therefore, if you write the code as cleverly as possible, you
are, by definition, not smart enough to debug it.
