Amazing attack by Stockfish 16 in the London System as black.
Stockfish continues to demonstrate its ability to discover superior moves with remarkable speed. In self-play against Stockfish 15, this new release gains up to 50 Elo and wins up to 12 times more game pairs than it loses. In major chess engine tournaments, Stockfish reliably tops the rankings winning the TCEC season 24 Superfinal, Swiss, Fischer Random, and Double Random Chess tournaments and the CCC 19 Bullet, 20 Blitz, and 20 Rapid competitions. Leela Chess Zero was the challenger in most finals, putting top-engine chess now firmly in the hands of teams embracing free and open-source software.This updated version of Stockfish introduces several enhancements, including an upgraded neural net architecture (SFNNv6), improved implementation, and refined parameterization. The ongoing utilization of Leela’s data combined with a novel inference approach exploiting sparsity, and network compression ensure a speedy evaluation and modest binary sizes while allowing for more weights and higher accuracy. The search has undergone more optimization, leading to improved performance, particularly in longer analyses. Additionally, the Fishtest framework has been improved and is now able to run the tests needed to validate new ideas with 10000s of CPU cores.Stockfish now comes with documentation, found in the wiki folder when downloading it or on GitHub. Additionally, Stockfish now includes a clear and consistent forced tablebase win score, displaying a value of 200 minus the number of plies required to reach a tablebase win. Furthermore, the UCI_Elo option, to reduce its strength, has been calibrated. It is worth noting that the evaluation system remains consistent with Stockfish 15.1, maintaining the choice that 100cp means a 50% chance of winning the game against an equal opponent. Finally, binaries of our latest development version are now provided continuously as pre-releases on GitHub making it easier for enthusiasts to download the latest and strongest version of the program, we thank Roman Korba for having provided a similar service for a long time.

What a great queen sacrifice If i could remeber all of this it might make thism poisoned pawn line playable again. Thanks Josip.

All the pawns are poisoned. It's a poison army.

@thalesbernardomendes8949 Ай бұрын

Its not really a sacrifice, since you take a rook, a bishop and a pawn for the queen

@joseraulcapablanca8564 Ай бұрын

@@thalesbernardomendes8949 I thought the same, but since it takes a little time to collect, I thought we can get away with calling it a sac.

C3 is the correct 3rd move for White if you want to stay in the London. Then when Black's Queen comes to B6, White's Queen goes to B3

Truly amazing Queen sac vs London right out of the opening worthy of study not only to use if given opportunity against the London, but as an example of when & how a Queen sac gives good compensation.

@jlsabinas8578 11 ай бұрын

Wow, that b2 pawn is pretty much poisoned from the start! It's crazy how from move 4, Black could suggest White resign, lol.

@doncherf2610 10 ай бұрын

Not much of a sacrifice when it costs the victim 2 pieces and a pawn. It's an even exchange.

hey jozarov i know you and agad may not discuss chess variations over family gathering all over but you must show him this line this is the line that he showed on his channel on how to play against the London but he just said for the purpose of not getting our queen traped you just play a6 show him this one he will be thrilled

Not only, but when an engine wins a game against Stockfish its a prearranged game in which Stockfish has to Play a bad opening

White is still better here but needs to be precise.

@kugelblitzingularity304 11 ай бұрын

Ah this is one of the interesting lines black can try against the London. After Qxb2 white is slightly better in a few lines. But these lines actually have Stockfish mis evaluating a bunch on low depth, but thats a year or two ago. So practically unplayable opening for humans lol.

@alejandrocorrales5472 11 ай бұрын

The SF engine opponent didnt develop or create an escape square for his king, nor did he castle short, whereas SF had wonderful counterplay by outplaying the other engine with superior tactic and rapid development
