This is a round 11 game between AI Leela Chess Zero v20.2-32930 and Stockfish 190203. It was from the Season 14 Superfinal of the Top Chess Engine Championship 2019. Both Leela Chess Zero and Stockfish earned their way to this final 100 game match. The featured game demonstrates how exactly Leela earns that first full point. The opening played, French Defense: Tarrasch, Guimard variation with its early fixed pawn center, is in my opinion ideal for the neural network.

This game reminds me of when Kasparov led Deep Blue to a very closed position and completely dominated with his ability to play strategically to win the match and the tournament. At the time, it was telling of how computers were limited creatively in closed positions and Kasparov took advantage of that. Except in this game, AI Leela plays in the role of Kasparov and teaches the same lesson to Stockfish!

The strategies, nuances, and subtle imbalances of Chess seem like a lifelong educational journey; a private journey which luckily he's willing to embark upon publicly. With all due respect to the top players, in my opinion, few people--if any--have done more for the game of Chess in the last few years than Agadmator and ChessNetwork.

@TheVirindi 5 жыл бұрын

Expending all that structural effort to get the knight on b3 seems like a pretty typical heuristic-based mistake. If your evaluation heuristic says that a support knight forward in the enemy camp that cannot be attacked is good, then the engine will prefer this sort of position even though in this case it makes no sense and essentially kills the piece. That useless knight seems very "computer-like" to me, and the way Leela ignores it seems like what you might expect from a human player. Stockfish was just painting by numbers with that piece :)

@DraoxxMusic 5 жыл бұрын

Leela actually didn't 100% ignore it. The knight would've been a monster if it was allowed to go from d2 to e4, so Leela always made sure that a piece guards d2. A rook was always guarding d2, so it wasn't really a bad trade for Stockfish -- an inactive knight vs an inactive rook.

@TheVirindi 5 жыл бұрын

@@DraoxxMusic Another decent threat was c1->d3. Leela guarded against this later in the game with her knight on f4, which allowed the rook to leave the first rank. The number of squares available for that knight to escape was few enough that it was always possible to guard them while also making use of the guarding piece for other purposes. So, the guard pieces were doing something while the black knight was doing nothing but sitting there. Note that on g2 the rook was doing quite a lot while still guarding d2.

A quick question if I may: At 19:35 you said that there would be no way for the white Queen to place a check on the King after he has moved to a6 (move 39). But she could have used the 6th file for a horizontal check on d6, no? D6 being unprotected, I find it almost nicer of a spot, looking at the black d/e pawns. This doesn't really matter for the game as a whole, since it developed otherwise, but I was just wondering if there is a problem with that strategy.

A second attacker on white's d-pawn (well defended, but still) and preps a move like ...b4 (which is now supported by bishop and knight) to break the queenside and get a deep passer. Obvious glaring issue is king safety, but the on-board game felt too passive!

One thought occurs to me ... the biggest thing here may not be the strength of this program but how quickly it became so strong, and the fact that the ‘algorithm’ used is flexible and adaptable to different domains. I suspect the techniques used to make Stockfish et. al. strong in the chess domain are not transferable to other domains whereas those used for Leela are. For analyzing such systems mot only should we compare their raw strengh but also some metric as to the ‘energy’ required for them to get to that strength, the time to do so, and their level of flexibility vis-a- vis other domains.

I initially thought that black knight on B3 was black's best piece, until you pointed out how it could actually be the worse. Seems like something stockfish did because it knows that a knight on a forward outpost is generally good, and didn't really consider the fact that action was taking place on the king side, and that no coordinated attacks could happen due to the locked down position. It seemed like stockfish wasted a lot of moves, especially compared to white. You could tell that the engine didn't have a plan of attack. It had plenty of time to set up an attack on the queen side, hoping to promote one of it's many advanced pawns.

Right, Leela runs on the pair of 2080 graphics cards. This neural network that runs on the GPU is an entirely new class of engine completely unlike the brute force CPU-intensive Stockfish (and basically every strong engine that preceded Stockfish). Leela looks at orders of magnitude fewer variations when it ponders and still ends up with amazing games like this.

@@lmabacus404 It's very easy to say that Stockfish should've developed its pieces, but it was very hard to see where the positions of the bishops and rooks could've been improved in the early mid-game. Stockfish's "mistake" was strategic, not tactical. It chose to position the knight down the board thinking that it could provide play, but Leela just moved everything to the other side of the board making it irrelevant. It turns out that the knight was necessary to shut down advance king side, but it was always three moves away from being able to help out and thus too slow. There were no tactical mistakes, Stockfish was just outplayed strategically.

Jerry: I have a favor to ask: Could you get the TCEC guys to give precise power usage numbers on the current TCEC server vs the GPU server? Not estimates, but: Connect a watt measuring device to the thing (e.g. the Kill-A-Watt device), and report how many watts are being used during peak load. In fact what would be really amazing would be a graph of power-draw vs time. I can't seem to get a straight answer by searching online (or asking elsewhere), and I think this is the most fair comparison for what is basically an apples to oranges comparison of different kinds of commodity hardware.

@quag443 5 жыл бұрын

Power usage is a good metric but for it to be fair, both hardware needs to be around the same age. TCEC's CPU was made with technology from 3 years ago while Leela's GPUs are barely half a year old, so assuming newer tech is more efficient, the comparison may lean slightly towards Leela. There's been discussion for TCEC to sell the old server and rent a newer one but I'm not sure what came of it.
