Re: mmt Vs. Ovyron (G4 D5 BG2)

I will analyze it for some hours. Stockfish thinks that some other options besides 5. Qxb7 are not awful so I'll guide LC0 towards checking them. Specifically, 5. cxd5 and 5. h3 with 6. Qxb7 can use a closer look.

Re: mmt Vs. Ovyron (G4 D5 BG2)

1. g4 d5 2. Bg2 Bxg4 3. c4 c6 4. Qb3 This is "Grob Opening: Grob Gambit, Fritz Gambit" or "Grob Gambit Accepted: Fritz Gambit" if anybody searches for it on Google. Wikipedia says "After 2.Bg2 Bxg4!?, White has an attack after 3.c4 and eventually Qb3, aiming at the weakened squares d5 and b7, an att...

Re: mmt Vs. Ovyron (G4 D5 BG2)

It'd feel quite surprising if 1.g4 does lose. If I lose, I'll go over key moves (e.g. when SF and LC0 disagree or scores are close or seem to trend in one direction with time...) with even more time and detail and then maybe we can also play out an alternate variation if the best move changes or if...

Re: mmt Vs. Ovyron (G4 D5 BG2)

at some point, say somewhere roughly between move 15 and 30, id prefere to rely more on SF rather than LC honestly...since this would require a very fast CPU though maybe even a cooperation might make sense at this point (if mmt doesnt use a fast one already) Yes, I actually specifically saw it whe...

Re: mmt Vs. Ovyron (G4 D5 BG2)

I am using mostly LC0 with some Stockfish 11 help. I'll be running difficult moves overnight and "easier" ones for maybe an hour or two. Good luck to you! I actually hope you win, so we can say that 1. g4 (or at least 1. g4 d5 2. Bg2) very much appears like a losing opening. That'd be something! 3. ...

Re: 1.g4 opening is losing?

1rq1r1k1/p3bpp1/2n2n1p/2Np3P/3P3R/BP1Q4/P2NPP2/R3K3 w Q - 5 24 LC0 gets itself in trouble here. It plays 24. Rd1 because it doesn't find the response 24... Ng4! in a reasonable time, while Stockfish 11 sees it instantly. Leads to a nice sacrifice 1rq1r1k1/p3bpp1/2n4p/2Np3P/3P2n1/BP1Q4/P2NPP2/3RK2R ...

Re: 1.g4 opening is losing?

I spent 3 weeks analyzing a single position of one of the variations of the 1.g4 d5 2.g5 mainline. How much is that, 504 hours? They weren't 24/7 but they were interactive so they may be equivalent to 1.5 weeks, but still... LC0 doesn't play 2. g5 though. I can have it look at this position. From a...

Re: 1.g4 opening is losing?

Black's advantage is much higher than that, I think some 1.60 would be unstoppable. According to? Not according to LC0 with a large net after 10+ hours of searching with 2080Ti and TitanV. That seems to be the longest search that's been posted so far. Based on that, it's doubtful that 1. g4 is losi...
