Black to move


First move I look at is 1...Nf5.
That was my choice too. It's second best, though winning.

Re: Nice Position for Humans

Well, I chose a winning move, but apparently not the "best" move.

Re: 1.g4 opening is losing?

Newest T60 Leela network gives eval of -73% for after 1 Million node search (a bit over a minute on 2080ti). If 1.g4 is losing it's interesting to ponder if openings like Benoni or Mar del Plata King's Indian variation are losing as well. If you play around a bit you get around 65% for white in tho...

Re: Dylan Sharp Vs. Harvey Williamson (G4)

The sub-tree that has to be stored in the TT is way to large for a normal sized TT. So, if it is a draw, you will need a very large TT in order to find it and be somewhat sure that your analysis is accurate. Back when SF could have 1 TB of TT I think it was possible. But IIRC this has been reduced ...

Re: 1.g4 opening is losing?

Realistically white isn't going to win any game, so do we get better %s if we take out possible white wins from the computation? Well, the conditional probability that White draws with 2. g5 given that White doesn't win seems to be 0.326 / (0.326 + 0.564) = 0.366. You're welcome to make analogous c...

Re: Dylan Sharp Vs. Harvey Williamson (G4)

After a day-long search with MultiPV=2, Stockfish suggests that 16. Re1 is sub-optimal, and that White is already in considerable distress: -1.82 16. Rfc1 Rfe8 17. Qd3 Bxf3 18. Qxf3 Nh4 19. Qh5 Nxg2 20. Kxg2 Qe6 21. Qf3 Qxe2 22. Qxe2 Rxe2 23. Rd1 Rd7 24. Kf1 Re6 25. Re1 Rxe1+ 26. Kxe1 f6 27. gxf6 g...

Re: Dylan Sharp Vs. Harvey Williamson (G4)

What I think is the most likely case is that either 1.g4?? loses by force, or 2.g5?? loses by force, because the rest just went downhill faster... but since I lost a position I guaranteed that I could draw what I think about it might not matter :mrgreen: Here is a Stockfish-PV that I saved from ear...
