Re: A little more B30 Sicilian

Hi Stephen! Nice to see you posting here again! I think you are probably right, something along those lines like what Bent Larsen wrote and Stockfish not seeing the extra compensation, developmentwise probably. (I was watching The Apartment, nice 1960 comedy with Jack Lemmon and Shirley MacLaine, an...

Re: First ply of a big fail high. But it's looking grim for white

Thanks Jean Paul, interesting that this was actually a game. I think they may have used computers but not always typical computer moves, or at least not always what Stockfish would have played. But I only did a quick blundercheck. Then again, I don't know because a Savo Scanto on ICCF only is rated ...

Re: A little more B30 Sicilian

At depth 42 and the situation has not really changed. So even with depth to compensate for any gaps there might be in the positional evaluation of openings, still Stock does not like 3. d4 It is barely in seventh place again. No, eighth now, 3. a3 is now also better :wink: I do not like 3. Bb5 too m...

A little more B30 Sicilian

In relation to Ed's post, Stockfish really does not think much of standard opening theory here. 3. d4 gets close to a negative eval, even when using no contempt in UCI options. r1bqkbnr/pp1ppppp/2n5/2p5/4P3/5N2/PPPP1PPP/RNBQKB1R w KQkq - Engine: Kaissa IV NoContempt (512 MB) by T.

Re: First ply of a big fail high. But it's looking grim for white

Hoi Jean Paul, Yes you are correct on all counts :) This just the standard output of Shredder GUI. The last number is not really giving much information as it is just nodes per second on my machine, using one thread. Yes, not one PV possible, but many moves, all with a good score but none showing re...

Re: First ply of a big fail high. But it's looking grim for white

For me, I was mainly interested if there really was a win, a strong winning move as Dann seemed to expect, or a gradual one. Given a Queen against Knight and Bishop and pawn, or Queen and Rook against 4 light pieces, is Queen highly redundant with two Rooks and is there disadvantage of no light piec...

Re: First ply of a big fail high. But it's looking grim for white

With experimental Kaissa clone, the last three PVs have become more stable than before, but this is at a high depth, for Kaissa depth 45 but it does more extensions than anyone I think :lol: I have not really checked yet whether I have edited everything right in the Stockfish sources and this is its...

Re: Legal status of Eman?

An easy way to bring down the losses would be to include an opening book. You'd just copy Brainfish and maybe hide the the immediate moves. I don't want to investigate, this thing may not have a book at all but some others other do I believe? I understand people want to hobby and extensively documen...

Re: Little thought experiment

Mmm, if you set Stockfish to fixed depth 15 search but disable all extensions that would be close? Maybe still strong vs human GM but not really SF. 15 ply used to be the depth for the bench function I thought, although now it seems to be lower, just 13 ply, it tests most parts of the search in benc...
