Assumimg that Stockfish really sees the 50 move rule here, it should but I can't remember Stockfish actually doing this myself, but then it will find that every value other than a draw is wrong. Because even with only three pieces moving there are a lot of transpositions all with the same value beca...

23. Qxh5 is totally winning by the way, as most people already will have seen by now. But Stockfish practically only considers the reply 23. Bxh5 which is not winning 1rb1qrk1/2b2pp1/p3pB2/3pPnPp/1ppP4/2P4Q/PP3P1P/R2BR1K1 w - - (best 15 moves here) 1rb1qrk1/2b2pp1/p3pB2/3pPnPp/1ppP4/2P4Q/PP3P1P/R2BR...

After ten hours (one core) latest Stockfish development version is still playing something else, 21. h3 At no point 21.

I think there is an aging factor for the stat scores, so that they do get refreshed. But more importantly, the bonus is only added in nodes with no ttHit. This means probably that the node is often near the leaves, and a new node. Once the hash probe finds a search result, you have both a search res...

As far as I can see, those are good questions. Using the alternative Key I think is no longer needed but still there because in the past the result of the search with excluded move was stored, but it gave a little Elo not to do that anymore. I can't really see why it was not smplified away after tha...

E-mail from New in Chess about Larry Kaufman's new book, I just saw this in my mailbox, maybe interesting idea for the people looking for a gift to themselves or for others for the holiday season. You indirectly support work on Komodo, and Monte Carlo search I think too. https://gallery.mailchimp.co...

Yes, after all the engines are giving an advantage of over 1.00 to White. The question is whether Black can draw. If Black is worse after 16. g3 but not losing, one can argue about whether the word "unsound" really applies to Black's play. Hello Jean Paul, sorry, I missed your reply here! No sure s...
