And some highlights.
[d]rnbqkbnr/ppp2ppp/8/3pp3/8/3PP3/PPP2PPP/RNBQKBNR w KQkq - 0 3
The type of opening you need against Stockfish to win.
[d]r2q1rk1/5pp1/ppnbbn1p/2p1p3/2PpPP2/1P1P2PP/P5B1/RNBQ1RNK b - - 0 17
Whoever attacks first will usually win.
[d]1r3rk1/3b1pp1/p2b1n1p/qpp1pPP1/2PpP2P/1P1P4/P1nNQ1B1/R1B2RNK b - - 0 23
This is a position where every single move counts. Stockfish opens the h file and does not accept the rook sacrifice, but it is not clear if this is the right way to proceed.
[d]1r1q1rk1/3b1p2/p2bnPp1/1pp1p1P1/2PpP3/1P1Pn1RB/P2NQ3/1RB3NK w - - 0 30
This is already won for white, but I do not know if Stockfish sees it. What is most important is the open h file, which Stock somehow frequently underestimates. The h file with short castled enemy king is easiest of all to open because only the g pawn stops the enemy attack, and controlling it should be a bigger asset than usual.
[d]1r1q1rk1/5p2/p2bbPp1/2p1p1P1/2ppP3/1P1P2R1/P7/1RB2QNK w - - 0 33
Stockfish has just captured bc4. Here Rb2 wins easily of course.
[d]1r2r1kR/5p2/p4Pp1/2p1p3/3p4/1P3R2/P2p3Q/2B4K b - - 0 43
Stockfish is almost ready to promote a queen.

Well, why I posted that game? I do not know. Maybe just as a reference to those who would claim the current top engines have reached a climax and there is no going further. That is simply not so. Modern top engines play astounding chess, but they are still not immune to defeat. I think, just in terms of software, at least some 300 more elo points could still be gained, as chess is extremely rich.
On such a freezing December day, on a slightly optimistic note, I also think that not everything is lost for humans, and, Carlsen for example, after a couple of years' training at anticomputer strategy, could calmly challenge any of the top engines.
So much so. 1 win with a fair portion of draws (and many losses unfortunately...) per day, that will make 365 wins per year, not so bad after all for me.
I would like once again to thank Marco, Joerg, Gary, Reuven, Tord of course, and everyone else involved in the creation of a splendid and completely free chess engine! Stockfish is really great, it plays superb attacking and tactical chess, a precious stone in each chess enthusiast's collection.
Best, Lyudmil
