Stockfish mates Allie in 34 moves / TCEC

Post by Jouni » Tue Oct 01, 2019 12:13 pm


Allie took 74 min for 32.-Bg5, but didn't found escape :P . Obviously NN engines missed 25.Ra6 totally.

Fantastic Game by Stockfish ( A Masterpiece) These queens indian sac lines can be quite hard to defend (LC0 and Alpha Zero still keep playing both sides of these lines though) move 11. Ng5!....Move 16. h4!!...Move 18. e5!! Move 25 Ra6!! Move 28. Rh6!! High Quality Finishing Indeed! AR :) :wink:

Yes, very nice game indeed. Latest Leelenstein with PR925 thought 21. ... Nh5?1 was doubtful and that black had better chances with 21. ... Bxd5.

Actually, Cfish is not seeing much gain in evaluation here. Can Black still draw?

If we substitute your line of play starting at 21.... Bxd5 we get this:



Other possible moves instead of 32. … a5 are 32. … Kg7 and 32. … Kh7 both of which seem worse.

The a5 line looks something like this:

Code: Select all

( [Stockfish 240919 64 BMI2] 55:+3.16 32...a5 33.Bc6 Re6 34.Rd8+ Kg7 35.Bb5 Re5 36.Be2 Rb2 37.Bc4 a4 38.bxa4 Rc5 39.Be2 b3 40.Bf4 Ra2 41.Rb8 b2 42.Ke3 Rf5 43.Bd3 Ra3 44.Ke2 Ra5 45.Rxb2 R3xa4 46.Ke3 Rd5 47.Be4 Rc5 48.Rb7 Ra3+ 49.Kf2 Raa5 50.Bd3 Rxg5 51.Bxg5 Rxg5 52.Bc4 Rf5+ 53.Ke3 Rf6 54.Rc7 Kg8 55.Ke4 Kf8 56.Rb7 Rf2 57.Ke3 Rf6 58.g4 )
 
This looks winning to me.

There is a chance that one of the black moves between 21. … Bxd5 and 32. … a5 could improve blacks situation. I haven't looked an any of them in depth. If none do then I believe black is lost.

Here is a postmortem reverse analysis done with (now old) stockfish 10 at depth 30 with 4 threads.
The following moves by Allie look wrong:
16. .. b4 is probably losing
21. .. Nh5 is certainly losing
23. .. Qd7 is definitely losing
Note also that Allie played badly the endgame, the mate should have occurred later.
