A tactical position SF is struggling!

Post by Nay Lin Tun »

I copied this tactical position from other forum. OP says, the solution is Nxg7. [d]r1r3k1/1bq1bppp/p1npp3/2nB1NP1/1p2P3/2N1B1R1/PPP1QP1P/2KR4 w - - 0 1

Strange, LC0 in my laptop see it in 5k nodes (9 seconds on slow gpu) or she will probably find it in 0.5 sec fast gpu.
On the other hand, SF 10 could not find it at 1.3 billion nodes , 3 mins in my laptop.

Please let us know when LC0 finds the best move, which is Rh3. :twisted:

Here's the original game:
[pgn][Event "Russian Club Cup"] [Site "?"] [Date "1998.06.03"] [Round "?"] [White "Fedorov, Alexei"] [Black "Kobalia, Mikhail"] [ECO "B57"] [WhiteElo "2595"] [BlackElo "2500"] [Result "1-0"] 1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 Nc6 6. Bc4 e6 7. Be3 a6 8. Qe2 Qc7 9. O-O-O Be7 10. Bb3 O-O 11. Rhg1 Nd7 12. g4 Nc5 13. Nf5 b5 14. Bd5 Bb7 15. g5 Rfc8 16. Rg3 b4 17. Nxg7 Kxg7 18. Qh5 Rg8 19. Bxe6 bxc3 20. Bxf7 Qa5 21. Rh3 Kf8 22. Rf3 Ne5 23. Bd5+ Kg7 24. Rf7+ 1-0[/pgn]

19...bxc3 is a game-losing blunder.

I think Ng7 is just better for black

Quite right.
After 17.Nxg7(?) and some Forward- Backward:

[d]r1r3k1/1bq1bpNp/p1npp3/2nB2P1/1p2P3/2N1B1R1/PPP1QP1P/2KR4 b - - 0 1
Analysis by MZfish 1.0 64 POPCNT:

17...Kxg7 18.Qh5 Rg8 19.Bxe6 Nxe6 20.Nd5 Qd8 21.f4 Kh8 22.Qxf7 Qc8 23.Nxe7 Nxe7 24.Qxe7 Bxe4 25.Bd4+ Nxd4 26.Qxe4 Nf5 27.Rh3 Ra7 28.Rd5 Rf8 29.Qxb4 Qe6 30.Re5 Qf7 31.Ra5 Rc7 32.Rc3 Re7 33.Rd3 Rc8 34.b3 Rec7 35.Rd2 Qe6 36.Kb2 Kg8 37.Rxa6 Qe1 38.c4 Qe4 39.Rd5 Qxf4 40.Qd2 Ne3 41.Raxd6 Nxd5 42.Qxd5+ Kh8 43.Qd4+ Qxd4+ 44.Rxd4
-/+ (-1.52) Depth: 40/75 00:04:31 5560MN

And after 17.Rh3(!) and corresponding FW- BW again:

[d]r1r3k1/1bq1bppp/p1npp3/2nB1NP1/1p2P3/2N1B2R/PPP1QP1P/2KR4 b - - 0 1

Analysis by MZfish 1.0 64 POPCNT:

17...g6 18.Nh6+ Kg7 19.Bxc6 bxc3 20.Bxb7 Qxb7 21.b3 Nxe4 22.Qf3 Rf8 23.Qg4 Rac8 24.Qh4 Rh8 25.f3 Nd2 26.Qf4 Rhf8 27.Qh4
= (0.00) Depth: 40/63 00:07:08 8827MN
17...g6 18.Nh6+ Kg7 19.Bxc6 Bxc6 20.Qf3 Be8 21.Nf5+ Kg8 22.Nh6+
= (0.00) Depth: 41/21 00:09:21 11604MN

Could well lead to more or less forced 3fold by checks repeated, whilst ...Nxg7 is still Black's advantage yet.

Could well lead to more or less forced 3fold by checks repeated, whilst ...Nxg7 is still Black's advantage yet.
Yes, Cfish-dev sees nothing better than 0.00

0.00 17. Rh3 g6 18. Nh6+ Kg7 19. Bxc6 Bxc6 20. Qf3 Be8 21. Nf5+ Kg8 22. Nh6+ (depth 59, 4:56:10)

Strange, LC0 in my laptop see it in 5k nodes (9 seconds on slow gpu) or she will probably find it in 0.5 sec fast gpu.
On the other hand, SF 10 could not find it at 1.3 billion nodes , 3 mins in my laptop.

Please let us know when LC0 finds the best move, which is Rh3. :twisted:

http://www.talkchess.com/forum3/viewtop ... =2&t=50369

Here's the original game:
[pgn][Event "Russian Club Cup"] [Site "?"] [Date "1998.06.03"] [Round "?"] [White "Fedorov, Alexei"] [Black "Kobalia, Mikhail"] [ECO "B57"] [WhiteElo "2595"] [BlackElo "2500"] [Result "1-0"] 1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 Nc6 6. Bc4 e6 7. Be3 a6 8. Qe2 Qc7 9. O-O-O Be7 10. Bb3 O-O 11. Rhg1 Nd7 12. g4 Nc5 13. Nf5 b5 14. Bd5 Bb7 15. g5 Rfc8 16. Rg3 b4 17. Nxg7 Kxg7 18. Qh5 Rg8 19. Bxe6 bxc3 20. Bxf7 Qa5 21. Rh3 Kf8 22. Rf3 Ne5 23. Bd5+ Kg7 24. Rf7+ 1-0[/pgn]

19...bxc3 is a game-losing blunder.
Indeed, 17. Nxg7 is certainly playable OTB, as the waters appear to be shark infested. Plenty of opportunities for black to commit a fatal mistake here.
