Mar-04-18  SpamIAm: Also possible was 5...f6. Awkward-looking but Smyslov played it against Dely at Szolnok, 1975 (0-1, 40 moves). Smyslov played the 3...g6 defense in three other games at that tournament, winning twice more and drawing once for a total of 3&1/2 points out of 4 games. Dely vs. Smyslov, 1975

Mar-04-18  Grandma Sturleigh: <<computer chess guy>: Quite entertaining. More usual is 7. .. dxc6 but .. Qb4+ doesn't look bad. However, after 9. Ba4, 10. .. Qxa2 was a safer move for Black. After 10. .. b5?, Motylev launched an excellent counterattack.>

9. Bd5 (in place of 9. Ba4) prevents the Qxa2 defence. According to Stockfish this gives White a winning attack (more than +3 at depth 30).

Mar-04-18  patzer2: Impressive (12. ?) Sunday puzzle! The game continuation 12. Nxd4!! +- (+3.24 @ 31 ply, Stockfish 8), a deep combinational sacrifice of a Knight for two pawns while an exchange down, certainly wasn't on my radar.

Instead, as a senior citizen who fondly remembers the days when a Queen was worth ten points and the equivalent of two Rooks, I went for the win of the Black Queen with 12. Qd2.

Stockfish 8 evaluates 12. Qd2 +- (+2.16 @ 31 ply) as a second best move and a win for White after its best play line 12.Qd2 Ne7 13.cxd4 c4 14.Bxc4 bxc4 15.Nc3 Qxf1+ 16.Kxf1 +- (+2.66 @ 33 ply) when play might continue 16...O-O 17.Qf4 f6 18.Qd6 Rf7 19.d5 g5 20.Nd2 a5 21.Kg1 Ba6 22.Qxd7 Ng6 23.Qa4 Ne5 24.Qxa5 Rfa7 25.Qb4 Kf7 26.Nf1 Bc8 27.Ne3 Rb7 28.Nb5 +- (+4.00 @ 31 ply).

P.S.: Black's decisive mistake appears to be 10...b5?, allowing White to lock the Queen out of play for the rest of the game with 11. Bb3! +- (+3.28 @ 30 ply, Stockfish 8). Instead, 10...Qxa2 11. Qxd4 f6 12. e5 Qe6 13. Re1 Kf8 14. Nbd2 d6 15. exf6 Qxf6 16. Qc4 Qf7 ± to +- (+1.46 @ 28 ply, Stockfish 8) improves Black's survival chances.

Earlier, 7...dxc6 8. Qxd4 ⩲ to = (+0.19 @ 29 ply, Stockfish 8) improves over 7...Qb4+? 8. c3! ± to +- (+2.22 @ 32 ply, Stocisfish 8) where it appears Black is caught in an opening trap.

Mar-04-18  morfishine: Lovely attack by White! There appears to be a number of winning lines. I started with 12.Bxf7+ and got a persistent attack

After 12...Kxf7 (though this is not forced) 13.Qb3+ c4 14.Qxb5 and White has the immediate threat 15.Qd5+ picking up the rook on <a8>

An ongoing side threat is picking up the other took on <h8> which highlights the Queen's power being able to switch dangerously between diagonals

Mar-04-18  Marmot PFL: Looks like some heavy duty opening prep by white. Best to avoid these lines unless you have limitless time to study opening theory.
Mar-04-18  morfishine: <Marmot PFL: Looks like some heavy duty opening prep by white. Best to avoid these lines unless you have limitless time to study opening theory> Thats why I favor Chess960 these days: This format foregoes the requirement for "limitless time to study opening theory"

lol

Mar-04-18  Marmot PFL: <morfishine> Well black could have played 7...dc6 with an acceptable game G Guseinov vs Carlsen, 2017 but instead he had to get greedy.
Mar-04-18  morfishine: <Marmot PFL> Yessir, very well summed up, looks like either it was Black who had "prepped", but not deeply enough, or it was Black who thought he could figure it out OTB

BTW: Thank you for the game, a great example of just how strong Carlsen is tactically

Mar-04-18  agb2002: White has a knight for a rook and two pawns.

Black threatens c4 and dxc3.

I've considered 12.Bxf7+ (with the idea Qb3+, Ne1 and Nc2 to trap the black queen), 12.Nxd4 (with the idea 12... cxd4 13.Qxd4 f6 14.Qd5 Rb8 15.Qf7+ Kd8 16.Qg7) and 12.Bd5 Rb8 13.Nxd4 (with the idea 13... cxd4 14.Qxd4 f6 15.Qxa7.

I'm not sure but I'd play 12.Bd5.

  Jimfromprovidence: Here is the position after 12 Nxd4, below.

It appears that if black did not try to take the knight the plan was 13 Nxb5 with maybe 14 Qd5 in mind.

So black could have played 13...a6 or 13...Rb8 making it more difficult for white. Instead 13...cxd4 made it easy for white in retrospect.

Overall, it's a really difficult problem. The OLGA/Stockfish tool helps my understanding in that regard.

  penarol: What if 16...0-0-0 instead of Nh6?
Mar-04-18  agb2002: Stockfish doesn't like 12.Bd5 followed by 13.Nxd4 due to 13... Ne7 with a large advantage for Black.

  penarol: Now I see: 16...0-0-0. 17 Qc5+ and 18 Nb5
Mar-04-18  agb2002: <Jim ...

Instead 13...cxd4 made it easy for white in retrospect.>

13... cxd4 loses even after 12.Bd5 Rb8 13.Nxd4.

Mar-05-18  wtpy: Got the first 2 moves but then went with 16 Qd5, which yields winning advantage but not as decisive as e5.

Mar-05-18  njchess: Nice puzzle. Black has committed his queen to capturing material, but instead, finds his queen sidelined. Right away, I liked putting White's queen into the middle of the board via ♕xd4. So, the idea of 12. ♘xd4! was appealing, but I wasn't sure if Black would/should recapture or play 12. ... c4. The pawn push leads to White threatening with Knight, Queen and Rook with Black's queen still stuck in the corner.

So, 12. ♘xd4! cxd4 13. ♕xd4 f6. I quickly found the quiet but crushing move of 14. e5 This pawn move opens everything up for White. Black has to scramble to develop, keep his king out of check and not lose more material. Good luck! Time to check.
