| May-29-17 | | Marmot PFL: 12 h3?? is very bad as just Qxg3 is good enough. |
|
| May-29-17 | | dark.horse: Easy, but not Monday easy. |
|
| May-29-17 | | Iwer Sonsch: Sally could have forced the positionally devastating Qh6 by playing 14...Qb6! (-3.98 @depth 28), for example 15.Nc3 Ng4 16.Re1 Qh6

No quick captures, but a won position.
After 14...Qc6, White could have prevented this line by playing 15.Nc3! Qe6 16.Qb3 Qc8 17.d3 (0.82 @depth 25). After 15.d4 Ng4, Black's last resort would have been 16.Qc2!. After trading Queens (16...Qxb5 17.Qxc5+ Qxc5 18.dxc5, Sally could have still won the exchange.

In this case, I'm just gonna play the role of <Jimfromprovidence>. White's decisive mistake was 12.h3?, allowing 12...Rxh3! (13.Bxh3 Qxg3+ #4). Instead, after 12.d4! Qxd4 13.Bxg5, White would have dominated (1.72 @depth 25). White's superior positon resulted from Black's dubious opening with 4...e4!? and 6...h6?!, which got easily refuted with 7.cxd5 hxg5 8.dxc6 (1.43 @depth 24) or 7...Nxd5 8.Ngxe4 (0.88 @depth 25). Instead, White's 6.Nc3!? allowed Sally to equalize with 6...d4, when play might have continued 7.Nd5 Nxd5 8.cxd5 Qxd5 9.d3 Bb4+ 10.Kf1 Qd8 11.Nxe4 O-O =. |

|
| May-29-17 | | mel gibson: The obvious move was
16... Qh6
but it doesn't work.
That pesky bishop blocks black.
The text
16 ... R-h1+
is mate in 4. |
|
| May-29-17 | | mel gibson: If only white wasn't so greedy by taking the bishop -
white just had to protect that f2 pawn with his Queen -
then the computer says:
16. dxc5 (16. Qc2 (♕a4-c2 ♔f8-g8 d4xc5 ♘g4-e5 ♖f1-d1
♕c6xb5 b2-b4 ♘e5-f3+ ♗g2xf3 e4xf3 c5-c6 ♗b7xc6 ♗c1-b2 g5-g4 ♕c2-c3 ♖h8-h7)
-0.74/17 131)
score for white -0.74 depth 17 |

| May-29-17 | | Iwer Sonsch: After <4...e4!? 5.Ng5 d5> (best move) <6.dxc5! Qxd5 7.d3>, Stockfish suggests <7...Bb4+ 8.Nc3 Qe5 9.Nxe4 Nxe4 10.Bxe4 Bh3>

|
| May-29-17 | | Iwer Sonsch: <mel gibson> Now compare to my line. |
|
| May-29-17 | | Walter Glattke: A less good win way was found with 16.-Nh2 e.g. 17.Rd1 Nf3+ 18.Kf1 Ba6 or 17.Nb3 Qxa4 18.Nxa4 Nxf1  |
|
| May-29-17 | | Pasker: Definitely not Monday puzzle..good for a Tuesday. I have seen this rook sac followed by mate in two many times but not this one. This is a little bit deeper. Rh1+ is a deflection tactic it deflects the bishop from the 7th rank so mate sequence can be executed without any interruption. Mate comes F2 which would not be possible after 16...Qh1. Nice one and I liked it. I could be very useful in my games. |
|
| May-29-17 | | Walter Glattke: corr: 17.Nc3 |
|
| May-29-17 | | patzer2: Looking at today's Monday puzzle (16...?), I figured both 16...Rh1+ and 16...Qh6 look to be winning. However, 16...Qh6 17. Re1 Bc6! is obviously more complicated and doesn't lead to a quick mate. So I picked 16...Rh1+ any 17. Qh6 with a simple mate-in-two to follow. The computer indicates 16...Qh6 wins after 16...Qh6 17.Re1 Qh2+ 18.Kf1 Bc6 19.Qb3 Rb8 20.a4 Ne5 21.Qd1 Nf3 22.Nd4 (22.Bxf3 exf3  ) 22...Bb7 23.b4 Qg1+ 24.Ke2 Qxg2 25.Bb2 Rh2 26.Rf1 Bd5 27.Nxf3 Bc4+ 28.Kd2 exf3 29.Bd4 Bxf1 30.Qxf1 Qxf2+ 31.Qxf2 Rxf2+ 32.Kc3 f6 (-5.08 @ 27 depth, Stockfish 8.) White's game takes a nosedive after the passive 12. h3? allowing the surprisingly strong demolition 12...Rxh3!  to (-2.24 @ 28 depth, Stockfish 8.) Instead, 12. d4! Qxd4 13. Bxg5 Re8 14. Rac1  to (+1.79 @ 34 depth, Stockfish 8) is close to winning for White. |
|
| May-29-17 | | patzer2: One reason 12...Rxh3! is so strong is the Rook is poison. After 12...Rxh3! 13. Bxh3??, Black has mate-in-four with 13...Qxg3+! 14. Kh1 Qxh3+ 15. Kg1 Ng4 16. Qe8+ Rxe8 17. a3 Qh2#. |
|
| May-29-17 | | Walter Glattke: A "Labrador kibitzer" question: why not winning a second pawn with 11.Bxe5 instead of 11.0-0!? Any refutation? I don't see one. |

 | | Sally Simpson: I failed to get this.
It's too hard for a Monday. Should be a Saturday problem at the very least. Hi Morf,
"Sally's Immortal."
Not quite. It's still this one.
G Chandler vs R Ratcliff, 1983 
click for larger viewThree pieces down. First was a theoretical bad move, 2nd was a complete blunder, 3rd was desperation. Then I sac my Queen. |
|
| May-29-17 | | Walter Glattke: The trick is, that11.Bxe5 Nxe5 12.Nxe5
f5!! could be parried, so I saw just, with 13.Nxc5 Bxh1 14.Ne6+!! - not easy to see. |
|
May-29-17
 | | Fusilli: Nice finish, Sally! |
|
| May-29-17 | | Walter Glattke: Congrats to the immmortal queen sac, but the computer possibly would play "coldblooded" like a stockfish, with 21.-Ne3 22.Rf8+ Ke7 23.Rxd8 Rxd8
24.g7xh8Q Nd1, but then the queen get some pawns on 7th raw. |
|
| May-29-17 | | Iwer Sonsch: <Larbador Kibitzer> Both are equally giving away White's advantage, given Black finds the objectively best response. The strongest options are 11.d3, 11.d4 or 11.Nxe4. |

| | Sally Simpson: If you guys keep running my games though a computer you will only end up blowing one of it's fuses as it tries to give an eval against me of -99999999999.99 |
|
| May-29-17 | | Iwer Sonsch: <Sally Simpson> Or it will just display #-130. |
|
| May-29-17 | | Walter Glattke: Yes, the continuations show, that 11.Nxe4 Bxe4 12.Bxe4 moves the rook and not -f5, and 11.d4 is a good Gambit with
11.-Qxd4 12.Qxd4 Bxd4 13.Bxg5 Ng4, so white is not developed. |
|
| May-29-17 | | BOSTER: Is this really a win after 23...Rh8 retreated?
For ex. 14 Qd1. |
|
| May-29-17 | | Iwer Sonsch: Oh. In my first analysis, the 15.Nc3! line is -0.82 (Black still has the advantage). |
|
| May-31-17 | | kevin86: mate follows with the queen. |
