|Feb-07-18|| ||FSR: 14...Ba6! (threatening ...Qxa8) 15.Bxd8 b4+ 16.c4 Bxc4#.|
|Feb-07-18|| ||ASchultz: I went with Ba6 even though Qxb7 staves off the ...b4 mate forcing the bishop off the diagonal. I figured the central pawn roller and 2B's were too powerful, and Fritz backs me up. While White can probably play b4 to stop mate, there's still the matter of the active knight.|
I figured there was a better move, since this was a puzzle and all, but I couldn't see it. Or, rather, I saw it, and I didn't see it could be played right away. I suppose some "why wait to make a big splash" self-help gurus would slap me on the wrist for not considering ...b4 right away once I saw the idea. I just fixated on piece development first.
Fritz also gives ...Qe8 as a win. The threat of ...d5, ...Bf5 and Bd3# is surprisingly strong. Wild stuff!
|Feb-07-18|| ||saturn2: I saw 14..Ba6 15 g3 (otherwise soon mate) QxQa8|
|Feb-07-18|| ||WorstPlayerEver: <wtpy>
Lol I did not read your answer before posting. Quite odd :)
|Feb-07-18|| ||agb2002: Black has a bishop and three pawns for a rook and a knight.|
White threatens Bxd8.
The white king can move to e2 only and the white queen is defenseless. Therefore, 14... Ba6, with the double threat b4+ and mate next, and Qxa8:
A) 15.B(Q)xd8 b4+ 16.c4 Bxc4#.
B) 15.Qb7 Bxb7 16.Bxd8 Bxd8 - + [2b+3p vs R+N].
C) 15.b3 Qxa8 - + [q+b+3p vs R+N].
Another option is 14... Qc7 but White has 15.Be7 followed by Bd6.
The alternative 14... Qe8 is met with 15.Qb8 Qe6 16.Qd6.
I think I'd play 14... Ba6.
|Feb-07-18|| ||patzer2: Count me among the crowd that went with 14...Ba6 -+ (-4.29 @ 29 ply, Stockfish 8) in attempting to solve today's Wednesday puzzle. |
Stronger alternatives are the game move 14...b4 -+ (-15.27 @ 27 ply, Stockfish 8) and 14...Qe8 -+ (-8.90 @ 28 ply, Stockfish 8).
P.S.: White's first near losing move appears to be 8. dxc6?, potentially allowing 8...exf2+ -+ (-1.86 @ 31 ply, Stockfish 8).
Black missed the initial winning move 8...exf2+ -+. However, given a second opportunity after 8. dxc6? bxc6 9. h4?, he didn't miss the decisive 9...exf2+ -+ (-2.61 @ 28 ply, Stockfish 8).
Instead of 8. dxc6?, White should have played 8. Bxe3 Bxe3 9. Ne6 ⩱ (-0.30 @ 28 ply, Stockfish 8). Instead of 9. h4?, White could have minimized the damage with 9. Bxe3 Bxe3 10. Bxc6 Rb8 11. Ne4 ⩱ (-0.49 @ 28 ply, Stockfish 8).
Earlier in the opening, in lieu of the rarely played 6. Ng5 = White IMO is better off with the popular move 6. Bxc6 ⩲ as in White's win in Anand vs L'Ami, 2017.
|Feb-07-18|| ||agb2002: 14... b4 is far stronger than 14... Ba6 because White only seems to have 15.Qxc8 (15.c4 Ba6 16.Nbd2 Qxa8).|
|Feb-07-18|| ||Pedro Fernandez: Yeah <Sharky> 14...b4. But I did play 14...Ba6 as I didn't see 15.Qb7. Nevertheless, there is not machine who can defeat you with my move! Greetings!|
|Feb-07-18|| ||Walter Glattke: 15.Qxa7!? Bxa7 16.Bxd8!? Ba6# / 15.Qxc8 Qxc8 16.c4 Queen and 3 pawns for rook and knight -+|
|Feb-07-18|| ||AlicesKnight: Found it after a bit - most of the action appears to be elsewhere which distracts at first....|
|Feb-07-18|| ||cocker: A wonderfully wild game.|
|Feb-07-18|| ||mel gibson: The move that led to this puzzle is more interesting.|
Stockfish 8 didn't see it.
(14. c4 (c3-c4 b5-b4) -11.38/28 150) 14. .. b4
score for Black -11.38 depth 28 time = 150 seconds.
However when you give Stockfish 8 the great move:
it sees that it's better:
(14. .. b4 (b5-b4)
Score for white +15.77 depth 29 - time = 150 seconds.
I tried this with other engines as well and they didn't see
14. Bg5 either.
So White played a brilliant move better than a chess engine!
|Feb-07-18|| ||saturn2: What is brilliant about 14 Bg5?|
|Feb-07-18|| ||mel gibson: <Feb-07-18 saturn2: What is brilliant about 14 Bg5?>|
Even a chess engine rated much higher than a grand master 3350
didn't see that move.
|Feb-07-18|| ||gofer: Queen Trap! I looked at the immediate <14 ... Ba6>, but it seems
to come unstuck against <15 Qb7!>...|
14 ... Ba6
15 Qb7! Bxb7
16 Bxd8 Ba6
So instead I think we play the threat of the queen trap
and also the threat of the mate and leave Ba6 for the next move...
<14 ... b4!>
White can resign!
15 Bxd8 Ba6+ mating
15 Nbd2/Ned2/Nxf2 Ba6+ winning the queen
15 Nf6+ gxf6 winning the queen with Ba6 next move
15 c4 Ba6 winning the queen
Yep, much nice than <14 ... Ba6>
|Feb-07-18|| ||saturn2: <mel gibson> So white wins after 14 Bg5?|
|Feb-07-18|| ||mel gibson: <Feb-07-18 saturn2: <mel gibson> So white wins after 14 Bg5?>|
+15.77 is a good score!
|Feb-07-18|| ||RandomVisitor: <patzer2>Thanks for your computer analysis using Stockfish 8. |
Did you know that Stockfish 9 is now out? It is a bit stronger than Stockfish 8, and the chess community here could benefit somewhat from your frequent, continued postings using a free, stronger engine.
|Feb-07-18|| ||hemy: Both players names returned me the memories from different time periods.|
First time I met Karen Grigorian in person in 1963. It happen during Soviet Union High school Spartakiad in Baku (Azerbaijan). I played on 1st board of Lithuania team (5.5/8) and he on the 1st board of Armenia.
Karen was coming to the Lithuanian team room to spend time playing blitz, cards and socializing. We met on the chess board on July 1967 in the 10th Soviet Team Chess Championship , Moscow. His result was 5/8, my was 4.5/8. He won against me:
K Grigorian vs N Kasimov, 1967
With Roman I met in December 1978.
I won this game, that was the most memorable game in my life:
N Kasimov vs Dzindzichashvili, 1978
|Feb-07-18|| ||Pasker: White attacks blacks queen with the powerful looking Bg5 only to lose his own queen. Simple b4 c4 (or checkmate) Ba6 (threatening Bxc4#) wins the Q.|
|Feb-07-18|| ||malt: Have gone for
14...b4 15.c4 (15.Q:c8 Q:c8)...Ba6 16.Nbd2 Q:a8
|Feb-07-18|| ||morfishine: While 14...b4 can be met by the prolonging (but not changing the result) move 15.c4, best is the brilliant Queen sac <15.Qxc8> and the battle rages with unrestrained fury|
well, the game continues for awhile
|Feb-07-18|| ||Cheapo by the Dozen: I actually had some problems Mon/Tue, but I nailed this one.|
Step 0: Look for mate threats. Fail to find any.
Step 1: Check whether ... Qc7 works. Figure out that Be7/Bd6 is a successful counter.
Step 2: Look again for mate threats. Find ... Ba6.
Step 3: See that it also provides a discovered attack against the queen. Observe that this could be to the benefit of Black's rook and queen alike, and that ... Qxa8 would of course save Black's queen from being captured herself.
Step 4: Check ... b4 as a double threat (mate or discovered attack on the queen). See that it only has one defense that counters both threats, namely c4.
Step 5: Check whether there's a clear win after 14 ... b4 15 c4. It turns out that there is, because the discovered attack 15 ... Ba6 also renews the mate threat. Done!
