|Jun-06-15|| ||gofer: The start is pretty easy, even though black is a whole rook down, exchanging off
the other one gives black complete control of the white diagonals, with tempo!
After sweeping off the other bishop black's bishop reign supreme and white's
rooks just look on dumbfounded...
<19 ... Rxc2+>
<20 Kxc2 Qc4+>
<21 Kd2 Bxd4> (21 Kb1 Bf5+ mating)
Black has traded down twice, but has a huge attack. Black threatens to simply sweep up
Pb2 and Pd5 without giving the white king any chance of reaching safety. White has to
find a decent response...
22 Rc1 Qxd4
22 Qd2 Bc3+
<22 Qf1 Qxd5>
Hmmm, I don't think white found the best defence. 22 Qf1 give white more chances of survival...
|Jun-06-15|| ||Viennablue: Would anybody have the grace to show the continuation after 28.Kh5 pls.?
First I went with 28...Qc8 with the idea Qe8 with mate. But 29.Qb5 seems to prevent this.
And the variations after 28...Bg6+ followed by h5+ have some depth... I can only see perpetuals...|
|Jun-06-15|| ||Caissalove: 28 Kh5 Bg6+ 29 Kg4 Qc8 mate|
|Jun-06-15|| ||jith1207: <Viennablue> are you looking for: 28.Kh5 Bg6+ 29. Kg4 Qc8# ?|
|Jun-06-15|| ||ninja warrior: if 28.Kh5 Qc8 29.Qb5, then 29...Bg6+ 30.Kh6 Qf8#
you were close to seeing it; you just had to combine your two ideas: the trick was in realizing that 28...Qc8 forms a battery with & frees the B to shut the trap.
2 of my favorite chess quotes pertain:
"chess is 99% tactics".
"tactics flow from a superior position".
|Jun-06-15|| ||jith1207: Apologize in my previous posts, I have confused white and black in multiple places.|
|Jun-06-15|| ||Viennablue: @ninja,jith: thanks!
Seems i missed a tuesday-level thing on todays saturday 😐
|Jun-06-15|| ||sfm: I am certain that 16.-,Rxc2+ would never have crossed my mind.
It is as much a 'bolt from the blue' move as anything I have ever seen. White's position looks completely healthy and solid, with two perfectly positioned bishops, with one of them dealing with Black's important Bg7, and even overprotected.|
White could of course simply have tried 17.Qxc2, as 17.-,Rc8 18.QxR+, appears to be at least 'quite safe'?!
|Jun-06-15|| ||morfishine: I have the Dragon book by Gufeld & Schiller (revised 2011) but this game isn't in it. Its probably due to <sfm>'s post where White improves with 17.Qxc2 Rc8 18.Qxc8+ Bxc8|
In any case, I thought <19...Rxc2+> was best but after 20.Kxc2 Qc4+ 21.Kd2 Bxd4 22.Qe2 I was unable to find 22...Bc3+
|Jun-06-15|| ||Once: A funny thing happens in this game. Black gets to create the same mating combination on at least three occasions but on different squares.|
Okay, that might sound a bit "crouching tiger, hidden dragon" So I had better explain.
Here is the basic mating pattern. The white king is caught in the centre of a web of black squares. It is as if he is standing on the central dot of the number 5 on a dice.

Sometimes known as a dovetail mate, and sometimes known by other names. That's not important right now.
We first come across this pattern after black's clever 22... Bc3+
click for larger view
Now 23. bxc3 would allow 23...Qxc3# and we have our first dovetail mate.
So instead the White king is forced to run away with 23. Ke3 Qc5+
click for larger view
And here we have the opportunity for another dovetail mate. If White tries to block the queen check with 24. Rd4 then 24...Qxd4# is the same pattern, but just a square higher up the board.
White has to run again with 24. Ke4 Bf5+:
click for larger view
It's not quite a dovetail, but the pattern is very similar. The White king is in the middle of a dice 5 pattern whilst being speared along the diagonals. Which sounds quite nasty.
25. Kf4 Be5+
click for larger view
And again. Not quite a dovetail, but similar.
And on it goes. Black hounds the white king with eight diagonal checks in a rapid sequence starting with 22... Bc3+.
A stunning finish. I saw the first couple of moves, but not the whole thing. Now it seems so obvious.
It's the third day of my novel giveaway. Details of a free book on my home page.
|Jun-06-15|| ||mrknightly: "Tejas Chainsaw Massacre"|
|Jun-06-15|| ||dfcx: White has an extra rook but can't use it. Its king is in the middle open to attacks. |
19...Rxc2+ 20.Kxc2 Qc4+!
A) 21.Kb1 Bf5+ and mate follows
B) 21.Bc3 Bxc3 22.bxc3? Qxc3+ 23.Kb1 Bf5+ and mate too.
C) 21.Kd2 Bxd4
C1) 22.Qe2 Bc3+ 23.Ke3 (bxc3? Qxc3#) Qc5+ 24.Kf4 (Kd3 Bb5+) Be5+ and white has to give up queen to avoid mate
C2) 22.Qf1 Bc3+ 23.bxc3 Qxc3+ 24.Ke2 Bb5+
C3) 22.Qe1 Qb3
C4) 22.Qg3 Bc3+ 23.bxc3 Qxc3+ 24.Ke2 Bb5+ and mates
|Jun-06-15|| ||jindraz: somewhat odd as a puzzle, since at the diagram position Black cannot reasonably do anything else besides Rxc2. The 16th move is the unbelievable one, and still harder to guess that 17. Bxc2 is the losing error|
|Jun-06-15|| ||kevin86: The exchange sac sends the white king on a 10 mile hike!|
Salute to D-Day (71 years ago today). The courageous invasion of Normandy that led to the Allied victory in WWII.
|Jun-06-15|| ||1 2 3 4: Definitely not "very difficult", got it all the way through 21 (stopped after that)|
|Jun-06-15|| ||jindraz: 1 2 3 4: not very difficult...the only difficult part was 16...Rxc2, and I do not play dragon and I suspect it is a standard theoretical sac. I looked at the endgame after 17. Qxc2 and it seems that neither side has anything since the white bishop at b3 is very passive. The curious thing is that after 17. Bxc2 Qxa2 White gets a breather but it does him no good.|
|Jun-06-15|| ||BOSTER: <goodevans: 22...Bc3+ is certainly a lovely move, but white seems to be playing into black's hands with 22.Qe2,cutting down the options for King's movement>.|
This is the pos. White to play 22.
click for larger view
Here white could play 22.Qf1.
And if black'd play the same <trick> 22...Bc3+, white could answer bxc3 23.Qxc3+ Ke2 24.Bb5+ Kf2 25.Bxf1 Rhxf1 and <sfm: An absolutely stanning> win is far away.
if 22...Qxd5 23.Ke1, and if Bb5 24.Rxd4.
|Jun-06-15|| ||agb2002: Black has a pawn for a rook.
White threatens 20.Bxg7 Kxg7 21.Qd4+ stopping the attack with a won game.
The position of both white bishops invites to play 19... Rxc2+ 20.Kxc2 Qc4+, recovering some material:
A) 21.Kb1 Bf5+ and mate in three.
B) 21.Kd2 Bxd4
B.1) 22.Qe1 Bxb2 threatening Bc3+ and to push the b-pawn looks winning. For example, 23.Qe4 Bc3+ 24.Ke3 Qc5+ 25.Ke2 (25.Kf4 Be5+ wins the queen) 25... Bb5+ 26.Rd3 b3 27.Qxe7 Bxd3+ 28.Kxd3 Qd4+ 29.Ke2 Qd2+ 30.Kf1 b2.
B.2) 22.Qe2 Bc3+
B.2.a) 23.bxc3 Qxc3#.
B.2.b) 23.Kc1(2) Qxe2 wins decisive material.
B.2.c) 23.Ke3 Qc5+
B.2.c.i) 24.Kd3 Bb5+ wins the queen.
B.2.c.ii) 24.Ke4 Bf5+ 25.Kf4 Be5+ 26.Kg5 f6+ 27.Kh4 (27.Kh6 Bf4#) 27... g5+ 28.Kh5 Qc8 and mate soon.
B.2.c.iii) 24.Kf4 Be5+ 25.Kg5 (25.Ke4 Bf5#) 25... f6+ looks similar to B.2.c.ii.
B.3) 22.Qf1 Bc3+ 23.bxc3 (23.Ke3 looks similar to B.2.c) 23... Qxc3+ 24.Ke2 Bb5+ 25.Kf2 Bxf1 26.Rhxf1 b3 - + [Q+2P vs 2R]. The rooks are tied to the first rank due to the promotion threat. This means that Black's royal family has enough freedom to win the ending.
B.4) 22.Qg3 Bxb2 threating Bb5 and to push the b-pawn looks winning. For example, 23.Qg5 Bb5 24.Ke3 (24.Rde1 Qd3#) 24... Qe2+ 25.Kf4 Be5+ and White will lose the queen to stop mate.
C) 21.Bc3 bxc3
C.1) 22.b3 Bf5+ 23.Kc1 Qxb3 looks winning,
C.2) 22.Rd3 Ba4+ wins.
C.3) 22.Qf1 Ba4+ wins.

Can't say I'm entirely convinced about today's puzzle. 22 ... Bc3+ is certainly a lovely move, but white seems to be playing into black's hands with 22 Qe2, cutting down the options for his king’s movement. Surely there was something better at this point?>
22. Qf1 was better, but black plays ..Bc3+ all the same. White can capture 23. bxc3 but after .. Qxc3 24. Ke2 Bb5+ skewers the white Q.
Black ends up with Q versus two Rs, and the passed b-pawn will ensure the win.
