|
| Sep-09-15 | | agb2002: The material is complete.
White threatens 13.fxe4.
The move f3 has weakened the dark squares around the white king. This suggests 12... Bxh2+: A) 13.Kxh2 Qh4+ 14.Kg1 g3 followed by 15... Qh2#.
B) 13.Kh1 Bg3 14.Kg1 Qh4 15.Rf2 Bh2+ 16.Kf1 (16.Kh1 Ng3# or Nxf2#) 16... Ng3# or Qxf2#. |
|
| Sep-09-15 | | stst: QNP will deliver (Main line only):
12.............. Bxh2+
13.Kxh2 Qh4+
14.Kg1 g3
15.Rf2 gxf2+
16.Kf1 Ng3+
17.Kxf2 Nh1+
18.Kf1 Qf2
Too tired to give variations in between. |

 | | Phony Benoni: If White plays out the <12...Bxh2+ 13.Kxh2 Qh4+ 14.Kg1 g3 15.Rf2 gxf2+ 16.Kf1 Qh1+ 17.Ke2> variation:

|
| Sep-09-15 | | Coriolis: I thought the key move; if 13. Kxh2 was played, would be 13... g3+ followed by 14...Qh4. |
|
| Sep-09-15 | | gofer: <12 ... Bxh2+>
Refusing loses in three more moves...
13 Kh1 Qh4
14 Rf2 Ng3#
14 Nxe4 Bg3+
15 Kg1 Qh2#
14 g3 Bxg3+
15 Kg1/Kg2 Qh2#
Accepting is a nice forced mate in 5 moves...
<13 Kxh7 Qh4+>
<14 Kg1 g3>
<15 Rf2 gxf2+!>
<16 Kf1 Qh1+>
<17 Ke2 f1=B#>
Setting the bits up at this point is a nice little puzzle for a
beginner...

Yep... |
|
| Sep-09-15 | | morfishine: The ole Bishop take the h-pawn check: 12...Bxh2+ 13.Kxh2 Qh4+ 14.Kg1 g3 or 13.Kh1 Qh4 <perfidious> interesting point ***** |
|
| Sep-09-15 | | saturn2: Full board, with all pieces and pawns. Maybe it was a kingindian? No, in this I was wrong. But I got the right continuation:
Bxh2:
If white takes then Qh4+ and g3.
If white does not take then black can also play Qh4 in the second move and Bg3 next. |
|
| Sep-09-15 | | patzer2: Took me a few minutes, but after I gave up on trying to make 13...Qh4 14. f4! Nf6 = work I went for the Wednesday puzzle solution 13...Bxh2+! Fritz indicates 13...Bxh2+! forces mate-in-five or less, as given in <dfcx>'s post. White's decisive error was 12. f3?? Instead, 12. Nxe4 = holds as play might continue 12...dxe4 13. Be2 Qh4 14. g3 Qh3 15. Kh1 Rf6 16. Rg1 Rh6 17. Rg2 Nf6 18. Qb3 = (+0.20 @ 23 depth, Deep Fritz 14). |

| Sep-09-15 | | Once: A QGD? I'd call that a stonewall Dutch. Admittedly we get there by transposition, but it's looking very Dutchy to me. The interesting sequence for me is g5-g4 by Black. We are taught not to disturb the pawns in front of our king, but this is a modern twist. Black's plan is to kick the white knight from f3 and then do unspeakable things to h2. Black gets away with this because he has control of the centre and can funnel more pieces to the kingside than white can. But his plan has to work fairly quickly or he is going to suffer from having a bad bishop on c8 and a Billy-no-mates rook on a8. This is the sort of attack that we Dutch defence players dream of. Knight on e4, kingside pawns rushing forwards, Queen fast forwards to the h file, White playing punchbag. |
|
| Sep-09-15 | | CHESSTTCAMPS: It appears that white has just played 12.f3, when f4 was necessary to close the king-side. Now white's weak dark squares can be exploited by a routine combination: 12... Bxh2+ 13.Kxh2 (Kh1 Qh4 forces mate in two) Qh4+ 14.Kg1 g3 15.Rf2 gxf2+ 16.Kf1 Qh1+ 17.Ke2 f1=Q# |
|
| Sep-09-15 | | whiteshark: It is like the board is a desperate gambler at the end of their run... |
|
Sep-09-15
 | | Penguincw: That moment when all the pieces are still on the board. Anyway, I got 12...Bxh2+, and all the lines, except for 13.Kh1. I would've followed up with 13...Nf2+, but that's a hanging piece (but still might be winning). |
|
| Sep-09-15 | | houtenton: Dear chess-friends, do you still really like these kind of problems? May I suggest an other division, without any arrogance of course. One easy problem on monday will do. And then the rest of the week those "difficult" problems, giving us the desired chess-brainteasers and discussions. |
|
| Sep-09-15 | | kevin86: The bishop sacrifice leads to a quick mate...whether white takes or not. |
|
| Sep-09-15 | | BOSTER: < PB: just play 12..Bxh2+ <without thinking>. May be this is why white played 12.f3 < without thinking> instead at least 12.f4 or 12.Nx e4. |
|
| Sep-09-15 | | Once: <houtenton> "without arrogance" is easier said than done! I must admit that I do like the current system. Even a Monday puzzle can be hard if you don't see it. Today's puzzle still needs a bit of calculation to chase the White king to his doom. CG.com has to be broad church to appeal to players of all levels of ability. So I wouldn't want to ramp up the difficulty level too fast in the week. For me, it's just about right. And even when we have sucked a problem dry there is always the question of where the loser went wrong. The moves before a puzzle can be just as juicy as the puzzle itself. |
|
| Sep-09-15 | | houtenton: <once> OK, thank you for your answer, I wrote the post impulsive on my disappointment to see another Bxh2 or Bxh7 very obvious breakin. Often the first thought when you see a position like this one. But I can agree with you that there are much creative and interesting ways to go in all the different details of the concerning game, like f.i. <patzer2> does most of the time. Meanwhile I wait for another Shamkovich-Visier Segovia (move 48) beauty. |
|
| Sep-09-15 | | Chess Dad: I got the first move because the Classic Bishop Sacrifice is, well, classic. But I was expecting Kxh2 and didn't consider the Kh1 response. |
|
| Sep-09-15 | | The Kings Domain: Nice quickie (no pun intended). Considering the cramped positions, black was lucky to get a breakthrough with his attack on white's kingside. |
|
| Sep-09-15 | | Moonwalker: For the first time this week my first candidate move hits pay dirt rather quickly. Bxh2 was somewhat obvious given the crowded board. Even saw the under promotion for the final blow.
Bring on Thursday! :-) |
|
| Sep-09-15 | | starry2013: I eventually got this with the bishop sacrifice but for ages I was going with Qh4 which doesn't seem to work if played without that sacrifice. But somehow that looked like the first move. |
|
| Sep-09-15 | | tivrfoa: much easier than yesterday ... |
|
| Sep-10-15 | | Once: <houtenton> I suppose there are only so many chess tactics that can be shown. Even the most elaborate of combinations are made up of relatively simple elements - pins, forks, double checks, promotions, etc. |
|
| Sep-10-15 | | Coriolis: <Coriolis> <There is no mention of 13. ...g3+ on the comments page so it must be incorrect.> Fair enough, but is 13. ...g3+ not a sound move? |
