| Nov-15-16 | | dfcx: black threatens mate with Qb4, but it's white's turn. 44.Rxh7+ Rxh7
45.Qe5+ Kg8
46.Rg1+ Rg7
(Kf7 47.Qe6#)
47.Qxg7#
Black can delay the mate by one move with
45...Rf6
46.Qxf6+ Kg8
47.Rg1+ Rg7
48.Qxg7# |
|
| Nov-15-16 | | dfcx: Nice try, <Phony Benoni: First we look at the queen sac: 44.Qg8+!! Rgxg8 45.Rxh7#. Hoorah! Alas, it is not Monday.> It's not Monday and 44.Kxg8 foils he sac. |

 | | patzer2: For an early Black improvement, instead of 8...Qe7 =, I prefer 8...Nh5  as in J Arizmendi Martinez vs Grischuk, 2000.P.S.: For our Tuesday solution, I had no problem visualizing the mate-in-five with 44. Rxh7+  . |

 | | agb2002: White is one pawn down.
Black threatens Qb4#.
White can deliver mate with 44.Rxh7+ Rxh7 45.Qe5+: A) 45... Kg8 46.Rg1+ Kf7 (46... Rg7 47.Qxg7#) 47.Qe6#. B) 45... Rf6 46.Qxf6+ Kg8 47.Rg1+ Rg7 48.Qxg7#. |
|
| Nov-15-16 | | saturn2: I already had dismissed 44 Rxh7 but then I saw white can also check with the rook 46 Rg1+ which is decisive. |
|
| Nov-15-16 | | AlicesKnight: 44.RXh7+ Rxh7; 45.Qe5+ Kg8 (...Rf6 does not help); 46.Rg1+ and mate (Q on g7 or e6) to come....Let's see - exactly so. The king-hunt fails to catch its prey and suddenly Black is thrown back. |
|
| Nov-15-16 | | gofer: A nice <Easy> forced mate in five... 44 Rxh7+ Rxh7 45 Qe5+ Rf6 (Kg8 46 Rg1+ Kf7 (Rg7 Qxg7#) 47 Qe6#) 46 Qxf6+ Kg8 47 Rg1+ Rg7 48 Qxg7# |

White has a buildup of force against black's king (2R+Q), suggesting a sac to break the defense. Furthermore, black has his own mate threats (...Qb4#), indicating that whatever move we make should be check. So, starting with the obvious: <44.Rxh7+ Rxh7>

We still need to keep the black king in check, and exchanging rooks is the wrong way since white's attack with the lone queen will run out of steam allowing black to mate. The only other choice is <45.Qe5+>

Now it becomes clear that black is in big trouble. Moving the king out of check with <45...Kg8> exposes it to <46.Rg1+>

And now either
- 46...Kf7 47.Qe6# or
- 46...Rg7 47.Qxg7#. |

| Nov-15-16 | | mel gibson: Simple one today.
Mondays & Tuesdays seem to always involve a Rook or Queen sacrifice. |

 | | perfidious: One might say that Black was de Bauched in this finish. |
|
| Nov-15-16 | | stacase: All the moves were obvious. I kept thinking I'm missing something. But nope, it was that easy and that obvious. |

| Nov-15-16 | | clement41: This was chessvideos.tv's POTD a few days ago |
|
| Nov-15-16 | | morfishine: Another forced yawn |
|
| Nov-15-16 | | zb2cr: Got it rather easily. Nothing to add to good comments by <Phony Benoni>, <dfcx>, <agb2002>, <AlicesKnigh>, <gofer>, and particularly <YouRang>. |
|
| Nov-15-16 | | Cheapo by the Dozen: What <Phony Benoni> said. What happens if Black plays an immediate 41 ... Qa3? Does White have better than 42 Rg3+?
And does that even force a draw, or can Black win with 42 ... Kf7? |
|
| Nov-15-16 | | Pedro.Akcio: it's easy because we know we must give a check first in order to keep the pressure...thus Rxh7 is the only answer |

Kf7? > No, black loses. After 41 ..Qa3 42.Rg3+ Kf7 white has 43.Qxc7+ and now,, a) ..Ke8 44.Re3+ mates next move
b) ..Qe7 44.Qxe7+ Kxe7 45. Rxg2 wins a rook, but better is c) ..Qe7 44.Rxh7+ Kf6 45. Qxe7# (or Ke8 45.Qxe7#) d) ..Kf6 44.Qe5+ Kf7 45. Qe6#
and the rook exchange doesn't help...
41. ..Qa3 42.Rg3+ Rxg3 43.Qxg3+ Kf7 44.Qxc7+ Kf6 45.Qe5+ Kg6 46.Rg1+ Kh6 47.Qh2# and in this line there is also 44.Rxh7+ Ke8 45.Qe5+ Kd8 46.Qxc7+ Ke8 47.Qd7# |
|
| Nov-15-16 | | Dmitri27: Black did a mistake here on move 43 with Kh8. That was not a correct move. correct move was Rff7 with a draw as an eternal check appears on the board Qe8+ and Qe6+. But after 43... Kh8 a strong mating combination with the mate on 4-th move ends the game for black. |
|
| Nov-15-16 | | dark.horse: White wins by alternating Rook and Queen moves, digging the Black King out of the corner. |

 | | kevin86: In this game, white can check with one piece and pin with the other. |

 | | Gilmoy: I <remembered> having worked out a similar line once, so I tried that first, and it worked again. Homework done OTB once pays off twice! It's on my humble page, as a sideline to a mate: Gilmoy chessforum (kibitz #21), at the bottom. Here's the relevant position after a (hypothetical) <27..Kg8>:

| Nov-15-16 | | Bubo bubo: White faces the practically unstoppable mate Qb4#, so he has to seek his salvation in checks: 44.Rxh7+ Rxh7 45.Qe5+ with mate after A) 45...Rf6 46.Qxf6+ Kg8 47.Rg1+ Rg7 48.Qxg7# or B) 45...Kg8 46.Rg1+ Kf7/Rg7 47.Qe6#/Qxg7#. |
|
| Nov-16-16 | | stst: White is just one move to lose, as Qb4 shuts off its K - no escape square.
But it's White's turn, so it has to check in every step:
44.Rxh7+ Rxh7
45.Qe5+ .... (A) Rf6
46.Qxf6+ Kg8
47.Rg1+ Rg7
48.Qxg7#
OR, after 45.Qxf6+ (B) Kg8
46.Rg1+ Kf7 (if Rg7, 47.Qxg7# )
47.Qe6#
The Black K has not much free way to go either. |

 | | drollere: black threatens 44. ... Qb4#, so all white's moves must be either check or defense of b4. unfortunately 44. Qe1 fails to 44. ... Qxb3+, Kc5 (or lose the Q), Qb6#. fortunately, there is mate in 4:
44. Rxh7+ Rxh7
45. Qe5+ Kg8
46. Rg1+ Kf7
47. Qe6#
i agree this one seems easier than monday. |
