| Jul-07-14 | | zb2cr: This one is for all those who have ever complained that the <chessgames.com> Monday puzzle is always a Queen sac. This time, a Queen sac is a loser. The winning move is 30. Rg7, threatening Qxh7# next move. If Black plays 30. ... Bxg7, Qxg7#. Nay othe move is met by 31. Qxh7#. |

 | | skeptic50: Expecting the Monday morning Q-sac, then saw Rg7. Got it in about 15 seconds (my personal best). |

It's an interesting little puzzle. At first glance, the bishop on f8 seems to be doing a great job in holding back the white attack. Which is just as well, because the rest of the black army is hiding behind a wall of pawns. It turns out that the bishop is overworked. It has to prevent Qg7# and Rg7-Qxh7# The problem is that the poor cleric can only capture one piece landing on g7 - queen or rook. But it can't capture both. What black really needs is another dark squared bishop sitting on e9. As to what the tactic is called, might I humbly suggest that it is a form of reloader or substitution. White sticks one attacking piece on g7. When that is taken he replaces it with another attacker. It's a bit like starting a sword fight right handed and then later switching to southpaw ... or whatever the leftie version of swordfighting is called. |

 | | gawain: Very clever conclusion. 30 Rg7! is unanswerable. |

 | | Penguincw: I got the puzzle, but I don't think it's common for a Monday puzzle to have a quiet move (a move that doesn't capture a piece or give check). |
|
| Jul-07-14 | | dfcx: 30. Rg7 and mate next.
On move 27, Crafty found the following alternative,
27. Qxh7 Ke8 28. Rg8+ Bf8 29. Rxf8+ Kd7 30. Bb5+ Qd6 31. Qxf7# |
|
| Jul-07-14 | | sfm: <shaikh123: what's wrong with 30.Qg5?>
Nothing. 30.-,Bh6 31.QxB,Rg8 32.Rg7 (again!) and mate next move. |
|
| Jul-07-14 | | Castleinthesky: Slightly longer than the usual Monday morning, I'll give it a Tuesday. |

 | | kevin86: Gadzooks, I missed a Monday.
However, I cry foul! Queens are supposed to be sac-ed on Mondays- not rooks. AND NO coy, non forcing or non-checking moves either! |
|
| Jul-07-14 | | BOSTER: Strong Guy this guy, took Many. |
|
| Jul-07-14 | | jdc2: I would call the first move an interference, since it blocks the bishop from taking the queen. This creates the threat Qxh7#, forcing the bishop deflection to a square where it can be captured with mate. |
|
| Jul-07-14 | | PJs Studio: I can't say I've seen this exact motif before. |
|
| Jul-07-14 | | Chess Dad: When I see puzzle positions like this, where the winning player is down a bunch of material at the start of the puzzle, I wonder "When did he see it? Are we 5 steps into a big sacrifice combination?" And in this case, I think White saw the winning combination back on move 25 with the Nf6+ sacrifice, which was followed shortly thereafter with the 27. Rg8+ sacrifice. |

| Jul-07-14 | | M.Hassan: < SimonWebbsTiger: @<M.Hassan> try looking at 25. Nf6 Kf8 26. Qxh7 Qd8 and ideas like 27. Be2 and then g5-g6.> Looks like still Black holds:
25.Nf6+ Kf8
26.Qxh7 Qd8
27.<Be2> Bd6
28.Qh8+ Ke7
29.Qxg7 Qh8
30. What can g5-g6 do?
Am I missing something? |
|
| Jul-07-14 | | Squire49: Quite a challenge for Monday. Took about 1 Minute to spot Rg7. |
|
| Jul-07-14 | | kevinatcausa: <What would you classify this tactic, e.g. an attraction?> In 15th century Britain there was a Archbishop by the name of John Morton who was responsible for collecting taxes. His argument was that if you lived extravagantly, you obviously had the money to spare for your taxes. Conversely, if you lived modestly, you obviously were saving enough money to be able to spare some for taxes. In Bridge (the card game), people use the term Morton's Fork because of this to describe a situation where you present the opponents with a choice of plays, each of which leads to their demise in a different fashion. This is like the Morton's Fork of chess. |

| Jul-07-14 | | gars: <kevin86>, you are not alone. I missed it too! |

 | | Sneaky: Queen sac Monday! Easy peasy! Just play 30.Qxh7+ and ...Kxh7 is the only move, then I just grab my rook and slide it over to h3 for the mate. Wait a minute... where's my rook? I thought I should have two rooks. Oh dear, it's not a queen sac after all. Sheesh. What are they trying to to do us, make us think on a Monday? |
|
| Jul-07-14 | | PJs Studio: Hah! Good one Sneaky! |
|
| Jul-07-14 | | BOSTER: < Sneaky: I thought I should have two rooks >.
With two rooks you can win faster.
After 26.Qh6
if Bf8 27.gxf6+ 28.Kh8 Rg7
if Kh8 27.gxf6 Rg8 28.Qxh7+ Kxh7 29.Rh4#. |
|
| Jul-07-14 | | Cheapo by the Dozen: What could Black possibly have been thinking on 23 ... Bc5?? He removed a defender so as to force White to make an attacking move. Huh?? |
|
Jul-07-14
 | | PawnSac: the only candidate... Rg7 |
|
| Jul-07-14 | | thegoodanarchist: < Castleinthesky: Slightly longer than the usual Monday morning, I'll give it a Tuesday.> Right-oh! |
|
| Jul-07-14 | | sorokahdeen: This is funny. I never thought of Rg7! I just saw Qg5 which forces black to move the bishop to prevent mate on g8 allowing mate on g7. This does prolong the game by allowing a defense by ...Bh6 and ...Rb8, but *then* Rg7 wins again. It's amazing how little black had in the way of counter play. |
