| Jun-20-11 | | morfishine: What I find particularly useful on "Monday Puzzles" is to play through the entire game twice: once quickly, then once with more deliberation. This way, I can better understand how this position was arrived at. <Once> Again, your genius shines through. I happily refer all those interested to <Once>'s earlier post on this game in Feb 2010. I have a hard enough time producing one "witticism"; For <Once>, commentary and analogies seems second-nature and oh-so simple. Very enjoyable |

| Jun-20-11 | | k.khalil: Easy.
48...Qh3+
49. Bxh3 Rh2# |

| Jun-20-11 | | zb2cr: I remembered this from when it was used before, on February 15, 2010. |

| Jun-20-11 | | sevenseaman: To implement the recipes properly your wife has been nagging you
to get her more cooking oil measuring cans. You insist the two,
you bought her, 3 and 5 litre ones will do.
She is to take out exactly four litres of cooking oil from a large
economy drum.
Given that the two measures and the oil drum are the only utensils
to hand how will you do it smartly, with no wastages. Inter-transferring between the two cans, filling from, and emptying
back into the big barrel are to count as an operation each but only
until you get your 4 litres.
Anyone could do it in 9 or more ops. You did it in 8. And the wife
now says she could do it in 2 ops fewer i.e 6. Is she up to something or
just bluffing? |

| Jun-20-11 | | agb2002: Black has a knight for a bishop.
White doesn't seem to have any perpetual chances.
The rook on White's second rank and the knight cornering the king form a common mate pattern. Therefore, 48... Qh3+ 49.Bxh3 Rh2#. |

| Jun-20-11 | | AliTervia: SEVENSEAMAN MEASURING PUZZLE:
1) Fill the 5 liter can;
2) Empty the 5 ltr can in the 3 ltr can, leaving 2 ltr in the 5 ltr can; 3) empty the 3 ltr can back into the large container; 4) empty the 2 ltrs from the 5 ltr can into the 3 ltr can; 5) fill the 5 ltr can from the big container;
6) top up the 3 ltr can from the 5 ltr can, leaving 4 ltr in the 5 ltr can. Does that work? |

| Jun-20-11 | | stst: Q sac does it:
Qh3+ BxQ (forced)
Rh2# supported by N |

 | | scormus: <Once> Great commentary, and some nice play by B, I agree, W grabbing the g7 pawn was what I call "a snare and a delusion." |

| Jun-20-11 | | Once: <sevenseasman> Um, that's Die Hard 3? The one where Samuel L Jackson plays a character called Zeus. He and Bruised Willies are sent all round by New Yawk by yet another baddie played by an English actor? And en route they find themselves in Central Park where a five gallon drum and a three gallon drum are somehow connected to a bomb. As you do. |

| | scormus: Anyone ever noticed ... on Mondays there are usual at least 5 pages of posts covering a very simple puzzle. And a large chunk of that is interesting little side play and puzzles (often more interesting than POTD). At weekends you sometimes only get 2 pages and it mostly all about the puzzle position. <Once, Sevenseaman> wasnt the puzzle from a book by Sarah Flannery ?
But I cant figure that English baddie actor .... unless its Bicycle Chain. |

click for larger viewProblem: Black to move amd mate in 5.
Only one key move ... and one solution that I consider even close to being both correct AND aesthetic!!! (Solution tomorrow, engines will not help you find the correct line - they might find the first move, but after that you need logic AND chess artistry.) |

| | LIFE Master AJ: IF this problem is similar to anyone elses, I assure you its an accident. One thing I have always wanted to see ... a world-wide database for problems of all kind ... |
|
| Jun-20-11 | | estrick: For anyone who doesn't know that it's "queen sac Monday" this Arabian mate might be a bit challenging to find. More like a Tues level puzzle, I suppose. |
|
| Jun-20-11 | | PeterB: AliTervia, here is another solution:
1. Fill the 3, and empty it into the originally empty 5. 2. Fill the 3 again, and pour into the 5. This leaves 1 unit in the 3 can. 3. Empty the 5, and pour the 1 unit from the 3 can into the 5. 4. Fill the 3 can, and pour into the 5 can! QED. |
|
| Jun-20-11 | | WhiteRook48: 48...Qh3+ duh.
Note: 48...Ra1+ fails to 49 Rb1 and not the intended 49 Bf1?? Qh3# |
|
| Jun-20-11 | | sevenseaman: <PeterB> You have a <solution> but it does not beat <AliTervia>'s
because you have not counted each operation.
(Ops are f= fill, t= transfer can to can, e= empty into big drum) Yours.
<1. f 3
2. t into 5
3. f 3
4. t into 5
5. e 5
6. t 1 from 3
7. f 3
8. t into 5 in order to get 4lt>
<AliTervia>'s sol is optimal until someone does some magic. <1. f 5
2. t 3
3. e 3
4. t 2
5. f 5
6. t 1
to get 4 ltr.>
<scormus> Sideshows appear when puzzle activity ebbs to
a sepulchral low. I never heard of Sarah Flannery. This puzzle
appeared in the 'Reader's Digest' some 40 years ago. The solution
given was in 8 moves and attracted my attention because it struck
me as dilatory. The magazine accepted mine in 6.
<Once> I guess your recall of 'Die Hard 3' is associative to cans of 5, 3. Quite a few American movies came out in that genre. It was a fad that is yet to vanish. |
