Jan-21-19  zb2cr: 44. Qb8+ does it. I took a while to see that if 44. ... Ke7; 45.Qf8#. It's easy to see that if 44. ... Rc8; 45. Rxd7+ with a discovered attack on the Black Queen will cause White end up with Queen for Rook.

  ChessHigherCat: 44. Qb8+ Rc8 (...Ke7 45. Qf8#) 45. Rxd7+ Kxd7 46. Qxe5

Took me longer to get than some Wednesdays.

Jan-21-19  Walter Glattke: Recycled Oct 16-18
Jan-21-19  drollere: 44. Qb8+ Rc8 [otherwise Qf8#] 45. Rxd7+ wins the Q and mate to follow.
Jan-21-19  saturn2: I remember it.

  Willber G: <agb2002: Recycled.>

Previously on a Tuesday which I think was more appropriate.

Jan-21-19  cocker: We're not getting very good value any more.
Jan-21-19  houtenton: <cocker> I really agree with your remark! Bxe5 is a very strong move; if you are able to see this, you are at least a very good chessplayer (in my opinion).
Jan-21-19  houtenton: <cocker> I ment your first remark with the analysis of Bxe5.
Jan-21-19  TheaN: Hah. It actually took me a while to realize that I did see the intriguing mate on f8 were Black to step aside; then I noticed I solved this before, as after Rc8, Rxd7+ decides. Bit odd to recycle a Tuesday as Monday about three months later.

  whiteshark: 44.♕b8+ ♔e7 45.♕f8# or 44...♖c8 45.♖xd7+ ♔xd7 46.♕x♕e5 as <Walter Glattke> mentioned rightly first of all.
Jan-21-19  DDAYII: Lordy be
Jan-21-19  Cheapo by the Dozen: I found this to be Tuesday hard -- which makes sense :) -- and did NOT remember it from before. (Actually, I see that people previously complained it was hard even for a Tuesday.)

The reason I didn't find it harder yet is that I determined White really needs to keep checking, because Black is up a piece and, more important, has a bunch of open lines to White's king. The reason I didn't find it easier yet is that that determination was not 100% rock solid. :)

This one took me much longer than a typical Monday puzzle. It is definitely "Tuesday-strength", if not "Wednesday". The key idea (exploiting Black's undefended queen by preparing a discovered attack along a backward diagonal line, b8 to e5) is a much deeper concept than the theme of a typical Monday puzzle.

One move later (if Black had actually played 44. ... Rc8) the position would have made a suitable Monday puzzle.

  dorsnikov: I guess I'm doomed to being a patzer. I went with RxB and come what may?

Wasn't that "Very Easy."

Jan-21-19  sfm: <dorsnikov: I guess I'm doomed to being a patzer. I went with RxB and come what may?> Well, it loses quickly, but the _idea_ is actually non-patzeristic (which is proven by the fact that it was the first move I looked at :-) And RxB+ is indeed the solution - we just have to rearrange a little first.
Jan-21-19  drollere: <We're not getting very good value any more.>

i believe this is the second puzzle that i have seen identified as a "recycle". as if, for example, there is an impediment to the selection of new puzzles or old puzzles of great vintage.

i did the experiment of choosing a reputable player name as white in the search function ("Fischer"), set the number of moves to "<=" 25, and discovered over 120 games.

the limit on the game moves represents the idea that a professional game of chess does not end in <= 25 moves unless it contains some clever play on one side or another; setting aside the draws that in tournament play represent something procedural.

i was then able, simply by clicking on a move in the game record that was two or three or moves before the opponent resigned, to find a position not far from the coup de grāce, and put to myself the next best move.

in other words, a home baked puzzle.

gosh, though ... i had to do it myself.

and, heck ... i couldn't complain (as the most interesting comment i could muster to the community) that "it isn't a Monday puzzle" or "this should be a Wednesday puzzle."

i couldn't even proclaim "hey! i'm 1 for 1 for the week!" or even "i could solve this!"

it's when i read comments like that that i remember the directive on the home page to "learn from players stronger than yourself, while guiding those who are weaker."

and i ask myself: should i learn from players stronger than myself to day-rank puzzles as too easy or too hard for the weekpart?

or should i guide those who are weaker than myself to day-rank puzzles as the best way to improve their game?

ah, the difficult decisions we face in life.

i will say that there are the boasters, then there are the day-rankers, and at the top of the heap are the whiners.

the whiners display a mentality that is approximately "what have you done for *me* lately?"

the *few* members who actually contribute meaningful analyses ... well, they soldier on without credit.

they are the suckers.

they should get with the program:

"Chess dot com! the premier venue on the web where chessplayers of all strengths can meet to complain about the day-rank of chess puzzles."

Jan-21-19  houtenton: <drollere> I hope I'm understanding your comment. It is very difficult (to get the point). Let's rank your comment as a saterday comment. I can agree when you ment that there is an endless discussion about the day the POD should belong to or fits best, I think that it is very personal; what is easy for you, can be difficult for another. I spent once a whole day in trying to solve a POD without succes and afterwards it seemed to be easy for everybody. Better to change the rank-system. I miss a bit the extended analysis we had in the past, like those from patser-2 f.i. Let's play chess, indeed.
Jan-21-19  King Harvest: @<drollere>....

Easy now, <Cocker>'s a premier member, so he's supporting the site. He's allowed to whinge a bit about the value of a puzzle that's recycled from three months ago. That probably is an oversight on CG's part. But the real value of the CG POTD for me has always been in the kibitzes not the puzzles.

I knew right away this one would bring out the "not a Monday" comments... evaluating the puzzle strength/day of week correlation is harmless and a waste of time... but then that's what most folks think of chess... so let's indulge...

The solution line is two moves deep, it's a check, and it has two variations... that's objectively a Monday IMHO. Subjectively it definitely feels a bit harder than what we've gotten used to on Monday... as one variation wins material rather than forcing mate, and neither second move is particularly easy to see. I looked at Qb8+ early, didn't see how quick and forcing it was, and had to cycle back around to it after rejecting other candidates.

I hadn't seen this position before and enjoyed it.

Jan-21-19  King Harvest: Hmmm --my analysis flawed (no surprises there) about it being a two-move solution. I somehow lost a ply in my gentle musings on the mondayness of it.

Is that the ply in the ointment?

Jan-21-19  King Harvest: Also, what the heck kind of name is <La Rota!?> Isn't that Spanish for "the broken"?
Jan-21-19  Monocle: Took me a while to realise that 1.Qb8+ Rc8 2.Rxd7 was a discovery on the queen. Visualising a line being open several moves into a calculation is one of the hardest things in chess for me.

  OhioChessFan: <Monocle> I have absolutely zero ability to visualize. I can't believe people say it's easy to play blindfold.

  Dionysius1: Great!

Quite pretty, and a pattern I hadn't seen before so I had to work quite hard. Very satisfying to get it.

And it wasn't one of those "Monday Queen sacrifices" which did get tedious. Even I suspect to beginners, who wouldn't need more that 2 or 3 ♕xh7, ♖h3 and mate type puzzles to get the idea and want to see something fresher.

I am one satisfied customer.

  ChessHigherCat: I think there's some objective rationale for easy Monday problems and progressively more difficult ones, namely:

- a Monday puzzle should be solvable by beginners to encourage them to continue; if no beginner could possibly get the puzzle so that it makes them all feel like shyte-on-a-stick, it's not a good choice;

- the same logic applies to the other weekday puzzles but for progressively higher ratings;

- a Sunday puzzle should draw our attention to the legendary players so that we can admire their amazing tactics and set a distant objective to strive for; if we can ever solve them, we can congratulate ourselves.
