Nov-22-10  estrick: <shishio71: The key to quite a few of these Mondays: When in doubt, sac the queen!>

Why be in doubt? Look for a queen sac first!

Nov-23-10  LIFE Master AJ: <<Nov-22-10 AylerKupp: <scormus> I used to be a software developer and the version of this saying that I like best is "There are 10 types of people in this world. Those that understand binary and those that don't." >>

01:37 AM

At first, I read this and I did not understand.

I thought about it for a little while ... and I laughed so hard that I fell out of my chair ... literally!!!

Nov-23-10  LIFE Master AJ: binary = ones and zero's or positives and negatives = on and off = oh, dangit! Nevermind!!!
Nov-23-10  LIFE Master AJ: <<Nov-22-10 Once: <dzechiel: ... I think you missed an opportunity to trot out the old "mating positions" chess joke.> Yes, but which one? The disappointed young man who bought a book entitled "200 French mating positions", only to find that it was about chess?

Or even ...

Q: ... "is this mating position legal?"

A: "No, it's Legall."

Or ...

Q: What do young knights hide under their beds?

A: Pawn magazines.

Or ... <once> a king, always a king, but <once> a knight is enough.

Or ... what kind of sex does Oedipus prefer? Mothered mates ....>>

Oh, crap ... now I am laughing so hard ... I might puke.

Jan-08-11  Lennonfan: Im new kibitzing on this site...(have i mentioned this once before?)....and i love analysing and guessing's daily puzzles,and seeing what the other kibitzers themselves have to contribute as most of you are so much more knowledgeable on chess than me,but the actual kibitzes by <LIFE Master AJ>are more entertaining for their amusement factor! Lol....quotes like"uh oh mr smarty pants!!" "i literally fell out of my chair laughing"(over a lame chess joke!!),"i laughed so hard i almost had an accident in my pants",and accusations of top top GM's cheating in games against him,amongst many other classics make me think that this man is either not for real....or not for real!! Keep up the humor life master AJ....this site needs you sir LOL
Nov-14-22  Brenin: 30 ... Qxg2+ 31 Rxg2 Rd1+ 32 Rg1 (32 Qe1 Rxe1+) 33 Bf3 mate. I love Mondays.

  takebackok: sack queen, no think Monday

Nov-14-22  mel gibson: Easy - a good beginners puzzle.
Nov-14-22  jrredfield: I found 30 ... Qxg2+ fairly quickly, although not immediately as I spent a bit of time looking at Qxg1 which fails quickly. However, after some analysis, I was amazed how many winning moves Black had at his disposal. In addition to the mate in 4 with Qxg2+, these also work, and perhaps others as well:

+11.96 30. ... Qf4 31.Qc3+ e5 32.Qg3 Be2 33.Qxf4 exf4 34.Re1 Rd1 35.Rxd1 Bxd1

+11.95 30. ... e5 31.Qc3 Qf4 32.Qg3 Be2 33.Qxf4 exf4 34.Re1 Rd1 35.Rxd1 Bxd1

+10.96 30. ... Bd1 31.Qc3+ Qd4 32.Qxd4+ Rxd4 33.b4 Bc2 34.e5 g5 35.b5 Rd1

+10.96 30. ... Rc2 31.Qe1 Qxe1 32.Rxe1 Rd2 33.Kg1 Rd1 34.Kf2 Rxe1 35.Kxe1 Kf6

+10.87 30. ... Rxb2 31.Qc3+ Kh6 32.b4 g5 33.Qc5 Qxc5 34.bxc5 Bg6 35.c6 Bxe4

+10.55 30. ... Rd3 31.Qc4 Be2 32.Qc2 h5 33.Qc1 h4 34.Qe1 Qxe1 35.Rxe1 Rd1

+10.18 30. ... Rd1 31.Qc3+ Qf6 32.Qc5 Qf1 33.Qc3+ Kh6 34.Qe3+ g5 35.Qxa7 Bf3

Nov-14-22  jrredfield: In other words, Black could have skipped his 30th move (a null move) and still easily win since White's king is so bottled up.
Nov-14-22  Cheapo by the Dozen: Sacrificing a heavy piece on the g-file -- one file off from the core Monday stereotype. :)
Nov-14-22  saturn2: Queen and rook assist but the bishop scores. Is this what they call a poacher's goal?

  al wazir: The solution was so familiar that I was sure this was a rerun of a recent PotD. But I see no posts from any date between 2011 and today.

I must be recalling another PotD that used the same idea.

  Breunor: It’s good to see we are getting Monday difficulty puzzles on Mondays again!

  agb2002: Black is one bishop up.

Black can weaken White's back rank and the light squares around the white king with 30... Qxg2+ 31.Rxg2 Rd1+ and mate in two.

Nov-14-22  landshark: Queen Sac Monday is in effect -
Nice to get one at a glance for once
Nov-14-22  boringplayer: <al wazir> There was something similar where Black sacs and drives the White King to a square where it and the White Queen get forked by a Black Knight. I was thinking I had seen it before, too.
Nov-14-22  Lambda: <In other words, Black could have skipped his 30th move (a null move) and still easily win since White's king is so bottled up.>

Being a piece up also helps.

In fact, black can even throw away the piece advantage by 30...Bf3? 31.Qc3+ and still end up with a winning rook and pawn ending.

Nov-14-22  TheaN: This looks familiar but I didn't post, from what I can see. <30....Qxg2+ 31.Rxg2 Rd1+ 32.Qe1 Rxe1+ 33.Rg1 Bf3#> is classic Monday though.
Nov-14-22  paavoh: Monday puzzle = faith in one's calculation abilities restored...

30... Qxg2+ 31.Rxg2 Rd1+ and mate with 32./33. - Bf3 follows.

  chrisowen: It's lanky its blind baroque Qxg2 abridge lag flick its abattoir blav its ago quotient Qxg2 eon;
Nov-14-22  Damenlaeuferbauer: After long pondering, the unknown (at least to me) Czech master Jan Schulz Sr. finally found the mate in 4 moves with the nice queen sacrifice 30.-,Qxg2!+ 31.Rxg2,Rd1+ 32.Qe1,Rxe1+ 33.Rg1,Bf3#. This game is an early example, how to play the Meran variation of the Semi-Slav with the black pieces.
Nov-14-22  Hercdon: Dilly dilly!
Nov-14-22  AlicesKnight: With a piece up, just capturing pawns will win the game, but ... Qxg2+ is more showy. After Rxg2, ...Rc1+ and the white Q can interpose to delay things by one move, after which Rg1 allows ... Bf3 finis.
