Feb-27-17  dfcx: Dovetail mate!
Feb-27-17  Cheapo by the Dozen: What is the point of White's opening, other than a generic desire to avoid book lines?
Feb-27-17  stst: 53......Qxa2+
54.KxN Qa5#

Besides, the following also fun:

The fP is a great asset, so 53.........f2
WQ can only guard the promotion by
54.Qh3 Nc2+
55.Kb2 (if 55.Ka4 Qa5#) Ne3 dis+
56.Ka3 f1=Q, guarded by N.
(( 57.QxQ(f1) NxQ ))

  An Englishman: Good Evening: <Cheapo by the Dozen>, the point of 4.Qxd4 consists of establishing a bind with c2-c4 after 4...Nc6; 5.Bb5,Bd7; 6.Bxc6,Bxc6; 7.c4 and White's space advantage compensates for the loss of the Two Bishops. 4...a6!? guarantees that the Queen must flee, but White won't mind after 5.c4,Nc6; 6.Qe3. If White likes the c4 & e4 vs. d6 and e7 pawn formation, this opening is a great choice.

Which explains why 5.Bg5 is a mistake. From moves 6-9 Black makes all of the threats in a variation known to be good for the second player. 5.Bg5 is by no means a losing move, but it does not conform to White's needs or goals in the Qxd4 lines.

Feb-27-17  Doniez: Again, like last week. Mating notation is missing Qa5#.
Feb-27-17  agb2002: Black has a knight and a pawn for a bishop.

White threatens Qxf6.

Black can deliver mate in two with 53... Qxa2+ 54.Kxb4 Qa5#.

Feb-27-17  saturn2: ..Qxa2 sacrifices the knught for a pawn and mate.
Feb-27-17  YouRang: Yes, <53...Qxa2+> and mate next was quite easy.

Looking for a more interesting variant, I tried <53...Nd3>,

This also threatens mate (54...Qb2+ 55.Ka4 Qxa2#), but it gives white a chance to squirm.

The squirming doesn't last long, but black needs to be accurate: <54.Bg8+ Kg7!> (54...Kxg8 is not good since 55.Qg4+ forces black to play 55...Qg5 to avoid a draw) <55.Qg4+ Kh8!>

The black king uses the white bishop as a shield. Black can't give any meaningful checks, and cannot stop the ...Qb2+ mating threat.

Feb-27-17  stacase: Took about two seconds to see that one.
Feb-27-17  AlicesKnight: 53....Qxa2+ forces 54.Kxb4, when ...Qa5# has the White K in a cleft stick. But it was all over long before ...
Feb-27-17  The Kings Domain: Nice game. Somewhat confused and all over the place, typical of a ladies' game. :-)
Feb-27-17  cocker: The puzzle could have started on any of moves 50, 51, 52.
Feb-27-17  whiteshark: I felt a bit sheepish about reporting
<The last move should indicate mate (#)>
Feb-27-17  HowDoesTheHorsieMove: <Took about two seconds to see that one.>

This was very easy, even for a Monday. Still, I spent more than two seconds just to see whose move it was.

Feb-27-17  morfishine: The ole one-two: <53...Qxa2+> followed by <54...Qa5#>

<YouRang> For goofs, I also looked at 53...Nd3, but with the immediate threat 54...Qa5# (since the Knight now covers <b2>)

*****

Feb-27-17  Walter Glattke: In the YouRang diagram 2 follows 56.Qg7+ otherwise 56.-Qb4# or 56.-Qa5#, Qb2+ must be played after 55.Qe1 only.
Feb-27-17  DrGridlock: The White King's journey in this game is to be studied:

K-e2-f1-g2-f1-e1-d1-d2-c3-b4-a3-b2-a3-b4-mate

Kids, don't try this at home!

  gawain: This one sent me to the reference books to see what the mating pattern is called. Seems to be a variety of Dovetail. (Or Cozio? Are these the same thing?) This is quite a nice example.

Such a long and winding road is taken by the poor White king!

Feb-27-17  Marmot PFL: much simpler than last week
Feb-27-17  kevin86: White gets chased around the corner to his doom!
Feb-27-17  YouRang: <morfishine><Walter Glattke> Yep, in my variant line, I was so focused on giving check at b2 that I overlooked the one-move-quicker mates at b4 or a5.

But then again, if I were so concerned about minimizing moves, I'd just go for 53...Qxa2+ ;-)

First time I've seen that game - nicely done.

  mjmorri: It seems like every time White offered a piece trade, Black's position improved.
Feb-27-17  BOSTER: 23.c5 was very attractive.
If Bxc5 24.Bxe5.
