  Penguincw: For a second there I thought 27...Qxh2 wasn't mate. :|
Apr-14-14  Sihlous: He waited a move for a very simple reason...Because he could.
Apr-14-14  Memethecat: Thou bring thee knight into the fight; Jump to f3 now white can see; that gf3 it has no bite; the Qh2 extols her might.
Apr-14-14  Memethecat: Did Petursson not see 27...Qxh2#? ..doubtful.
Or was it head games cos white didn't resign like he should've..

  Oxspawn: Took me a couple of minutes to sort out the way forward as I examined a queen sacrifice on h2 or a rook sacrifice on g2. Then realised that once the g pawn is out of the way black can link f2 and h2.

26. ……Nxf3+
27. gxf3 (or Kh1) Qh2++

Apr-14-14  DrGridlock: Qxf3 is also forced mate (in 11).

  mjmorri: 21...Qxf4!!

  Sally Simpson: According to:

This was a round one game, not round 6.

Don't know if that had anything to do with the lad missing a mate in one. It happens, not going to slaughter the guy. I missed a mate in one mid-combo (allegro game) luckily, as here it did not matter. I've also played a move I thought was chekmate, but it was not, but again it only delayed the mate.


So all those who never played 27...Rxf1+ have infact failed this puzzle. You are 0/1 for the week.

And I will not tollerate any arguments on this matter. If you went for the mundane 27...Qxh2 mate it is not what was played. You are wrong. Get over it.


Two minutes browing on the net found the solution. I won't give the link, that would be pointless as I am sure not many of you speak icelandic.

On the board next to this game a player deep in time trouble wanted to under-promote to a Rook. (he already had both White Rooks on the board, this was to be his third.)

Petursson saw them frantically looking about for a White Rook so took on f1 and tossed the Rook to the arbiter.

  Once: <DrGridlock: Qxf3 is also forced mate (in 11).>

An excellent find! We do get our Monday queen sacrifice after all.

After 26...Qxf3

Black threatens Qxg2#. If 27. gxf3 Nxf3+ 28. Kh1 Rxh2#

click for larger view

Or 27. Rxf2 Qxf2+ 28. Kh1 Qxe1#

To extend the time taken to mate, Fritzie thrashes around by throwing his queen away with moves like Qa8, Qc6, Qe4 and Qg4.

A delicious alternative solution. I salute and thank you.

  maxi: I don't know what is the big deal, <Once>. I also can improve the line: 26...Nxf3+ 27.Kh1 RxR 28.RxR e2! and checkmates in a few moves.
Apr-14-14  BOSTER: <Doniez ...why to wait another move...>

This is not always
the truth, that a winner who was finishing
first, sometimes the winner who was
finishing second.

Apr-14-14  kevin86: This one has several answers: Qxf3 and Nxf3+ to name a few.After the knight check- mate will come next move at h2 by the queen.

Either the knight will support the queen or if said knight is captured, the rook's road to h2 is opened and mate will follow that way.

Apr-14-14  TheTamale: This was kind of hard for a Monday. I got it, but I never would have seen it OTB.

That being said, Black did the right thing. Grandmaster sees a spite check, gives a spite check.

Apr-14-14  BOSTER: < DrGridlock Qxf3 is also forced mate>, but this is not Monday solution after Qg4.
Apr-14-14  MostlyWatch: Those Lewis pieces trigger a thought. The pawns look like tombstones. There are people trying to figure how to rescue the game if it ever gets completely solved, like tick-tack-toe. Maybe the pawn could be changed... when captured, it becomes a tombstone which can't move or capture, but it blocks movement. I just throw this out with no analysis.

  perfidious: This took, like, three-billionths of a nanosecond.


Back on the (relatively) serious side of things, a much sharper way to play this--though I have no idea how Dame Theory views it nowadays--is 5.f4.

Apr-14-14  PJs Studio: I like Qxf3. More fun.
Premium Chessgames Member
  Domdaniel: Three billionths of a nanosecond, like <perf>. They don't really get any easier than this.

Without meaning to sound condescending or superior, I'm interested in those who found this difficult. Is it some general tactical difficulty, or some unique feature of this position?

The Nf3/Qh2 mating pattern may be a routine one, but even Kramnik missed it against Deep Fritz.

Apr-14-14  Whitehat1963: Took me a lot longer than it should have. That's a good Monday puzzle. It's a simple, forced solution, but it's not the same old queen sacrifice.
Apr-14-14  Patriot: It is kind of strange why black played 27...Rxf1+.
Apr-14-14  Halldor: Sadly Margeir Pétursson quit professional chess several years ago. He founded his own bank, MP banki, in 1999 "with $1 million investment cobbled together from several people" (according to NY Times 2009/07/04). The bank has been very successful also in the bank crisis 2008 when it started to swallow other banks and has been spreading out in Europe. MP has been living in Ukraine the last years (MP banki bought the commercial Bank Lviv in western Ukraine in 2006), but in an Icelandic newspaper review some months ago MP said that the situation in Ukraine had become more and more difficult for foreign investors. ( ; see there 'History').
Apr-15-14  Zuainedison: What´s most stetic? queen sacrifice (...Qxf3) or speed mate (...Nxf3+)?
Apr-15-14  PJs Studio: Usually here we have; puns (mostly good); arguments and insults (also of decent quality); analysis (of excellent quality) or references to other games/position (which I adore...)

This conversation however, has gotten ridiculous. Yes a computer would play Nxf3 and so would most of us. But why Petursson didn't is moot and pointless


Apr-20-14  LIFE Master AJ: May I ask a question?

Is there some sort of story behind this game? Why did Black play 27...RxR/f1+? Why not the immediate mate on h2?

Apr-23-14  PJs Studio: Ok... Time trouble. 0-1
