  patzer2: White's decisive error was 19. Qc1?? Instead 19. Qh5! avoids the 19. Qc1?? Qxd4! tactical shot and steals back the initiative and the advantage.

According to Fritz 12, Black's missed opportunity was 17....Ba4! which maintains a strong extra pawn advantage after 18. Qe2! Qxd4 19. Bg2 Qxf2+! 20. Qxf2+ Nxf2 21. Kxf2 Rd8 to (-1.82 @ 21 depth).

Apr-24-14  Nick46: Qsac on a Thursday, well I'll be a blue-nosed gopher.
Apr-24-14  devere: <paavoh: I thought this was a bit too easy for a Thu puzzle.>

You are right, it belongs on Tuesday.

  kevin86: First, I nixed the sacrifice of the queen because the king could escape to f1. But then the bishop checks and the king can escape no more.
Apr-24-14  sombreronegro: Was an easy Thursday. The pinned pawn making the f3 square weak jumps out at you, especially with the back knight eying it with check. Then you see the white knight on d4 is covering the square.
Apr-24-14  griga262: This was easier than yesterday, and I am not good with Thursdays usually. I agree with the others, it belongs on Tuesday.
Apr-24-14  sombreronegro: whiteshark: <Unusual. Eliminating one defender makes two unrelated checks possible. And lethal.>

Well that's just the thing about knights. Their defensive duties can only be directly reinforced by another knight. Its holding up f3 and b5. The queen took it right for a glue horse.

  Domdaniel: It *must* be easier than usual, as I saw the win in a couple of seconds. But I like <Once>'s version of the game -- though I'm intrigued by his 'priapic' Fritz ... is that a special feature?
Apr-24-14  gars: Congratulations, <chrisowen>!! You have outdone yourself today!

  Once: <Domdaniel> When I switched off the annoying speech (there are only so many times that you can hear the "joke" about the horse walking into a bar), I started to imagine what other voices Fritzie might use.

In some versions of this flight of fancy he is Agent Smith from the Matrix ... "As you can see, Mr Once, we've had our eye on your for some time ... one of these variations has a future. One of them does not."

Every now and again I hear him as one of the stars of the Carry on Films - either Sid James "phwoar" or Kenneth Williams "Ooh, Matron!".

Sometimes he is Victor Meldrew ... "I don't believe it."

Then again he can be 300's Leonidas ... "This is the Sicilian!"

Just occasionally he slips into bedroom mode as pure Barry White' hence the homage to Priapus.

I haven't yet found the imaginary button which will turn him into chrisowen/ Stanley Unwin.

  Domdaniel: <Once> Heh. A <chrisowen> button? That, I suspect, is still beyond the reach of Fritzie's programmers.
Apr-24-14  Patriot: Material is even.

19...Qxd4 20.Bxd4 Nf3+ 21.Kf1 Bb5+ 22.Qc4 Bxc4#

20.f4 Qxe4 21.Qd2 Nf3+

I don't see a challenging move for white.

Apr-24-14  BOSTER: <Once> There is one point of your narrative why you can not get the brilliance prize. You missed the pearl!

This is the pos. white to play 11.


click for larger view

In the Napoleon's era (or Anderssen) ,when material counted for little and every player looked for attacking pos. and combinative possibilities.

Game should continue like this (sacr. two rooks!)

11.Qd2 Qxa1+ (if Qxc4 Rc1!) 12.Ke2 Qxh1
13.Nxe6
if Nd7 (or Bd7) 14.Nc7+ Kf8 15.Qd6+ Kg8 16.Bxf7+ Kxf7 17.Qd7+ Kg6 18.Qxg7+ Kh5 19.Qg5#

if Nc6 you can find cont. himself.

  gawain: Yes!!! The only thing stopping ...Nf3 fromd4 being checkmate is the white knight on d4. So take it 19 Qxd4 and see what happens. It's nice that the bishop is available to deliver the mate in case White captures the queen.

All in all a nifty finish

Apr-24-14  Patriot: It seems that 20.f4 is the only move that really makes an attempt to counter black (since the direct 20.Bxd4 doesn't work). Anything else, and white is down a piece for nothing! 20...Qxe4 is a killer, threatening mate which gives black time to retreat the knight if needed.

White would need some sort of double-threat or check to get out of this.

Apr-24-14  Herma48852: Saw this immediately .. sac the Black queen to get rid of White knight on d4 produces an unstoppable.

16. .. Qxd4
17. Bxd4 Nf3+
18. Kf1 Bb5+
19. Qc4 Bxc4#

If White declines the sac, he is down a whole piece.

Apr-24-14  bachbeet: Don't usually get these puzzles that are later in the week but I got this one.
Apr-24-14  TheBish: M Subaric vs P Trifunovic, 1946

Black to play (19...?) "Medium", even material.

I think this is fairly easy. I got it right away because naturally I was looking at the obvious ...Nf3+, but of course the knight on d4 prevents this. So the next logical step is to remove the knight, but there is only one way to achieve this, the queen sacrifice. Once you look that far, the rest falls into place.

19...Qxd4!! 20. Bxd4

If White declines the "generous" offer, he is just a piece down and will lose slowly, so resignation is more likely.

20...Nf3+ 21. Kf1 Bb5+ 22. Qc4 Bxc4#.

  Once: <BOSTER> In chess it's generally not a good idea to play sub-optimal moves hoping that your opponent will fall into a trap. This might work against beginners but will cause no end of pain when you start to meet more experienced players. It's what Dan Heisman calls "hope chess".

Here's the position after 10...Qxc3+


click for larger view

White has two sensible ways to get out of check - 11. Kf1 (as played) and 11. Qd2 (your suggestion).

After 11. Qd2, black would lose if he grabbed both rooks with a position not dissimilar to the immortal game. 11...Qxa1+ 12. Ke2 Qxh1 13. Nxe6. White has all the attack and black is a bystander.

But black doesn't have to grab the rooks. Instead he could (and should) play 11...Qxd2+ 12. Kxd2 gxf6 leading to this position


click for larger view

Fritzie calls this as broadly level as opposed to the small edge to white of 11. Kf1. White is temporarily better developed but his king is exposed and his advanced knight and bishop could get kicked back or pinned by a later Rd8.

All in all, the plan of 11. Qd2 Qxa1 only wins for white if black plays a poor move. With best play it leads to little more than equality and a slightly worse position than the move that was played.

In other words, this line only happens if both white and black play second best moves. 11. Qd2 isn't white's best way to meet 10...Qxc3+ and 11...Qxa1 isn't black's best way of replying to it.

One day, Boster, one day. But not yet and not today.

Dec-17-17  TheBish: <Once, BOSTER> There is actually a game here that features that very double rook sac. The infamous "NN" took the bait, in a correspondence game, no less! He was quickly punished.
