Oct-28-08  MenisfromVenis: Easier than yesterday's puzzle.
Qxf2, followed by mate with the Bish.

Oct-28-08  Patriot: Easy, easy, easy...But how many of us would see the queen sac OTB with 5 minutes on the clock? In a real game there is no one holding up a sign that says "Black to play and win!"

In this puzzle, I didn't even bother looking at material differences because it looks like white is in a mating net. Unless black is in check, who cares if white has an extra piece somewhere if black can force mate? I first looked at 20...Nf3+ and quickly dismissed it because black has destroyed any chances of mate or regaining the lost material. So then I turned to 20...Qxf2+ 21.Kxf2 (21.Kh1 Qg2#) and then I saw 21...Be3#. Then I double-checked the position to make sure it was really mate.

  gawain: Maybe easy but it is a fantastic mate with the criss-crossing bishops. This is one of the prettiest I have ever seen.

On the emrald chess site, Q+B mate with criss-crossing diagonals occurs frequently enough that I would now call it a common mate. The analogies to Boden's mate (referred to below) help fix it in one's head.

  johnlspouge: In addition to noting how many legal moves the K has, it is worth noting whether the K provides protection, to facilitate seeing decoy combinations like today's.
Oct-28-08  The Rocket: "Easy, easy, easy...But how many of us would see the queen sac OTB with 5 minutes on the clock?"

I would see it with 5 sec on the clock

Oct-28-08  Patriot: <The Rocket> "I would see it with 5 sec on the clock"

That is great! My main point was that it's a lot different looking at a puzzle knowing there is a win, and seeing the same position OTB with the clock ticking. I think I would see it but not in 5 seconds.

True, in an OTB game there is nobody suggesting to you that a winning tactic is at hand. That's the advantage of a puzzle.

On the other hand, the advantage of an OTB situation is that you arrived at this position with a much better understanding of its dynamics that you would if just presented with a position out of the blue.

In this game, I doubt that black just 'stumbled' onto this position. I think that for several moves (at least ever since he placed his bishop on h3 on move 16) he had been looking for ways to exploit the semi-open f-file, and he saw e3 as an excellent attack point for his DSB.

So when the opportunity arose with 20.Be2?, he probably jumped on 20...Qxf2+ with hardly any thought other than "whoopee!".

  kevin86: Strange:yesterday we had a mate in three,today a mate in two-whether white captures the queen or not!

A brilliant crossfire mate.

Oct-28-08  BishopofBlunder: This reminds me of some of my games (with me playing white, of course).

20.Be2 was a horrible mistake. I have been looking at 20.Bg2 for white instead. While still leaving white in a bad position, it seems to stave off the immediate mate threat. Does anyone else see anything that I don't?

Oct-28-08  BishopofBlunder: <kevin86: Strange:yesterday we had a mate in three,today a mate in two-whether white captures the queen or not!>

If this trend continues, I look forward to Wednesday's puzzle. A mate-in-one even I can't miss!

Oct-28-08  ruzon: <ewart cooper: y not bf3 g2
BishopofBlunder: I have been looking at 20.Bg2 for white instead.>

I think 17.Bg2 would be a whole lot better for White. Taking the rook off the open f-file weakened White's position considerably.

  gawain: <johnlspouge> points out that this mate falls into a fairly common category. True, but this one is unusual in one respect. The mated K is on the SECOND rank. He has an unusually large number of potential escape squares to be covered. So here the bishops are helped by the knight (covering f3) and the d-pawn protecting the bishop on e3. And white pieces occupy the other three escape squares.

I think the advanced position of the K is what struck me about this position. Tha mating net is very efficient.

Oct-28-08  Chris1Clark: 20. Be2 is the most horrible blunder by white.
Oct-28-08  Patriot: <YouRang: On the other hand, the advantage of an OTB situation is that you arrived at this position with a much better understanding of its dynamics that you would if just presented with a position out of the blue.>

Very true. It also depends on the player's strength. For example, if you are rated around 1000 USCF it's not likely you will see this OTB because it involves "sac'ing the queen". But I can also see a 1400 or 1500 player missing this in an actual game. I've even seen experts miss easier tactics where they had plenty of time on the clock.

  Once: My first thought was to play 20...Be3 21. Pass Qxf2+ 22. Kh1 Qg2# (or Bg2#).

Okay, so passing is not legal (and certainly not white's best defence). So can we take those elements and recombine them into a sequence that does work?

20...Be3 goes nowhere, so let's try 20...Qxf2+. Now it does not take long to spot that both 21. Kh1 and 21. Kxf2 allow mate in 1.

Nice one.

Now, let's try to defend for white instead of the lemon 20. Be2? Let's try 20. Bg2 Bg4 21. Qb1 Nf3+ 22. Bxf3 Qxf3 23. Qd1 Qxd1 24. Rad1 Bxd1 25. Rxd1 Rxb2

White isn't mated, but is the exchange down and has a grim position to defend.

  patzer2: For today's Tuesday puzzle solution, Black plays 20...Qxf2+! to initiate a mate-in-two.
Oct-28-08  VooDooMoves: What's the name of a mate with two bishops? I have always called it a scissor mate.
Oct-28-08  Nullifidian: <VooDooMoves: What's the name of a mate with two bishops? I have always called it a scissor mate.>

The name for it is Boden's Mate. This game is not a true Boden's mate because the knight is cutting off the king's escape to f3.

However, there are several true Boden's Mates in the database, including the original Boden's Mate. They're collected here: Game Collection: Boden's Mate. Boden's Mate can often involve queen sacs. I just recently won a local chess club tourney game by recognizing the almost exact same pattern as Alekhine vs Vasic, 1931 in a game opening with the French Winawer.

Oct-28-08  zooter: yippe...

20...Qxf2+ 21.Kxf2 Be3#

I did not see that white king can decline the queen sac and escape to h1 to be mated, maybe i've y ibecome a little rusty...for thoe who're wondering why im missing, it's coz of my marriage... :) (still busy with it, but couldn't resist jumping onto this site)

btw, I agree way too easy for Wednesday, more likely a Tuesday

Oct-29-08  KFitzgerald: I tried a couple of different combinations starting with ♗e3 and ♘f3+ but they kept getting complicated.

So I thought let's look at the ♕ sac. And it was surprising how easy that was. Made me wonder why I did not try that first.

<Nullifidian thanks so much for linking to the collection of Boden's Mates>
