|Sep-14-09|| ||Patriot: In my previous post for example, 10...Qxe5 11.Nxa8 Nc6 12.Nd5 and the knight is ready to be extracted.|
Or if 10...Qxc4 11.Nxa8 Nc6 12.Rd1+, the black king cannot approach and snag the knight: 12...Kc8 13.Bxa7 Qa6 14.Nb6+ Kc7 15.Rd7#.
|Sep-14-09|| ||YouRang: I got it almost instantly. :-)
Once you've been on the wrong side of that combination, you never forget it. :-\
|Sep-14-09|| ||kevin86: White king to white queen:I have to take this.
Black queen to white king:I have to take this,pointing at white's queen.
Sounds like a classic opera plot.
|Sep-14-09|| ||playground player: Is this an official and bona fide Albin Countergambit Wipeout?|
|Sep-14-09|| ||BOSTER: 6...Bxf2-deflection and after 7.Kxf2 white queen is lost.
If so young bishop from enemy army can lure the white king, what can I say about white kingdom.
Once in correspondence game after moves
6.g3 Nxf2 and white resign because after 7.Kxf2 Bxg3.
White lost the queen.
"You should think-maybe a few days more! about queen's security" noticed E.Gik.
|Sep-14-09|| ||zanshin: Well, this one wasn't too hard - but it's only Monday ;-)|
<stanleys: Perhaps NN could have played 6.Nxe6?!>
Quick Rybka analysis shows the top 3 moves for White were 6.e3, Be3 and Nxe6:

|Sep-14-09|| ||WarmasterKron: Easy, first thing I looked at.
<TheaN> 5.e3 leads to standard Albin positions, but after <5.Nxd4 Bc5>, 6.e3 does not. With the Black pawn gone, there's obviously no dxe3/exf2 threat.

There's no way of being completely certain, even for the best. I've seen GM's make these errors. But all you can do is minimize their occurence through practice of basic tactics and learning a good thought process.
|Sep-14-09|| ||DeltaHawk: this is similar to the game Ingrid Oen Carlsen played against Alf Goran Jakobsen in Arctic Chess Challenge 2007. She resigns after her opponent's bishop attacks her king.|
|Sep-14-09|| ||Once: I'm going to try something a little different with these puzzles. Instead of focussing on the puzzle solution (which others do far better than me), I'm going to look at how we got to the puzzle position. The idea is to try and pinpoint the positional and tactical motifs that made the finish possible. Hopefully, this will help us to get these positions in our games - and to spot the tactics when there is no-one there to point out that a tactic is possible.|
Over time, this ought to build up to a sort of library of mini articles about common patterns. A sort of DIY guide to puzzles. As with a lot of things I try, it might be rubbish or it might be interesting. But let's have a go and see how it works out. I'll copy the posts to my home page to keep a reocrd (and in case anyone wants to add other thoughts or examples).
We will start off with ...
|Sep-14-09|| ||Once: Today's theme is about the removal of the defender. White leaves the two queens staring at each other along an open d file. But the only thing defending the white queen is the king sitting on its home square. If black can deflect the opposing king, the queen would be lost.|
Here's the unplugged position ...

Bxf2+ deflects the white king, allowing black to play Qxd1.
The trigger for this sort of position is when heavy pieces are attacking each other, but one side is relying on another piece for defence. In situations like that we should be looking for ways to kick the defender away.
|Sep-14-09|| ||YouRang: <Once> Since I'm in the mood to be a nit-picking jerk, I'll point out that in your last diagram, ...Bb4+ is actually better (we win the queen AND keep our bishop). |
We'll need that bishop to deliver checkmate, seeing that we lack a king for that purpose. ;-)
|Sep-14-09|| ||minasina: < YouRang > :)|
|Sep-14-09|| ||cracknik: There was a puzzle where white wins th queen in this fashion not too long ago.|
|Sep-14-09|| ||WhiteRook48: 6...Bxf2+ ha ha
would NN had got more out of it with 6 e3?
|Sep-14-09|| ||Sneaky: Had the game had gone 6.Nxe6 Bxf2+ 7.Kxf2 Qxd1 8.Nxc7+ I'm not sure who would be winning.|
|Sep-14-09|| ||just a kid: <sneaky>Let me try to answer that.8.Nxc7+ Kd8 and White is forced to play 9.Nc3,but after 9...Qd4+ 10.Be3(again forced or Black would win the knight)10...Qxe5 11.Nxa8 and after 11...Nc6 Black would trap the Queen with 12...Qb8.|
|Sep-15-09|| ||Once: <YouRang> :-) Well spotted! And thanks for giving me a laugh ... always welcome.|
|Sep-16-09|| ||LIFE Master AJ: NN - Ross Vassilev [D08]
Casual game FICS freechess.org, 09.09.2009
This was the game/problem for Monday; September 14th, 2009.
Black to move, (6... '?').
1.d4 d5; 2.c4 e5;
The Albin Counter-Gambit. (See any good reference work - or a book on this opening - for more details on this system.)
3.dxe5 d4; 4.Nf3 Be6?;
This is not even a good move. (Black gets away with one.)
[The book line is: >/= 4...Nc6; 5.g3, " " when White is clearly better. (See MCO-15, page # 513; column # 16, and all the notes that apply to this column.) ]
This was OK, but it was not White's best move in this position.
[Better was: 5.Qxd4! " " or even 5.e3▒, with White emerging one or two Pawns ahead. ]
Even this move - which leads to a quick win ... was not Black's best play in this position. (The machine prefers 5...Nc6.)
A horrible move ... that sets White up for a simple tactic.

We have also reached the position for the "Chess Games" daily problem.
[Why not the simple: >/= 6.e3, '▒' when Fritz 11 considers White's position to be winning? (" ") ]
6...Bxf2+; (Maybe - '!')
White Resigns, he is losing his Queen.
Please see the CG web page of: NN vs R Vassilev, 2009 for more discussion and analysis of this game.
|Mar-15-10|| ||buk2: 6.Nxe6 would have led to eventual forking of Black's King and rook but then Black's Queen would roll up White's queenside pieces. Anyway, most players give up automatically when they lose their Queen.|
|Mar-23-10|| ||rossvassilev: Short but sweet, huh? Even if white had played 6. Nxe6 and then captured my rook, my queen would then have taken his queen side bishop and rook. The only smart move would have been 6. e3. The Albin may not be as solid as other defences against queen's gambit, but there's plenty of traps for white to fall into.|
|Jun-06-11|| ||FSR: This game is crap and shouldn't be in the database. After 6.e3 White would have been up two pawns for nothing.|
|Jun-11-11|| ||rossvassilev: <FSR: This game is crap and shouldn't be in the database. After 6.e3 White would have been up two pawns for nothing.> true. still a nice finish, though? :)|
|Jun-12-11|| ||AGOJ: No, <Ross>, it is not a nice finish. It is a game where either NN is a total beginner, or was drunk, or the game controls were 30 seconds each for the whole game, or worse, much worse. In any case, not a very edifying game. You are, of course, not to blame for what NN played, and heaven knows I have been guilty of winning against players worse than myself in deplorable fashion, but tell me, are you really proud of this?|
