|Sep-07-09|| ||johnlspouge: Monday (Very Easy)
H Muller vs O Bernstein, 1934 (26…?)
Black to play and win.
Material: Down2P for N. The White Kh2 has 3 legal moves.
Candidates (26…): Qxg2+
26…Qxg2+ 27.Kxg2 Nf4+ then 28…Nxd3
Black now has R+2P for N.
|Sep-07-09|| ||dzechiel: Black to play (26...?). Black has two pawns for the piece. "Very Easy."|
Black goes from a slight disadvantage of effectively a pawn down to up an exchange and two pawns (an easily winning advantage) with...
26...Qxg2+ 27 Kxg2 Nf4+ 28 Kg3 Nxd3
Looking at the position, I wonder what white's last move was. While it might have been 26 Rg2, I think it's more likely that the king was on g3 and black played 25...Qh5+ 26 Kh2. If that's the case, we could have backed this position up by one move and it would still be a good problem.
Time to check.
Got the key move, but guessed wrong on what led up to the position.
|Sep-07-09|| ||dzechiel: John, you beat me to the punch. Taking advantage of Labor Day to stay up late?|
|Sep-07-09|| ||johnlspouge: Got you, Dave!
Off to bed :)
|Sep-07-09|| ||johnlspouge: < <dzechiel> wrote: John, you beat me to the punch. >|
My words exactly... :)
Good night, Dave!
|Sep-07-09|| ||TheBish: H Muller vs O Bernstein, 1934|
Black to play (26...?) "Very Easy"
Black is down a piece for two pawns.
26...Qxg2+ 27. Kxg2 Nf4+ and 28...Nxd3 leaves Black up an exchange and two pawns. White can safely resign.
|Sep-07-09|| ||Formula7: Hmm, Qxg2+ Kxg2 Nf4+ followed by Nxd3 leaves Black the exchange and 2 pawns up.|
|Sep-07-09|| ||notyetagm: A beautiful combination starting with 24 ... c7xg3!!.|
|Sep-07-09|| ||lost in space: I love Monday's:
26...Qxg2 27. Kxg2 Nf4+ 28. Kf2(g3...) 29. Nxd3 and Black is up with 2 's and an exchange. Enough to win easlily
|Sep-07-09|| ||TheBish: <dzechiel: ...Got the key move, but guessed wrong on what led up to the position.>|
Great combo starting on 24...Bxg3! That would have made a good Wednesday or Thursday problem. (Maybe this can be "recycled" in a couple of years after memories fade.)
|Sep-07-09|| ||Jason Frost: 26...Rh6+(why not mess around when you know you've won)|
27. Kg1 Qxg2+
28. Kxg2 Nf4+
|Sep-07-09|| ||Athamas: I saw the obvious queen sacrifice and fork, but I was curious about another line. I looked at another line for a while out of curiosity|
26...Qh4+ 27. Kg1 Nf4 28. Qc4 Re8
At this point it starts getting fuzzy for me.
29. Ne3 b5 30. Qb3 Kh8 or Qa2 Nxg2, Nxf5 Qh3, Ne4 Kh8
I think this is pretty dominating, although it's not nearly as simple and probably has errors. I like the continued attack - I think it should win, although I'm not entirely sure what to do for white here.
|Sep-07-09|| ||ZUGZWANG67: Desperatly looking for mate here. But I can' t see it !|
So 26. ...Qxg2+ 27.Kxg2 Nf4+ and B is up the exchange + two pawns. Time to check.
Ok. That was it...
Let' s see the other' s comments
|Sep-07-09|| ||remolino: 26... Qxg2+ followed by the royal fork will do.|
|Sep-07-09|| ||LIFE Master AJ: 26...QxR/g2+!; and then ...Nf4+.|
|Sep-07-09|| ||k.praneeth surya: 26... Qg2! 27.Kg2 Nf4 losing his queen and he has rook 2pawns for the knight i wondered that white havent seen this combination|
|Sep-07-09|| ||whiteshark: Quite elementary.|
|Sep-07-09|| ||Once: What more is there to say? Everyone else has pointed out the easy Monday finish - a queen sac to drag the white king onto a fork square. Just need to check that black can extricate his knight out of the enemy camp - eg via Nf4 again - to bag the full point. |
One small point may amuse. The forking pattern is what I call a "knight long jump" because the distance from g2 to d3 is a knight move elongated by one square. Here is is in unplugged form (with an extra fork pair in the top left for good measure):

Whenever two target pieces are separated by a knight long jump, then knight forks may be possible. And as long as the pieces are not close to the edge, each knight long jump cluster allows two potential fork squares. In the unplugged diagram, knight forks are possible from a6/ d7 and e1/ f4.
I know, I know, it's a little off-beam. But that's just the weird way that my brain is wired. And I hate repeating what everyone else has said!
|Sep-07-09|| ||kurtrichards: 26. ... Qxg2
(Going for material advantage)
27. Kxg2 Nf4+
(followed by 28. ... Nxd3)
|Sep-07-09|| ||boringplayer: Jason Frost, moving the rook to the h-file allows the K to cross the e-file after ..Nf4+. I don't think the knight gets away, but giving it up for a pawn leaves R+3 pawns for 2 knights, still winning.|
|Sep-07-09|| ||Babar47: An easy queen sac + fork to start the week, all good!|
The game itself is fairly elementary, and a good study on why you shouldn't ignore mate threats.
As already pointed out key moves are 12 ... Bc7 and 24... Bxg3 where black just takes advantages of the lack of any defenders near the king. Good stuff.
|Sep-07-09|| ||2ndNature: <Once> You comments stand out (in a good way) from these self patting "I got this one..." posts. Or is this just the way my brain is wired... ;)|
|Sep-07-09|| ||KOCMOHAYT: the whole combination begining with ... 24 Bxg3 is a good one, queen sac is just the last forcing move|
|Sep-07-09|| ||alphee: Very nice|
|Sep-07-09|| ||Chessox: White wins a rook:
1. Qxg2+ Kxg2 2. Nf4+ forking king and Queen.
Great to finally be a member of chessgames!
