  Richard Taylor: <Benzol> you are right - I saw it all ! then I had a kind of optical illusion black had to check when I saw ccme 's suggestion

this a great mate in the centre -a smothered! be great to do OTB -

This opening I have played as Black quite a lot (particulary in 1 and 2 minute games lol!!) it's a sharp system (The Averbach var of the Nimzo -Indian)

May-25-05  farrooj: This is very elegant, very simple, smothering the king.. I agree with Jatayu, it was easy..
May-25-05  cade: Rd2 wins also
May-25-05  Stevens: hi all. Thought i had this one with 30...Rxf1, 31. Qxf1 Rc1. But i don't have a board here, so can anyone tell me if this works? If the white rook then captures with 32. Rxc1 black plays ...Qd2 mate. The best move i can see for white is 32. Qe2 but then can black play 32...Qh1+ 33.Qf1 Rxd1+ 34.Kxd1 Qxf1.

Sorry, it's a bit long winded but i wondered if this still won. Without a board to move pieces around i find it hard to visualize.

  Richard Taylor: I just looked up my book of checkmates ["The Art of Checkmate " by Georges Kahn and Victor Renaud (first British Edition, Bell, London 1955)] and this is a variation of the "epaulettes" mate - in such a mate the 'matee' is blocked in on either side;

  Richard Taylor: <Stevens> that's a brilliant idea - I don't know if it works - I look at these positions "in my head" so to speak to try to improve or keep alive what calculating abiliy I have

  Richard Taylor: <Stevens> the trouble is that after 32. ... Rc1 the piece that kind of holds the White King in 'prison' get taken off with 33. Rxe4
May-25-05  chesswonders: <Stevens>, here are the lines:

31.Qxf1 Rc1 32.Rxe4 1-0

If white makes a move other than 32.Rxe4,

32.Re2 Qg3+ 33.Rf2 Rxd1+ 34.Kxd1 Nxf2+ 0-1

32.Qe2 Qg1+ 33.Qf1 Qxe3+ 34.Qe2 Rxd1+ 35.Kxd1 Nc3+ 0-1

May-25-05  Catfriend: Steps to solve this:
1) Whatever black does, it better be forced, as there are many ways white can check the dark king:)

2) If the rook disappears, it's mate in 1! So, se must let it disappear in a forced manner.

3) Is 30..Rxf1+ enough? Not forced enough, worth checking later (and I think it does win, after all). 30..Rb1? No. 30..Re2+ 31.Bxe2 is ok. How about 31.Qxe2? Oh, we must check then... 31..Qh4+ with mate! Hooray!

May-25-05  Stevens: <chesswonders> <richardtaylor> <Catfriend> thanks all. Yes, the simple Rxe4 was what i was missing!
May-25-05  chessfreako: Lol I can't believe I missed this. I noticed Re2+ but forgot about Qh4+!!! Nvm, beat my friends in a round robin todays lol +4=1-0
May-25-05  mandar: <Catfriend>Are u there?
May-25-05  Marco65: White's position seems to be already compromised after 27.Be2? In my opinion White should have played more energically 27.Rd7 with the following possible variations:

a) 27.Rd7 Rc1+ 28.Qxc1 Nxd7 29.Qc7 exf3 30.Rxg7+ Kxg7 31.Qxh2 and White should win (31...Nxb6? 32.Qc7+)

b) 27.Rd7 Qxg3 28.fxg3 Nxd7 29.Bg4 Rcd8 30.b7 Nb8 31.a4 and imho White is better and will win with his 2 passed pawns

c) 27.Rd7 Rf7 28.Rxf7 Kxf7 29.b7 Rb8 30.Qe5 Rxb7 31.Rxg7+ Kxg7 32.Qxh2 exf3

Any comments? Has really White missed a winning chance?

May-25-05  awfulhangover: I saw 30.-Rd2 Still can't see what's wrong with it.
May-25-05  JSYantiss: I saw it too, awfulhangover, but I think the text move Re2+ is faster.
May-25-05  Shokwave: Yeah, I examined RxB first, but couldn't make it work, then saw Rd2 as winning with mate coming and stopped looking, but missed the simpler Re2+.
May-25-05  GiuocoPianoMan: Does anyone here play the Leningrad against the Nimzo? It became a favorite of mine after I read Spassky's book about his best games. He played it frequently when he was a young man.
May-25-05  Dick Brain: The only difficulty in this problem is choosing the clearest win out of several winners like ...Rxf1+ ?!, ...Rd2, ...Rfc2, and of course ...Re2+!

  YouRang: Well, I found 30... Rd2, which I think still wins. I glanced at ... Re2, but didn't see Qh4+ as the reply to 31. Qxe2. Very interesting puzzle.

  kevin86: I can't believe it! I got this one right!

This move reminds me of the more elegant Marshall and Morphy moves of thrusting a piece unto multiple captures. Here it is a rook.

Instead of using a back rank to mate (as is usually the case)-black uses the e1-h4 diagonal to strike,very similar to the fool's mate.

  nasmichael: Correspondence games allow for such depth of attack. Thanks, CC!

Does anyone know what other games and players were in this French Correspondence Championship of 1986?

May-25-05  Timetraveller: <Marco65> 27. Rd7 is a fascinating try, but after 27... g5, Black is threatening both exf3 and Nxd7. Black's position looks kind of loose, I agree, but I don't see a clear win for White and he's going to be down material shortly.
May-25-05  Rama: I like 27. Qe5 ..., threatening Rxg7+ winning Queen. From e5 she also supports the pawn push b7 by hitting the queening square.
May-25-05  pinballace: 30...Rb2 appears to be a win as well.
May-26-05  Marco65: <Timetraveller> I completely overlooked the simple 27.Rd7 g5!, black king seems exposed but I think Black shoud win after e.g. 28.Qe5 Nxd7 29.Rxg5+ hxg5 30.Qxh2 exf3
