Oct-15-11  Marmot PFL: Didn't have a lot of time for this, but 30...Re8-e3 and 31...Rxg3+ looks winning.

  kevin86: both rook must go-and black is the exchange ahead.
Oct-15-11  Six66timesGenius: Both R8e3 and Nc5! Was decisive attack!
Oct-15-11  jackalope: <Morfishine> I think 32... Rd3 lets White back in the game with 33. Ba4 or am I seeing phantoms?

I saw up to 32... Rf2+ but couldn't visualize a continuation after 33. Ke1 - had to play it out to find 33... Rfg2 34. Ba4 Rxh3 35. Rxh3 Qxh3 36. Qf2 Qh2 37. Qf1 Qg3+ 38. Kd1 Rg1 39. Qxg1 Qxg1+

Now Black has a queen against White's LSB and one rook.

Oct-15-11  JohnAnthony: I found the R8e3 and Rxg3 moves. I followed ...Kf1 with Qf3 though. Need to think more brutally. Love Nunn.
Oct-15-11  lost in space: Saw the idea quite quickly up to 32...Rxf2, so I give me full credit even though I haven't seen 34....Rf3+
Oct-15-11  jackalope: I don't understand 11. Bd3 - White gives up the bishop pair, loses castling and winds up with doubled f pawns. Seems like 11. Bh2 would have been better.

Any comments?

Oct-15-11  scormus: <jackalope: <Morfishine> I think 32... Rd3 lets White back in the game with 33. Ba4 or am I seeing phantoms?>

Well spotted. I also thought 32 ... Rd3 was equally good, in fact was rather pleased with myself for finding this alternative line. Seems it was ??

Oct-15-11  LIFE Master AJ: Several false tries, like 30...RxP/f2+. (Spent quite a bit of time analyzing this one ... before I gave up on it.)

After about 10 minutes, (give-or-take); I would say 30...R/e8-e3! [I probably exceeded the time limit today ...]

The threat is ...RxP/g3+; with a winning attack. If White can conjure a way to counter this, I cannot see it. (I guess he grabs the Knight with 31.BxN/d7, ... and hopes that Black makes a mistake.)

Time to check ...

Oct-15-11  sevenseaman: <jackalope> 33. Ba4 is a very good counter that I overlooked in the <morfishine> line. But your end position with Q against a R and a B should win.
Oct-15-11  jackalope: Thanks <Scormus> - I'm learning a great deal from Kibitzers such as yourself, Mikey00004, Sevenseaman, Morfishine and many others.

This site, with its very active forums, is an incredible resource for anyone wishing to improve their chess skills.

  morfishine: <jackalope> and <sevenseaman> You are right! I know what happened. Mental error in the most literal sense
Oct-15-11  BOSTER: Even during seven years we did not find how black would win after 30...R8e3 if white played 31.Kf1.

From <Crafty> 7 years ago: <<31. Kf1> Qc2 32. Qxe3 Rxe3 33. Kg2 Nf6 34. Rhc1 Qe2 (eval -6.15; depth 15 ply; 750M nodes)>

-6,15 is more than enough for a black win

Oct-15-11  lost in space: ohh, just saw that <hms123> was a bit faster than me. But my wife told me that it is not always best to be first.
Oct-15-11  Helios727: Can white save himself with 31. Qd1 Rxg3+ 32. Kf1 Qf3 33. Rh2 ?
Oct-15-11  hms123: <lost in space>

Are we married to sisters?

:-)

Oct-15-11  Gurn: Would 31. Rhd8 delay a perceived winning combination or change outcome of game?
Oct-15-11  Six66timesGenius: sevenseamen is obsolutely right-
Oct-15-11  sevenseaman: < Six66timesGenius: sevenseamen is obsolutely right-> Thanks <Genius>, I do not even know what you are trying to say!

<obsolutely right> = Was right a long, long time ago, but not today. I take it your browser highlighted the odd spellings, both in the adjective as well as my handle. Have a nice day!

Oct-15-11  sevenseaman: <lost in space> and <hms123>. Thanks for the wonderfully subtle humor you introduce into your posts. We must, all of us make a conscious effort to increase the risibility on this popular site.

<jessicafischerqueen> and <JoergWalter> have conspired to produce a very good one at Kasparov vs Topalov, 1999. Absolute class! Will tickle me for years to come.

Oct-15-11  stst: either Re4 to harass the Q, or even better Re3 to eye for Rxg3...
Oct-16-11  TheBish: K Kachiani vs Nunn, 1994

Black to play (30...?) "Very Difficult", White is up a pawn.

The extra doubled pawn seems to be very strong here: The one on f2 protects the king, and the one on f4 attacks e5, but the knight isn't going anywhere anyway. In fact, Black is willing to give it up, I think.

30...R8e3!

I didn't find any move that comes close to this. Black takes advantage of the pin on f2 to threaten 31...Rxg3+ 32. Kf1 (32. Kh2? Rxh3+) Qf3! with numerous threats.

31. Bxd7

Might as well grab some loot before the ship goes down. No better is 31. Kf1 Qc2! 32. Qxe3 Rxe3 33. fxe3 Qxb1+ 34. Kg2 Qe4+ with an easy win.

31...Rxg3+ 32. Kf1 Qf3

Black is threatening both 33...Rg2 (piling up on f2) as well as 34...Rxg2+ 35. Qxf2 Qxh1+ 36. Ke2 Qe4+! 37. Kd2 (else the Rb1 drops with check) Rd3+ 38. Kc1 (or 38. Kc2 Rc4#) Qc4+ 39. Qc2 (attraction) Qxf4+ 40. Qd2 Qxd2#. How to answer this threat? Let's look at the choices:

(A) If 33. Bb5 Re4! 34. Qxe4 Qxe4 35. fxg3 Qxh1+ 36. Ke2 Qxb1 leaves Black up a queen for a bishop.

(B) 33. Bg4 Rxg4! 34. hxg4 Re4 35. Qxe4 Qxe4 and both rooks are forked, with White's king unable to move to connect them.

(C) 33. Rg1 Rxf2+! 34. Qxf2 (or 34. Ke1 Qe2#) Qd3+ and wins: 35. Qe2 Qxb1+ 36. Qe1 (36. Kf2 Qxg1#) Rxg1+ 37. Kxg1 Qxe1+ cleans up.

(D) 33. Rh2 (best) Re4 34. Qd2 (covering both d3 and e2) and now what? Not 34...f5? 35. Be6+ Kf8 36. Qf6+ and White is mating. Time to retrace my steps...

~~~~~~~~~~~~~~~~~

Nuts! Now I see the error of my ways, but time is running out. The forcing move is best (once again), so instead of 32...Qf3(?), 32...Rxf2+ is crushing. After 32. Kxf2 Qf3+ 33. Ke1 Qxh1+, picking up the other rook as well. If 33. Qxf2 Qd3+ (now that the WQ is out of the way) and wins.
