  Jimfromprovidence: I liked 33…Qc1 34 Qg3+ Kf8 35 Qe1 Ra2++ (to force the king to move away from the knight.

Then comes 36 Kxa2 Qxe1 (winning another piece next move)

Nov-12-11  Gilmoy: <Jimfromprovidence: 35.Qe1 Ra2++> But simply 35..Qxe1 and Black still has mutual threat on the Bf1.

Your diagram wins "only" an I-cut-you-choose decision on White. By minimax, White will save the more-useful minor piece, hence you're getting the Nc3 only if it's <worse> (by some millipawns) than the Bf1.

  doubledrooks: 33...Qc1 threatening 34. Qa1+ or a nasty discovered check wins. For example:

a. 34. Na2 Qb1

a.1 35. Bc4 Rxa2+ 36. Bxa2 Qb4#.

a.2 35. Qg4+ Kf8 36. Qc4 Rxa2+ 37. Qxa2 Qb4#

I overlooked the defense with 34. Qg4+ Kf8 35. Na2 Qb1 36. Bc4. It appears Black then wins with 36...Rc2 37. a5 Qb2+ 38. Ka4 Rc3

But the result is the same, isn't it? Black is up a queen and a pawn vs a bishop or knight instead of a queen and pawn vs. a knight.

Plus to me the double check move lends a nice touch to the puzzle.

Nov-12-11  M.Hassan: <Dr. j: I do not think that is at all "easy">

Agreed, your line is definitely not easy but I still think that it is easier than the normal Saturday category of "very difficult"

Nov-12-11  SuperPatzer77: < Dr. J: I see a few commenters have called today's puzzle "easy". I would like to know if any of them saw the following variation: 33...Qc1 34 Qg4+ Kf8 35 Na2 Qb1 36 Bc4 Rc2! 37 a5 Qb2+ 38 Kh4 Rc3! 39 Nxc3 Qb4# I do not think that is at all "easy".>

Excellent analysis <Dr. J>

Black's strong move is 33...Qc1!


click for larger view

34. Qg4+ (only move to defend against Qb4#) Kf8, 35. Bc4 (best) Rc2!! (threatening Qb2#), 36. a5 (only move) Qb2+, 37. Ka4 Rc3! (threatening Ra3#), 38. Nxc3 Qb4# 0-1 - It is an excellent analysis by <Dr. J> !!

Great game by WGM Gu Xiaobing of China!!

Nov-12-11  SuperPatzer77: <neenu: How about:

34. Na2 Qc1 35. Qa8+ Kg7 36. Bc4>

<neenu> You mean 34. Na2 Qb1?


click for larger view

You should take a look at <Dr. J>'s analysis - similar to yours.

33...Qc1!, 34. Na2 Qb1, 35. Qa8+ Kg7, 36. Bc4 Now Black then wins (see diagram below:)


click for larger view

36...Rc2! (threatening Qb2#), 37. a5 (only move) Qb2+, 38. Ka4 Rc3! (threatening Ra3#), 39. Nxc3 Qb4#

<neenu> It is almost similar to Dr. J's analysis.

SuperPatzer77

Nov-12-11  BOSTER: <Dr. J> Your analysis is very nice, but maybe the winning for black will be not so perfect if white play 33...Qc1 34.Na2 Rf2+ 35.Nxc1 Rxf3+ and then give up one piece.

<Boster> IMO, <Dr. J>'s analysis is 100% perfect.

33...Qc1! 34. Na2 Qb1 (much stronger than 34...Rf2+ (discovered check)) So, you should take a look at <morfishine>'s commentary because it can lead to an inevitable checkmate.

Also, take a look at my answer to <neenu>'s question. <Dr. J>'s analysis is just perfect.

Nov-12-11  dufferps: I can't understand white's resignation.
I see 36.Bc4 as a strong response with no easy victory for black.
Nov-12-11  mathematician: <Dufferps Bc4>
36.Bc4 Rxa2 and mate on b4
Nov-12-11  dufferps: Okay - Now I see -
36. Bc4 Rxa2+ 37. Bxa2 Qb4#.

That explains white's resignation after
35. ... Qb1.

  profK: The humble pawn on c5 is very important to black, almost as much as white's a4 pawn as a constraint to white.

<profK> Amen to that!!!

Nov-12-11  BOSTER: <Super Patzer77> <34...Qb1 much stronger than...Rf2+> . This is sound for you,but not for me.
Nov-12-11  SuperPatzer77: <Boster> You should take a look at <morfishine>'s commentary. You may stand corrected. It is N with a-pawn vs Rook with c-pawn. This ending is not easy for Black to win this game.

Like <Morfishine> said, 34...Qb1! is much more efficient than 34...Rf2+. Most of us would agree with this move - 34...Qb1! because it sure gives Black an easy win.

Nov-12-11  stst: No immediate win, but Bk will gain an advantage after 33......Qc1
34.Bc4 Qa1+
35.Ba2 c4
36.Qd1 Rb3+
37.Qxb3 cxb3
38.Kxb3
and Bk is Q vs W's B&N
Nov-12-11  SuperPatzer77: <stst: No immediate win, but Bk will gain an advantage after 33......Qc1 34.Bc4 Qa1+
35.Ba2 c4
36.Qd1 Rb3+

<stst> 33...Qc1, 34. Bc4 Rf2+ (discovered check), 35. Kb3 Rxf3

Black has a greater advantage with Black Queen and Black Rook vs White Bishop.

SuperPatzer77

Nov-13-11  Grenache: I am not at all impressed by the performance of the Black player.

First of all, one move before the diagram, she or he missed the Queen sac 32. ...Ld5! 33. Lg2: (Nd5: Ra2 and Qc2 mate) 33. ...Rb3+ 34. Ka2 Rc3:+ 35. Ld5: Re3:

Second, on move 27, instead of the automatic capture on h6, 27. ... Rd1!! was winning. After Nd1: Be4+ White is a Queen down against only two minor pieces.

That would have been two very nice problems!

Nov-13-11  SuperPatzer77: Correction to my answer to <neenu>'s question below:


click for larger view

Instead of 36...Rc2?!, the better move is 36...Rxa2+!, 37. Bxa2 Qb4#

Sorry I made a mistake with 36...Rc2?! - It should be 36...Rxa2+! corrected by me. It is because the White Queen on the a8 square doesn't defend the b4 square. That's why I overlooked 36...Rxa2+!

IMO White's only move 35. Qg4+ is much better than 35. Qa8+ because the White Queen has to defend the b4 square against Qb4# as per <Dr. J>'s commentary.
