Sep-28-12  James D Flynn: The draw agreement is very strange. Black clearly has a won game after 21....Bxg2+ 22.Kxg2 Qd5+ 23.Ngf3 d3 and Blak has only to prepare c3 via Bd2 or Re2 followed by Rc2. No need foe any clever sacrifices,
Sep-28-12  CHESSTTCAMPS: Black has three well advanced pawns on the queen-side for a minor piece, with white's extra piece sitting in a congested mass on the king-side. White has the annoying threat of 22.Bxh3, apparently forcing black to choose the pressure-relieving 21... Bxg2+ or the time-losing 21... Bg4. However, there is a third option that uses black's assets to maximum advantage.

21... c3!! A possibility I saw early, but initially missed the immediacy of the problem posed by the c-pawn. The Bh3 can't be taken safely:

A) 22.Bxh3 Qc4+ 23.Kg2 c2 24.N1f3 cxb1+ 25.Raxb1 d3 wins.

A.1) 23.Ne2 Qxe2+ 24.Kg2 c2 25.Qg1 d3 wins.

A.2) 24.Qa2 Qxa2 25.Rxa2 c1=Q wins.

A.2) 24.Qe1 Rxe1+ 25.Rxe1 c1=Q wins.

B) 22.Nxh3 Qc4+ 23.Kg1 c2 also wins a Q.

C) 22.bc Qc4+ 23.Ne2 Qxe2+ 24.Kg1 dxc3! (the pawn is still worth more than a bishop) 25.Bxh3 c2 wins.

D) 22.Qd3 cxb2 23.Rb1 Bxg2+ 24.Kxg2 c4 25.Qc2 c3 and the pawn roller is crushing.

E) 22.b3 Bxg2+ 23.Kxg2 d3 24.N1f3 c2 25.Qb2 Qe4 and the threat of d3-d2 decides.

Time for review....

Sep-28-12  GooberNumber9: Well, I got the "right" answer for once on a Friday, but I don't feel like it. Seems like 21...c3 is far superior, but I didn't see it. I thought (and still feel like) 21...Bxg2+ was a winning move - the draw mystifies me.
Sep-28-12  CHESSTTCAMPS: Following is a link to play the puzzle position against Crafty EGT with colors reversed:

Good luck!

Sep-28-12  M.Hassan: <CHESSTTCAMPS>
Your line A.1) does not seem to be correct.
24.Kg1 not Kg2
I do not think this line wins. Do you?
Sep-28-12  CHESSTTCAMPS: <M.Hassan> I don't think my error is here, but in overlooking the defense 24.Qf1 in the A) line. So far, I've not found a win against this defense from Crafty EGT, so I have to agree with you.
Sep-28-12  bachbeet: I thought of c3 also but still wasn't sure how it would end up. Then, when I saw the game continuation led to a draw, it's clear c3 was better.

  agb2002: Black has the bishop pair and three pawns for a bishop and two knights.

White threatens B(N)xh3.

Black would recover a piece with 21... Qc4+ if a black pawn were not there. The bishop on h6 can help promote the central pawns. These details suggests 21... c3, creating a GOOT position for White:

A) 22.Bxh3 Qc4+ 23.Kg2 c2 24.Qf1 Qd5+ 25.N1f3 d3 followed by c2 and it seems that the passed pawns will cost White a lot of material.

B) 22.Nxh3 Qc4+ looks similar to A.

C) 22.bxc3 Qc4+ 23.Ne2 Rxe2 24.Kg1 (24.Bxh3 Rb2+ and 25... Rxb1) 24... Bxg2 followed by Qxc3 - + [B+3P vs N].

D) 22.b3 Bxg2+ followed by 23... d3 and ... c2 winning material.

E) 22.Qd3 cxb2 23.Rb1 Bxg2+ 24.Kxg2 c4 and Black has won another pawn and has mobilized three connected passed pawns.

  paulalbert: Considered a lot of ideas, trying to make use of pins etc., or advance of pawns such as d3, but couldn't make anything work. Didn't even consider c3. This one was difficult; makes up for what seemed to be easier ones earlier in week.
Sep-28-12  Patriot: I'm stumped on this one. Taking advantage of a cross-pin with Qc6 or Qe4 looks appealing but neither works. 21...d3 22.Bxh3 Qe2+ 23.Nxe2 dxe2+ 24.Kg2 e1=Q 25.Qxe1 Rxe1 26.Rxe1 is terrible. 21...d3 22.Bxh3 Qe1+ 23.Qxe1 Rxe1+ 24.Rxe1 d2 25.Rd1 Re8 26.Nf3 and black is lost.

The only thing I see is the anti-tactical 21...Bxg2+ or 21...Bg4. 21...Bd2 22.Bxh3 .

21...Bc1 looks interesting since 22.Qxc1 Qe4 (cross-pin) 23.f3 Qd3+ 24.Kf2 Re2+ 25.Nxe2 but I think black is running out of options (and pieces).

I give up!

Sep-28-12  Patriot: Here's what Houdini has to say at 21-ply:

I looked at 21...c3 also but apparently dismissed it too early.

Sep-28-12  QueenMe: Seems to me that 21) ... c3, with its attendant mate threat (err... make that a big-material-losing check threat) is more than enough to be have black accepting a draw like he did. Maybe they were teammates in a final, inconsequential round of play.
Premium Chessgames Member
  Once: <Oxspawn> you are getting better at these puzzles!
Sep-28-12  Helios727: If 21... c3, what happens after 22. bxc3 ?

Sep-28-12  Blunderdome: Many people are appending exclamation points to 21...c3, including, I guess, the admins. But can anyone show a way for white to survive after 21...Bxg2? Seems to me both moves win.
Sep-29-12  Abdel Irada: I'm going to pass on this one. My computer wouldn't boot up last night, and today I woke wondering if I'd caught a virus from it. In any case, thanks to the computer problem and my own sinus infection, I got to the puzzle late, and have no energy to attempt a real solution.

Superficially, <21. ...c3<>> looks strong, but I have yet to find a way to defeat all the possible defenses. And on this occasion, I'm not going to try.


Premium Chessgames Member
  Once: <Blunderdome> I think Patriot's post answers your question. The best move does seem to be c3 but Bxg2 also gives black a small advantage. I don't think either move deserves an exclamation mark, but both should win.

Sep-29-12  vikram2791: I have no idea why they agreed to a draw.22. Kxg2 Qe4+! 23. Kf1 Qxh1.

Look at the diagram:

click for larger view

Black is up on material and is completely on top. His c and d- pawns are close to promotion and White's position is mediocre.

Sep-29-12  Blunderdome: <vikram> White will play 23. Qxe4.
Premium Chessgames Member
  Tiggler: Looked a long time at 21... d3, but found three different white defenses. Could not see anything that works, so chose ...Bg4.
Premium Chessgames Member
  Tiggler: <vikram2791>

From your diagram, after 24. Nhf3 the black queen and two white knights are out of the game. That leaves white Q+R to play against 2R+B+3p. Not all that clear because the N on f3 can help against the d-pawn.

Sep-30-12  Abdel Irada: <vikram2791>: Two observations:

(1) As <Blunderdome> suggests, to avoid an exchange of queens, Black would have to play 22. ...♕d5.

(2) There is absolutely no reason why White can't interpose with 23. ♘gf3 (or, if he prefers, 23. ♘hf3).
