|Dec-03-11|| ||kevin86: I missed this one entirely:(|
|Dec-03-11|| ||ferri1234: This time I found it!!!|
|Dec-03-11|| ||Rook e2: Solved! Tactics arrise after d4, but they get more power with Rd3 first, else the Queen can take the pawn.|
|Dec-03-11|| ||chrisowen: Well er d3 it look I net in try it harbour in it doubts white as can hold in after it. Seems it provoke tailoring myth it lets off a d4 in trendy queen is played it to fashion rook bequeath it in g5 ng4! Free it the lemon tonic in gratify a5 rook gateway to the south a7 black complicate in matter but for rd3 a tidy good game 21.nd3 age sixes an sevens?|
|Dec-03-11|| ||Jimfromprovidence: 44...Rd3 attacking the trapped bishop stood out to me. Then I saw if white moves a rook over to defend it 45...d4 traps the queen.|
The only angle that concerned me at this point was what if white concedes the piece and tries 45 f5?! to free the queen. Is she still in the game?

What I came up with was black still plays 45...d4 here.

The queen has to reteat to g3 (used below) or h2. Now black plays 46....Rxd1.

Waiting that extra move to take the bishop pays off. Black threatens 47...d3. If 47 exd4, then 47...Qxd4+ wins.
|Dec-03-11|| ||Patriot: Black is up a pawn and white doesn't seem to be threatening anything. The only dangerous moves I could find were 44...Rxe3 and 44...Rd3. 44...Rd3 45.Rcd2 and I didn't see anything. Apparently I didn't look closely enough since 45...d4 leaves the queen with no where to go. So I went with 44...Rxe3. I think what happened is I considered 44...Rxe3 first and was distracted because it looked so good. If I properly analyzed 44...Rd3 I may have seen that it is far superior.|
45.Qxe3 seems to be forced since 45...Rxe3 46.d4 Qxb5 47.dxe3+ and 48.Qxb5 is winning easily. So 45.Qxe3 d4 46.Qd2 d3+ at least gets the piece back with attack.
But I have no idea what 44...Ra5? is! It could be a result of time trouble, but other than that it's not the kind of move you want to look at first. Dangerous moves should always be considered first, like 44...Rd3 or 44...Rxe3.
|Dec-03-11|| ||varishnakov: I found 44...Rd3 45.Rcd2 d4 46.Rxd3 cxd3 as the queen seems to be trapped on move 45.
I began by seeing that d4 is clearly a move wanting to be played, but the queen can simply take on d4 so i moved a rook to d3 first which has the benefit of attacking the undefended bishop.|
|Dec-03-11|| ||James D Flynn: My first thought was 44....Rxe3, but then 45.Qxe3 d4 46.Qc1 d3! 47.Kf1 d3xc2 48.Rxc2 and the square b2 is defended and black has sacrificed a P and is left with weak pawns on c4 and h4 with no clear win. She has some tactical chances with Nd5 bout nothing clear.|
So what else threatens d4? 44...Rd3 of course, either wins the B on D1 or the Q for a rook.
|Dec-03-11|| ||BOSTER: Looking for the forcing line I'd play for beginning 44...Rxe3.White has to play 45.Qxe3 d4 (if 45.Rxe3 d4 and white queen is trapped). 46.Qc1 d3+ 47.Kf1 dxc2 48.Rxc2 Nd5 49.Re2.|
After this I understood that this line gives not too much, but playing d4 I noticed that the white queen's mobility is limited.
So after 44...Rd3 (take away the d4 square from white queen) attacking unprotected bishop d1 with the threat 45...d4 black game is winning.
|Dec-03-11|| ||Patriot: <James D Flynn> Good job on the puzzle! You certainly pointed out things I didn't consider, like weak pawns, and questioned whether 44...Rxe3 is any good as a result. The only thing I would point out is that black really isn't sacrificing a pawn since he started out capturing one. And since black starts out a pawn up, it could mean the line is good. But definitely not as good as 44...Rd3 as you point out.|
|Dec-03-11|| ||morfishine: The most forcing move (following the sound advice of <Patriot>) is <44...Rd3> attacking the Bishop on <d1>. Best for white is <45.Rcd2> but now <45...d4> and White's Queen is trapped. |
I really didn't think it could be this simple and spent a lot of time looking for better moves for white (per <sevenseaman>). Having found none, I assumed it was all a hallucination, and with my daughter looking foward to some fun, free time and besides, the the driving range was waiting, I put it aside and left for the day.
Imagine my surprise when I found black played 44...Ra5 but should've played 44...Rd3. Yes, a pleasant surprised indeed.
Nice work for those who found the correct line and also to <jimfromprovidence> who found a way to extricate the White Queen albeit at the cost of a piece and ultimately the game
|Dec-03-11|| ||TheBish: P Cramling vs H Hunt, 2006|
Black to play (44...?) "Very Difficult"
Observations: White has a very passive bishop, offset by Black's pinned knight. A timely ...d5-d4 will attack White's queen (from Rb5), but the immediate 44...d4 allows 45. Qxd4. The focal point seems to be on the squares e3 and d4. Two major black pieces (Qb6, Rb3) are aiming at e3. Also, Black is already ahead a pawn and bearing down on the b2 pawn, which is adequately defended for now.
What if we capture on e3? It looks like it's adequately defended. However, looking a little deeper we see that Black can follow up with d5-d4 followed by d4-d3, discovered check, with the d3 pawn attacking at least one rook.
44...Rxe3! 45. Qxe3
Or 45. Rxe3 d4 46. Ree2 (queen is trapped) Rxe5 47. fxe5 d3+ 48. Kg2 dxc2 49. exf6+ Kxf6 50. Rxc2 and Black wins the queen and a pawn for rook and knight.
45...d4 46. Qd2 d3+ 47. Kg2 dxc2 48. Qxc2 Nd5 and it looks like Black is better, but it looks like the win a way off.
That's enough time on this one, on to the game!
|Dec-03-11|| ||TheBish: Wow! I saw the trapping idea, but somehow missed the key move, which hits the Bd1, so that 45. f5 (allowing the queen to escape) loses a piece.|
|Dec-03-11|| ||M.Hassan: "Very Difficult" Black to play 44...?
Black is a pawn up and I should add a very impressive pawn structure
With this move, White Queen is trapped
Black is now ahead by a Queen and a pawn vs a Rook and there are still weaknesses in White's camp:
I think it is the time for White to resign and time for me to check
|Dec-03-11|| ||sevenseaman: <M.Hassan> A good shot. With this the White Q has no cogent escape.|
The move is easy and difficult at the same time because there are convincing alternatives. Specifically 44...Rxe3 has misled many; to some extent even 44...d4.
44. Ra5? Out of our range I think. If Harriet won even with this, it only means she was generally a better player than Pia.
|Dec-03-11|| ||standardwisdom: Does someone else feel that right after you solve a Very Difficult Saturday puzzle (or God forbid, an Insane Sunday puzzle) and you reach the kibitzing page, and you see page after page of people asking the innocuous little question - why is this Very Difficult again?|
Thanks - spoilt it for pretty comprehensively. ;-)
|Dec-03-11|| ||changu: yeah,saw dat..Rd3!hie everyone.|
|Dec-03-11|| ||LIFE Master AJ: Incredible! Black missed it?|
|Dec-03-11|| ||LIFE Master AJ: The funny thing was I think I spent 7-8 minutes on this one, tops, I think yesterday was much harder, by a magnitude of 3-4 times ...|
|Dec-04-11|| ||stst: It's again focusing on the Q rather than the K.
IF (A)45.Q flees RxB gaining a piece
IF (B)45.either Rd2, d4 and WQ is trapped and forced to exchange lower (e.g. QxN, at a loss.)
|Dec-04-11|| ||stst: CG needs to play through and think through before rating puzzles.
"Difficult" does not fit when what the players follow a very long sequence.
What the players played may not be optimal (not to insult them.)
There could be much better moves, and then it's not really that "Difficult" when most people see it, without much difficulty(say within a minute.)|
|Dec-04-11|| ||LIFE Master AJ: My ONLY real candidate moves were like:
Kotov said candidate moves should look at 2-3 of the top moves, plus all forcing moves, captures and checks.
|Dec-04-11|| ||CHESSTTCAMPS: Black has pawn+ knight for a passive bishop, superior pawn structure, and tripled majors on the semi-open b-file. The pressure on the backward b-pawn has thrown white on the defensive, but the b-pawn is adequately defended. It took me around three minutes of trying to find combinations against b2 to realize that b2 is not the critical target. It has to be e3, which shields the king and can be taken immediately with obvious advantage.|
Of course. A different attempt to work the b6-f2 diagonal, 44... d4?, fails against 45.Qxd4. Now black profits from a battery, the vulnerable WQ, and the passive white rooks.
A) 45.Rxe3? d4 (winning the trapped WQ) 46.Re4 Rxe5 47.Rxe5 d3+ wins.
A.1) 46.Qxb5? dxe3+ 47.Ke2 Qxb5 leaves black up Q for a R.
A.2) 46.Re2? Rxe5 47.fxe5 Nd7 and one of the white rooks must go.
A.3) 46.Re1 Rxe5 47.fxe5 d3+ 48.Kf1 dxc2 49.exf6+ Kxf6 50.Bxc2 Qxb2 wins the a-pawn and cleans up.
B) 45.Qxe3 d4 46.Qc1 d3+ 47.Kf1(/g2) (any other squares allow Qg1) dxe2+ 48.Bxe2 Nd5! and the threats of Ne3+ and c3 are hard to meet. Already, black is effectively two pawns ahead.
In order to spend some time on the Sunday puzzle, I'm not going to expand the analysis of B. Time for review...
|Dec-04-11|| ||CHESSTTCAMPS: Wow, I belatedly considered 44...Rd3 attacking the bishop and forgot about white's trapped queen. I think Black should win with 44... Re3 - I'll set up Crafty later to check it out.|
|Dec-04-11|| ||CHESSTTCAMPS: <TheBish> and I must be in sync.|
