|May-16-06|| ||teberius: What about 36. Rb3 37. Rb1, Rc3 ??|
|May-16-06|| ||Gypsy: <teberius: What about 36. Rb3 37. Rb1, Rc3 ???> Caution: beware of Qe6+!|
|May-16-06|| ||2ndNature: <ChessPieceFace>, <dzechiel>: the same here - funny enough I did see Qe6+ and I did see Qb3+ but what I did _not_ see was that White Q from b3 looks at e6 too, so Qe6+ is not possible.|
|May-16-06|| ||eaglewing: <al wazir>, <Ger7ry> It is move 35 for Rg2! |
35. Rgg1 might have been played to threat Rc1 and a playable Qf1 for defense on the c-file. No time for it, we have seen.
35. Rg2 is more passive. Even if White could move again, you have difficulties to improve the defense, so I think Black should go for the win with 35. ... b4, it disrupts the pawn defense.
The line by <Ger7ry: 34. Rgg2 Rxa3 35. ba Qb3+ 36. Rb2 Qxd1 37. Ka2> and now?
You gave and you won a rook (plus pawn) but concerning the threats Qe6+/Qxc8# you cannot sweep in with Rc1, so far from decisive.
And even another defense option exists:
34. Rgg2 Rxa3 35. Qxc8+ Qxc8 36. ba,
maybe the one White should choose.
Or do you see an improvement in the line? I prefer 35. ... b4.
|May-16-06|| ||babakova: <But wait a minute, what about 36...Re2 37.Rb1 Rc3 38.Rgc1 Rxa3+ 39.bxa3 Qa2#? I have neither board nor engine to check on this solution but if it works I like the fact that White would give mate on its next move, too.> Funnily this variation and the realization that <Qe6+> is tricky to crack made me recalculate Rxa3+...|
|May-16-06|| ||United33: nice one|
|May-16-06|| ||dakgootje: I think it was quite hard for a tuesday. Took me almost a minute, which is probably mainly because i first tried some wrong ideas, which of course all didnt work. when i started looking again, looking for more candidate-moves this time i noticed the Rxa3 and after that it didnt take too long before i saw the solution.|
|May-16-06|| ||Manu2: Got it too!!|
|May-16-06|| ||itz2000: got it!|
|May-16-06|| ||mig55: 10 sec, easy one today...|
|May-16-06|| ||zb2cr: Saw it easily!|
|May-16-06|| ||chiguire: Wow, what a great finish, and all the while gaurding c8 and e6. That must have been a frustrating demise for Zhong.|
|May-16-06|| ||Mountainman1: 30 secs, give or take. It was one of those positions were you look at everything BUT the attacking move first.|
|May-16-06|| ||Chessguy007: I thought it was the still winning but less forceful 36... Re2 (because of 37. QxRc8+ QxQc8 though black is still up Queen for a rook).
So 36... Re2
37. Rb1 Rc3! 38. Ka2 Qb3+
39. Ka1 Qxa3!+ 40. bxQa3 Rxa3#
|May-16-06|| ||jmw128: Often, the first thing I look for in a puzzle is if the opponent is about to mate or just ruin your world and how. Then it seems easier, for me, to develop a plan. Here, it is obvious that any plan must cover Qc8+ and Qe6+ in order to be successful. Hence, the real beauty is Qb3+ which covers the e6 square.|
|May-16-06|| ||YouRang: Got it, but only after going through two or three cycles of considering ...Rxa3+ and rejecting it. |
Finally, I satisfied myself that nothing else worked (particularly since White had a dangerous attack as well, with Qe6+ and mate potential).
So I looked harder and found that it was winning (with help from pawn and rook), although White could have put up more resistance with 38. Kb1 instead of 38. Ka2.
|May-16-06|| ||MrsMojoRisin: (MrMojoRisin)We're all dying to know how long it takes you to figure out a puzzle. Please tell us!|
|May-16-06|| ||belka: I realize this is a more difficult puzzle than it should be (I agree), but I wonder why. It shouldn't be diffcult: Rxa3 leaves the White king without any pawn cover, without any defending pieces, trapped on 4 squares, and with Black to move.|
That's a bind. There's always a perpetual if there isn't a win. (And there's going to be a win unless White's threating mate on the move -- and wait a minute, he is! Which in my mind means that the perpetual is not a bad alternative either, because what's your winning plan without Rxa3)
But nonetheless, White is threatening Rc1 already, which I think means curtains for the Black king. I think Rc1, even though it gives 2 rooks for the Queen and it does so with tempo, leaves Black with no king protection and the White Queen is poised to attack. White's position is dangerous.
Anyway, I think this is hard because a brute force solution isn't the right way to solve this.
|May-16-06|| ||kevin86: With white's menacing queen and rook-I knew there was a matter of urgancy. Note that in the solution-black,quite delicately stops the white incursions at e6 and c8. (These things much be done delicately-or you'll hurt the spell"-WICKED WITCH OF THE WEST,Wizard of Oz)|
|May-16-06|| ||al wazir: <eaglewing, Ger7ry> Yes, I meant move 35. Rgg2.|
And I think the best answer to the line <eaglewing> gives is 35...Rxa3 36. Qxc8+ Qxc8 36. bxa3 Qc3,and black picks up at least one more .
|May-16-06|| ||EmperorAtahualpa: Ugh. :( I'm definitely out of shape. Missed this one! Was thinking of the simple Qxe4.|
|May-16-06|| ||beenthere240: <youRang> Try as I might, I can't see how 38. Kb1 (instad of Ka2) makes an iota of difference. Black plays exactly the same.|
|May-16-06|| ||c o r e: I got this one, happily. That's 2 in a row, which is par for the course on a tuesday. :)|
|May-16-06|| ||YouRang: <beenthere240: <youRang> Try as I might, I can't see how 38. Kb1 (instad of Ka2) makes an iota of difference. Black plays exactly the same.> Ach! You are right. Sorry about that.|
Come to think of it, I don't know what I was thinking. My analysis tends to get sloppy once I get 2 or 3 moves deep. :-(
|May-17-06|| ||eaglewing: <al wazir: 35. Rg2 Rxa3 36. Qxc8+ Qxc8 36. bxa3 Qc3,and black picks up at least one more pawn> Okay, agreed. But you need to be careful and there is some counterplay. My main line for this would be:|
37. Rc1 Qd3 38. Rcc2 Kf8 39. Rgd2 Qxa3 40. Rc6 and White tries e.g. to get to Rcxd6/Rd8+/R2d6 and perpetual Rd7/8.
Note that Qb3+ can often be countered by Rb2 and getting Pb5 afterwards.
