 | | doubledrooks: I went with 41...Rb5, but I admit I didn't examine 42. b4. |
|
| Dec-30-14 | | TheaN: Tuesday 30 December 2014 <41....?> Something is catchy here. This doesn't feel like a Tuesday puzzle at all. At first sight, 41....Rxb2+ or Ba2+ get to mind, given those are the easy options for a Tuesday. Quickly evident though that after respectively 42.Qxb2 Qxc5?? 43.Qxb7# or 42.Kxa2 black is not getting anywhere. The third best 'obvious' move in this position would be <41....a3!>. Black simply puts pressure on the b2 pin, whilst the bishop keeps the white major pieces away from c8. After <42.b3>, 42.Qxa3 Qxc5  , anything else would fail quickly, <42....Bxb3! >. Now black is not shy of throwing the bishop in at b3, because the same bishop is protecting black from checks on the a-file after 43.Rc8+?! Ka7 . White can't capture because of 43.cxb3? Rxb3+ winning the queen. White is best off dodging the threat with 43.Kc1, but I would say that even then Be6, or perhaps the more threatening a2 expose the white queen side. What is catchy though, is that a relatively quiet move as 31....a3 doesn't normally classify as Tuesday. Lets check this one. |
|
| Dec-30-14 | | TheaN: Ah, so that's it. Black utilizes the blocked 2nd rank for a bank rank threat with Rb5!. Glad to see that a3 is the second best move, though. Also, the ridicule looking defense 42.b4! has more pitfalls than you would initially assume. Anand won't fall for it, but it's worth to note 41....a3 might even be the 'safer' option as black is not at risk at all. |

| Dec-30-14 | | rozzatu: viva a3! |
|
| Dec-30-14 | | varishnakov: 41...P-R6 and I miss winning the rook. |
|
| Dec-30-14 | | TheaN: After the relatively simple <40....a3 41.b3 Bxb3 42.Kc1 a2! 42.Rc8?! Ka7 43.cxb3?> the bishop is still immune <43....Rxb3 > the white queen no longer has a spot to defend a1. After <42.Ka1?! Be6!> black proves that just picking off the b-pawn makes the position hopeless for white. I.e <43.Qe1 a2 > with Rb1+ to come |
|
| Dec-30-14 | | Castleinthesky: I was just about to give up and then I saw it. A harder Tuesday. |

| | olinart: ..a3 wins here as well eg ..a3;b3 Bxb3;cxb3+ |
|
| Dec-30-14 | | Cheapo by the Dozen: This is subtle for a Tuesday, but it turns out White's rook is pinned against the empty square g1, as in 41 ... Rc4
42 Rxc4 Qg1#
42 Qxc4 isn't really playable either, because of
41 ... Rc4
42 Qxc4 Bxc4
43 Rxc4 a3
44 b4 Qg1+
45 Ka2 Qc1
46 Kb3 Qb2+
47 Ka4 a2 |
|
| Dec-30-14 | | Cheapo by the Dozen: Definitely blitz. No way these guys play so many failed moves in a slow game. |
|
| Dec-30-14 | | Everett: King safety, lack of squares, back rank pattern, should lead us in the right direction. |
|
| Dec-30-14 | | Longview: I did not see the Q-g1 coming at all. My brain was not in gear to figure out the puzzle to the Q&R pairs on adjacent files. I wanted to advance the A pawn agains the pinned b2 pawn to make progress. It seems I had time. |
|
| Dec-30-14 | | kevin86: I missed this one entirely.. White's rook is pinned again a mating square...by back rank. Instant death! |
|
| Dec-30-14 | | messachess: Oops! That is easy, but I missed it. |
|
| Dec-30-14 | | BOSTER: <CbytheD: White rook is pinned>.
This is nice remark.
<41...Rc4 42.Rxc4 Qg1#>.
This is wrong. |
|
| Dec-30-14 | | PJs Studio: I saw that 41...a3 does nothing. 41...Bb3 almost works but white has 42.Rc8+ followed by 43.Qc5. But even after I gave up and saw 41...Rb5 I STILL did not see the back rank. OTB, I would have but this was speed. Anand was WChamp for a reason |
|
| Dec-30-14 | | stst: See a main line and other softer moves.
Main line:
41.......a3
IF
42. Kc1 PxP+
43. Kb1 Ba2+
44. KxB b8=Q+ |
|
| Dec-30-14 | | stst: my proposed main line is ... slow, missed the quick Q-line |
|
| Dec-30-14 | | TheBish: Topalov vs Anand, 2004 Black to play (41...?) "Easy"
Black is two pawns up, so it would seem that just about anything wins. But not 41...Rxb2+?? 42. Qxb2 Qxc5 43. Qxb7#. There is one move that ends matters fairly quickly: 41...Rb5! 42. b4
Or 42. Rxb5 Qg1+ and mates.
42...Rxb4+ 43. Kc1
Of course 43. Ka1 Rb1 is mate.
43...Rb1+ 44. Kd2 Qb4 trades down to an easy endgame, now three pawns up. |

| | GoldenKnight: The trick is to realize that once the White Rook moves there is mate on g1. My solution was Bb4, which can do the same thing, or White can give up the exchange with some potent threats by Black. Anand's way was more forcing and quicker. |
|
| Dec-30-14 | | Cheapo by the Dozen: Am I missing something, or was my ... Rc4 stronger yet than the game move of ... Rb5? |
|
| Dec-30-14 | | shivasuri4: <Cheapo by the Dozen>, 41...Rc4 loses to 42.Rxc4, when the Bishop's diagonal is blocked. |
|
| Dec-30-14 | | Cheapo by the Dozen: Oh crumb. I made and unmade that mistake several times over the course of the day ... |
|
| Dec-31-14 | | Cheapo by the Dozen: That said, it probably doesn't lose, because of ... b5; I don't think White's mating chances actually get home. |
|
| Dec-31-14 | | shivasuri4: Oh, I completely missed 42...b5. In fact, Black appears to retain a healthy edge after 43.Be2 Qc5 44.b3 axb3+ 45.cxb3 bxc4 46.bxc4 Qf2. The game line remains superior, though. |
