|May-31-06|| ||EmperorAtahualpa: I spotted 30...Rxf2 very quickly.
34...Rb1! is also a very nice move.
|May-31-06|| ||BishopofBlunder: I saw 30...Rxf2 so quickly that I was convinced it must be wrong. So I took extra time trying to refute it. I couldn't find anything that worked, so I finally gave up and discovered, to my delight, that it was correct.|
I don't, however, believe it was an easy puzzle. Especially for Lautier. I was just fortunate to find the move quickly.
And I concur with <EmperorAtahualpa>, 34...Rb1 is a nice move.
|May-31-06|| ||aginis: how about 35.Rdd2
white can try to hold onto a draw.
|May-31-06|| ||patzer2: <RandomVisitor> Agree that 28. Rd2?? was the losing blunder, and that 27. Rab1 to = or 27. c4 =, a move earlier, is better. However, instead of 28. Rad2??, the possibility 28. Qd3= looks good for an even position.|
|May-31-06|| ||Pepino: This one was very easy. (20 sec).|
|May-31-06|| ||patzer2: Did you find today's puzzle "too easy?" If so, here's an interesting puzzle from a possible position in this game after the line 28. Qd3= (instead of 28. Rad2??). |
After 28. Qd3 Bxd5 29. Qxd5 fxg3 30. hxg3 Rbf8 31. Rdd2 Bh6, White can equalize with 32. Rde2 = but is at a significant disadvantage and on the verge of losing if he plays 32. Rdb2? (diagram below). But Why? Let's explore.

[Find Black's best move(s) 32...? (after the possibility 28. Qd3 Bxd5 29. Qxd5 fxg3 30. hxg3 Rbf8 31. Rdd2 Bh6 32. Rdb2?)]
|May-31-06|| ||EmperorAtahualpa: <Beating Topalov just warms my heart. Good job, Mr. Lautier.>|
<chessmoron> LOL, those could be my sentiments exactly.
|May-31-06|| ||RandomVisitor: <patzer2>32...Be3|
|May-31-06|| ||Halldor: The f2-square got my attention instantly as a flashing light before I saw the combination, black rook and queen attacking f2 and the king on the same diagonal as the queen. A rook sac to pin the queen.|
|May-31-06|| ||dakgootje: <<patzer2>32...Be3> Yes thought about that move too, but what about Qg2 then? I think it saves for white|
|May-31-06|| ||patzer2: <Random Visitor> <dakgootje> Indeed 32...Be3! is the solution which gives Black a strong and likely winning attack in this puzzle solution. After 32...Be3! 33. fxe3? Qxe3+ Black has a mating attack.|
The best defense appears to be your suggestion <dakgootje> of 32...Be3! 33. Qg2!? However, after 32...Rg8! 34. Kf1 Qc5! 35. Re2
Qc4 36. Ke1 Bc5 (-2.53 @ 14 depth, Fritz 8), I think White's chances of surviving this are pretty slim.
<Random Visitor> Just curious. What does Rybka give here after 32...Be3!(?)
|May-31-06|| ||patzer2: <aginis: how about 35.Rdd2> If 35. Rdd2, then 35...Bxd5+ 36. Rxd5 Qe1 wins quickly, due to the mate threat 37...Qh1# and the loose Rook on d5 that gets picked off if White tries to avoid the mate (e.g. 37. Kf3 Qh1+ ).|
|May-31-06|| ||YouRang: It took me a minute, but I found it. :-)
Something about this position made it look 'pinnish'. Maybe because Black had two strong bishops and some of White's key targets were aligned on diagonals.
Clearly, the pressure point was the f2 square, which made me (eventually) decide to see what would happen if I sac my rook there. Soon thereafter, I saw the queen-winning pinning.
|May-31-06|| ||beenthere240: I echo the chorus. 34...Rb1 is just too pretty.|
|May-31-06|| ||YouRang: <jajaja><however is 30...Bxd5 winning as well?> I think the same idea still wins, but not as well since it allows Black to pick up an extra pawn.|
31. Rxd5 Rxf2
32. Rxd6 Qc5 (black picks up a pawn)
33. Qxf2 Be3
Not a big deal, but Black has a somewhat more difficult endgame with the isolated e pawn, as opposed to the doubled d & e pawns in the main line.
|May-31-06|| ||DoctorChess: I love those types of pins! 3 for 3.|
|May-31-06|| ||The17thPawn: I would like to take credit for today's puzzle after finding the first three moves. However, 33...Qe3 was not the move I chose and even if I had its doubtful I would have seen 34...Rb1! What's the consensus out there? Does one have to get Rb1! to have solved this puzzle or is black's advantage already winning for certain?|
|May-31-06|| ||RandomVisitor: <patzer2>28. Qd3 Bxd5 29. Qxd5 fxg3 30. hxg3 Rbf8 31. Rdd2 Bh6 32.Rdb2 Be3 33.Kg2 Bc5 34.Re2 -0.96|
|May-31-06|| ||YouRang: <The17thPawn> I don't think it's necessary to figure it out as far as 34...Rb1. If you found the way to win the queen & pawn for a rook & bishop, I would consider this 'finding the solution'.|
|May-31-06|| ||patzer2: <RandomVisitor> Thanks! continuing Rybka's line here <28. Qd3 Bxd5 29. Qxd5 fxg3 30. hxg3 Rbf8 31. Rdd2 Bh6 32.Rdb2?> (32. Rd2 =) <32...Be3 33.Kg2 Bc5 34.Re2>, Fritz 8 indicates play might continue 34...Qb8 35. Qc6 R8f7 36. Qe4 Qf8 37. c4 Rf3 38. Rad2 R7f6 (-2.47 @ 14 depth), when the threat of 39...Bxf2 decides.|
|May-31-06|| ||jperr75108: Not so hard for a Wendsday, although Rb1 is a tough move to see.|
|May-31-06|| ||al wazir: <patzer2: If 35. Rdd2, then 35...Bxd5+ 36. Rxd5 Qe1 wins quickly, due to the mate threat 37...Qh1# and the loose Rook on d5>|
35. Rdd2 Bxd5+ 36. Rxd5 Qe1 37. Rfd2 Qh1+ 38. Kf2 Rf1+ 39. Ke2/Ke3 Qf3#.
|May-31-06|| ||Goumindong: Wow, cant believe I missed that.
And i say that, because just this last night I was playing a game in which i used that EXACT same pin to win a game. I sacked a rook (on a pawn) to draw the queen into a queen-bishop battery pin. He didnt go for it(and i won handily anyway, by virtue of discovered check), but still, everything was the same, except i was coming in from the other side.
|Jun-03-06|| ||Astudent of the game: Sorry, still learning. <Euripides> I see the weakness for white in 25. ... Qc3. And <Longbrow> (You are correct, I did mean b1) I see your point as well. One of the things I don 't understand is leaving the knight pinned with nowhere to move without being taken and still be effective (Ka3 leaves nothing). Would not 26. c4 protect the bishop and the knight taking some of the pressure off the rook and give the opportunity for 27. Kc3? Don't have a chess board here to play this out on so I am trying to visualize options for black.|
|Jun-28-11|| ||plang: Lautier started with only 1 point in his first 6 games but recovered somewhat in the second half with wins against Topalov and Svidler to finish at -2. 20 Na3 was new; Topalov had played 20 Rd2 against Leko at Leon 1996. The rash 20..b4? was answered by 21 Nb5! and Black was in immediate trouble. Topalov, however, misplayed his advantage and then blundered with 28 Rad2? losing quickly. |
<Would not 26. c4 protect the bishop and the knight taking some of the pressure off the rook and give the opportunity for 27. Kc3?>
This is one of the moves Lautier mentions as alternatives; his primary recommendation was 27 Rab1.
34..Rb1! was a pretty shot:
35 Rxb1..Bxd5+ 36 Kg1..Qg3+ 37 Kf1..Qd3+
35 Rf8..Rb2+ 36 Kh3..Qh6+
35 Bf3..Rxd1 36 Bxd1.. Qd3
