| ounos: <DoubleCheck: <<error>: Exciting game. Unfortunately for White, 26.Rf7 would have won quickly.>
<<zev22407>: To ERROR if 26)R-f7 a3xb2+ 27)Kxb2 Rxa2+! 28)K-b3 R-a3+ and it is a draw.> 26. Rf7! axb2+
27. Kb1!
And Black should resign
However, should Black continue
27...Qxf7
28. Qxf7 Nc3+
29. Bxc3(Best) Rxd1+
30. Kxb2 bxc3+
31. Kxc3 Rdd8!
Now White can draw with checks Qf6-f7-g6 >
Why not go for the win with 32. Nf6, I don't see black to defend: 32. Nf6 Bg7 33. Qg6 Bxf6 34. exf6 and now:
34. ... Rg8 35. Qxh6#
34. ... Rc7 35. f7, again threatening Qxh6#
This should be winning. |

| wouldpusher: Puzzle would have been more interesting had it started with Black's 30th move. |

| nuwanda: easier than yesterday, in my opinion not even monday-level maybe something like sonday-level
i'm waiting for the day CG comes around with something like W:Ke1 B:Kf3,Rd2
Black to move... |

| whiteshark: 34...Ra1+ 35.Kxa1 Qc3+ 36.K~ Qb2# |

| RandomVisitor: 33...Nd1+ opens up the c3 square for the queen and might win faster. |

| zev22407: to ounos on 27)K-b1?? N-c3+ and now if
28)Bxc3 Rxd1+ and mate next move or 28)Kxb2 Rxa2+ 30)K-c1 R-a1+ 31)K-b2 Nxd1+
32)Kxa1 Q-a5+ 33)K-b1 N-c3+ and mate in 4 moves |

| CHESSTTCAMPS: Black, with an extra piece and significant force directed at a white king that is virtually undefended, should be looking for a quick finish. Unless unnerved by severe time pressure or confused by some mistaken preconceived notion (for instance, that the black queen can't join the attack becaused it must defend g7), black should find the forced mate in 3 that begins with 34....Ra1+!. In general, developing players should become aware of the technical fact that Q+active N is often superior to Q+R in certain positions, especially those involving weakened king positions. |

| patzer2: For today's Tuesday puzzle solution, Black's surprise decoy sacrifice offer 34...Ra1+! leads to a quick mate. See <Zooter>'s post for a good quick analysis. |

| Patriot: This seemed FAR easier than yesterday's puzzle. 34...Ra1+ 35.Kxa1 Qc3+ 36.Ka2/Kb1 Qb2#. Very straightforward. Yesterday's problem was much harder (for me) since I tend to consider checks first (Nxa3+), and failed to consider other threats (Qxa3) before analyzing too deeply. Today's problem falls right into my way of thinking: look at checks first! |

| kirkow: I think 34. ... Qc3 with the double threat Qa1# and Qb2# is a shorter way to win this game. Did I miss something? |

| Patriot: <kirkow: I think 34. ... Qc3 with the double threat Qa1# and Qb2# is a shorter way to win this game. Did I miss something?> How about 35.Qf6+ Kg8/Kh7 36.Qg7#? This is one reason it's best to consider checks first because they are usually the most forcing moves. With 34...Ra1+, white has no time to counter-attack. |
|

| MiCrooks: Typical in these Sicilians with castling on both sides, whoever gets there first wins. Black to move has forced mate with Ra1+, but White to move had several winning lines. White just needs to be careful not to allow Black a tempo with the Queens still on otherwise he can suffer the same fate. |
|

|
| patzer2: <RV>'s suggestion of 33...Nd1+! appears to mate just a bit quicker. One not so obvious possibility is 33...Nd1+ 34. Kc1 Ra1+ 35. Kd2 Qc3+ 36. Ke2 Qe3#. |
|
Mar-31-09
|
| patzer2: It appears 26. Qxe6? was the decisive mistake. Instead, 26. Rf7  or 26. b3 seem to hold slightly better winning chances for White. |

| kevin86: An easy mate in three. Three steps:
1 Force the king to a spot where the queen can check. 2 check with the queen-where he cannot avoid being pinches by the queen at b2-against the side of the board. 3 King either at a2 or b1,the mate comes at Qb2# |

| YouRang: Fairly easy, especially since we know that black must deliver check due to white's serious threats (Qf6+ then Rxd8). Black also has mating threats, if only we have time to get our queen into the attack. This calls for what one might call a 'tempo sac' -- sacrificing material just to buy time (a tempo): 34...Ra1+ 35.Kxa1 serves just that purpose. We sacrificed a rook to put the king on a square that allows our queen to join the attack *with check*: 35...Qc3+ to be followed by 36...Qb2#. |

| gawain: I loved this one! Black must make a forcing move to forestall White's attack. The prime candidate is the Rook check at a1 after which the Queen sails into c3 with check and that's all she wrote. "Easy" is right but easy can be beautiful too.
That's two this week that have been lovely. |

| WhiteRook48: missed a Tuesday puzzle! How stupid!
Black isn't Wilder than white is |
|

| akapovsky: I always have a habit of looking at my opponent's threats.With that in mind Black srikes first with Ra1+ |
|
| Mar-31-09 |
| Eduardo Leon: It was fairly easy. 34. ... Ra1+ 35. Kxa1 Qc3+ and mate next one. Everything is forced. |

| chancho: <ungeneral> the Black King can escape to h7 after 31.Rxf8+ 30.Qf8+ Rxf8 31.Rxf8+ Kh7 32.Rf7+ Qxf7
33.exf7 Bg7 34.Nxg7 Kxg7 35.Rf1 Rf6  |
