| Apr-22-13 | | SamAtoms1980: Looks like <h7> is the square for this week's Monday Motif (queen sac). Then we play the rook to h3, and finally to h8. After that we won't need any more moves. |
|
| Apr-22-13 | | bachbeet: Got it. The Q sac works well because of a well-placed bishop and the rook takes over after the sac. |

 | | agb2002: White has the bishop pair for a bishop, a knight and a pawn. Black threatens 24... fxg3.
Pattern recognition quickly finds 24.Qxh7+ Kxh7 (24... Kf8 25.Qh8#) 25.Rh3+ Kg8 26.Rh8#. |

 | | FSR: I was busily analyzing 24.Bxg6?, thinking this was not that easy for a Monday, when I came to my senses. It's Monday, d'oh! Queen sac! 24.Qxh7+! Kxh7 (24...Kf8 25.Qh8#) 25.Rh3+ Kg8 26.Rh8#. |

| | FSR: <andrewjsacks: This is the O'Kelly variation? That is news to me.> Me too. |
|
| Apr-22-13 | | zb2cr: Black has the obvious mate at g7 protected. So, 24. Qxh7+ with mate in 3. |
|
| Apr-22-13 | | Abdel Irada: <<•> Stock Queen Sacrifice #4? <•>> There are certain sacrificial combinations that occur so often that we call them "stock" sacrifices: the bishop on f7 for a lightning attack against weakened light squares, the bishop on h7 to set up a mating attack with Ng5 and Qh5.... Although this sac is of the queen, it is equally recognizable to experienced players, and equally automatic in certain kinds of positions. <<•> 24. Qxh7† ... > Since this *is* a stock sac, an exclam is hardly necessary. Why reward that which is no more than routine? Now Black has two moves.
< (1) 24. ...Kf8
25. Qh8# >
Remember that square!
<<•> (2) 24. ...Kxh725. Rh3†, Kg8
25. Rh8# >
In case you're *not* yet familiar with this pattern, today's puzzle provides a usefully forthright and uncomplicated example of it. In case you ever find yourself on the defending side of what may become such a position, strive against it by any means, for there is a good chance your opponent will know just exactly how to exploit that entrenched <bishop on f6> to nail your king to the back rank for the coup de grâce. ∞ |

| | FSR: <psmith: The answer to my own question seems to be that 22... Ne6 was the losing move, and that the best chance for defense at that point was probably 22... f6. That's my intuitive judgment and seems to be borne out by a bit of computer (free Rybka 2.2) analysis. Better computer programs might show Black was already lost at that point...?> Sergei Shipov (annotations in Mega Database 2013) gives 20...Rd7 a question mark, and says, correctly, that White has a winning advantage after 22.Bg5. He doesn't mention 22...f6!, which he certainly should IMO. However, Houdini 3 gives White a winning advantage after 23.Bc4+ Ne6 24.Bf6 b5 25.Bxe6+ Qxe6 26.h4, with a crushing attack (+3.04). Instead of 20...Rd7, Shipov recommends 20...c4 with counterplay. Houdini 3 is less enthusiastic, giving 21.f5! exf5 22.Bxf5 (not mentioned by Shipov) as favoring White by +.99. Houdini says that Black should have played either 20...Re8 (+.43) or 20...Qc7 (+.44), making 21.f5? weak in either case because of 21...exf5 intending to take White's e-pawn on the next move. |

 | | Oxspawn: The problem with Monday POTDs is not that they are easy , but that the solution is usually the same. If you 'know' you must sacrifice the queen the opportunity for learning is less. Somewhere round about Tuesday midnight there is a bit of a disconnect in the jump from very easy to rather tricky. If there was more variety on Mondays it might help those of us who fade out towards the middle of the week to make that leap. Just asking…..
24. Qxh7+ Kxh7 (if Kf8 Qh8++)
25. Rh3+ Kf8
26. Rh8++ |
|
| Apr-22-13 | | mistreaver: Monday. White to play. Very Easy.24.?
Pretty straightforward little trick:
24 Qxh7+ Kxh7
25 Rh3+ Kg8
26 Rh8 mate |
|
| Apr-22-13 | | morfishine: FWIW: This game was played quite awhile ago, 1957. Olafsson was 22 & Pilnik was 43...I didn't realize Pilnik was born in 1914 (seems like an awfully long time ago) or that he achieved GM title when he was 38 (seems on the old end, similar to Soltis who was 33) |
|
| Apr-22-13 | | bengalcat47: Very nicely done by Olafsson. In their only other game Pilnik got his revenge with an impressive win in a hard-fought Queen and Pawn endgame. |

 | | OhioChessFan: <BoB: A common mating pattern that every tactician should familiarize themselves with.> Queen sac, Bishop and Rook effect mate on a corner square. One of the first times I saw it was in Chernev's Chess Companion, where he cites this game: Blackburne vs J Schwarz, 1881 |
|
| Apr-22-13 | | James D Flynn: White is down a pawn but both his Bs the R on g3 and his Q are pointing at the Black castled K-side. Black in turn has pressure on the White K position with his Q, B battery on the white squares pointing at g2 and the f4 pawn threatens its only defender the R on g3. However the Black weakness on the black squares around his K is decisive:
24.Qxh7+ Kxh7 25.Rh3+ Kg8 26.Rh8# |

| Apr-22-13 | | mohannagappan: After long break, i am happy to be here.
24.Qxh7+ Kxh7 25.Rh3# |

| Apr-22-13 | | shalgo: <I didn't realize Pilnik was born in 1914 (seems like an awfully long time ago) or that he achieved GM title when he was 38 (seems on the old end, similar to Soltis who was 33)> Well, the FIDE Grandmaster title wasn't even created until 1950, when Pilnik was 36. At that time, he was awarded the IM title, and the only contemporary players who were given the GM title were Botvinnik and the qualifiers for the 1950 Candidates' tournament (plus some of the surviving "old masters"). It would therefore seem that, by getting the GM title in 1952, Pilnik did it about as fast as anyone who didn't qualify for the 1950 Candidates' could do it. |

| Apr-22-13 | | ossipossi: Analysis by G.U.T.s. 1.0:
A very strategically mistake is <7...Bb4>. Best Black pieces (QN & KB) are soon dispatched. More, Black want to build a distance attack with QB + Q, when White has plenty of defending/attacking pieces on the K-side.
<13.bxc3> and Black looses his tricks and slides down fastly. |
|
| Apr-22-13 | | kevin86: Wow! I was looking so hard for a mate at g7.that it took me a minute or so to see the eventual mate at h8! Queen sac,rook check,rook mate at h8=KISMET! |
|
| Apr-22-13 | | poachedeggs: As I looked the game over, 20...Rd7 seemed very bad and the begining of a rapid end...as the N lost a defence of the f6 square...and I see some comments that support this... |
|
| Apr-22-13 | | BOSTER: This is very strange that such player like Pilnik, who had come with powerful 9...g5 in Sicilian 1955, created <the classical hole> on g7, and white queen and bishop occupied h6 and f6, and all <the complex black squares> in the black camp including h8 is weak. When you have two weaknesses like g7 and h7, it is difficult to find the defense. If you saw the game Liren vs Aronian , you should clearly understand what does it mean <the complex of the black squares>. |
