|May-14-16|| ||not not: 33. Rf2?? is it really best move?? I don't understand it at all|
|May-14-16|| ||AlicesKnight: If 31.... Rf6, without opening the White QB diagonal, does White continue 32.Rg2 and trap the BK, or is there something more decisive?|
|May-14-16|| ||Cheapo by the Dozen: Unlike <diagonalalley>, I do not think this is one of the positions in which I'd have channeled my inner Rudolph Spielmann and sacrificed on faith.|
|May-14-16|| ||Al2009: Ftacnick was surely in zeitnot, because he could play 33. Nxg6! (why 33. Rf2?) with no fear for 33...Qxf3+|
After 33...Qxf3+ 34. Rf2 Qd3+ (34...Qd1+ 35. Be1 Kxg6 36. Rxh6+! Nxh6 37. Qxd6+ Kh5 38. Qe5+ leads to mate) 35. Kg1 Qd1+ 36 Kg2 Qg4+ 37. Kf1 Qxg6 38. Rg2 Qxe4 (there are no more checks after 38...Qf7+ 39. Kg1 and then 39...Bd7 40. Rhg5! ) 39. Rxh6+! Nxh6 40. Rg7+ Kh8 41. Qxh6#
|May-14-16|| ||whiteshark: As it turns out, the commitment is a bit of an issue...|
|May-14-16|| ||Ayaend: <3 25.Bf8! <3|
|May-14-16|| ||leRevenant: <nasher: What was the reason white played 33 Rf2 ?>
To protect the pawn on f3 and free up the knight to hop into the fray.|
|May-14-16|| ||morfishine: "Nunn Too Soon"
I got the first two moves but not 33.Rf2
Do I get a Lolli-pop?
|May-14-16|| ||stacase: Getting the first four moves on a Saturday puzzle works for me.|
|May-14-16|| ||ndg2: What if black plays 32...Rg5 instead of Qf7?

Then we have this cute sequence of sacs 33.Rxh6+ Nxh6 34.Qxh6+ (not only Mondays have queen sacs!) Kxh6?? (Kg8 ) 35.Rh2+ Bh3 36.Rxh3+ Rh5 37.Rxh5#

|May-14-16|| ||znsprdx: wow I'd never considered giving up the long diagonal control|
32. Rf2 beyond me = but it worked
|May-14-16|| ||drollere: black played a queen rook down the whole game.|
|May-14-16|| ||RandomVisitor: Black has defensive possibilities with 28...Qf6 that make the earlier move 27.Ndxf4! much better for white.|
|May-14-16|| ||RandomVisitor: 21...h6 followed by 23...hxg5 have to be considered losing ideas. Better for black was something like 21...Bd7 followed by activating the sleeping queen rook 22...Rc8.|
|May-14-16|| ||patzer2: For today's Saturday puzzle position, I went with my instinct and played 31. Nexf4 exf4 32. Nxf4. I didn't see a forced win, but I figured Black's exposed King and the pressure White could quickly bring to bear on the weakened Kingside was easily worth giving up a Knight for two pawns and the attack.|
An instructive, strong move which I missed here is 33. Rf2! , which demonstrates how White precisely builds up his attack while walking a fine line between exchanging material and preparing the attack.
The purpose of 33. Rf2! is to prepare to capture the Rook on the next move with a much stronger attacking position.
In addition to <RV>'s improvement 21...Bd7 =, activating the Queen side pieces, instead of 14...Neg8 I slightly prefer 14...a3 as in A Gutov vs I Saric, 2010, Gelfand vs Kasparov, 1990 and J S Morgado vs R G Alvarez, 2000.
|May-14-16|| ||morfishine: <ndg2> Thats gorgeous|
|May-14-16|| ||agb2002: White has a bishop and a knight for the bishop pair.|
The best defenders of the black king seem to the pawns on e5 and f4 because they hinder the maneuvers of the white pieces. This leads to consider 31.Nexf4:
A) 31... exf4 32.Nxf4
A.1) 32... Rg5 33.Rxg5 Qxg5 34.Rg2
A.1.a) 34... Qxf4 35.Rg7+ Kh8 36.Rf7+ and mate soon.
A.1.b) 34... Qe7 35.Rg7+ Qxg7 36.Bxg7 Kxg7 37.Qg3+ with more or less balanced material but a dangerous initiative. For example, 37... Kf6 38.Qg6+ (38.Qxg8 Bh3+ - +) 38... Ke7 39.Qh7+ Kf6 (39... Kf8 40.Ng6+ Ke8 41.Qxg8+ Kd7 42.Qf7+ Kd8 43.Qe7#) 40.Nh5+ Kg5 41.Qxg8+ Kxh5 42.Qf7+ Kh4 (42... Kg5 43.Qe7+ wins the d-pawn at least) 43.Qf6+ Bg5 44.Qxd6 looks winning.
A.2) 32... Bd7 33.Nxg6 Kxg6 34.Rg2+ Kf7 (34... Bg5 35.Rhxg5+ wins decisive material) 35.Rxh6 Nxh6 36.Rg7+ wins decisive material.
A.3) 32... Rg7 33.Bxg7
A.3.a) 33... Kxg7 34.Rg2+ Kf7 35.Rxg8 Kxg8 36.Rxh6 with two extra pawns and a winning attack (36... Qg7 37.Rg6).
A.3.b) 33... Qxg7 34.Rg2 Qf8 35.Rxg8 Kxg8 (35... Qxg8 36.Rxh6+ Kg7 37.Rg6+ wins) 36.Rxh6 with the same conclusion as A.3.a.
A.4) 32... Rf6 33.Bxf6 Qxf6 (33... Nxf6 34.Rxh6+ + - [R+2P vs B] and a winning attack) 34.Rg2 Ne7 (34... Qxf4 35.Qxf4 wins; 34... Bd7 35.Rg6 Qf8 36.Rxg8 as in A.3) 35.Rg6 Nxg6 36.Rxh6+ Kg7 37.Rxg6+ wins decisive material.
B) 31... Rf6 32.Rg2 probably ends up transposing to A.4.
|May-14-16|| ||agb2002: <morfishine: <ndg2> Thats gorgeous>|
I fully agree!
|May-14-16|| ||mel gibson: How come I don't get some Tuesday puzzles but I saw this straight away?|
|May-15-16|| ||Al2009: <patzer2>
33.Rf2? is just a blunder, it is not a strong move.
Read better and see my analysis above after
|May-15-16|| ||Moszkowski012273: I disagree,, 33.Rf2... was pretty awesome.|
|May-16-16|| ||Al2009: <Moszkowski012273>
You can disagree, but you are uncapable to show me a good analysis, supporting your idea.
Sorry, chess is like math, it is not simply "opinions", it is analysis and calculations.
That's the same with <patzer2>, patzer2 will always remain a patzer, because if you want to play chess at good levels, you have to make accurate calculations and analyse the variations...
|May-16-16|| ||Moszkowski012273: I looked at your analysis it's quite faulty, perhaps you should double check before posting. But good luck with that whole "judge and jury" thing you got going on here.|
|May-17-16|| ||AvidChessMan: I can't explain why, but I really liked 31. Nef4 ef4 32. Nf4. I could not see past that. And, I could not see any better options for white. The only reason I can think for 33. Rf2 (which I agree is not a sharp move) is to protect the b pawn and prevent the f4 knight from a future pin, in case of a pawn exchange, vies-a-vie white bishop to g4.|
|May-17-16|| ||Moszkowski012273: And yet, it IS, a very sharp move.|
