|Dec-18-15|| ||dnp: for a Friday, it was quite simple.|
|Dec-18-15|| ||al wazir: 31...gxf3 32. gxf3 Qe3+ 33. Kd1 (33. Ke1 Rg1#) Qxf3 34. d7 Rxd7 35. Rxd7 Qh1+ 36. Kc2 Qxe4+.|
I admit that I didn't see this all the way through when I looked at the puzzle position, but it's the line I would have played. I think it's as good as the game line.
|Dec-18-15|| ||morfishine: <32...Rxd7> followed by <33...gxf3> looks fairly routine|
|Dec-18-15|| ||Cheapo by the Dozen: Just like Thursday's puzzle, this one seems super-easy for this late in the week, because there aren't many things to try.|
32 ... Rxd7 (only way to stop the pawn)
33 Rxd7 gf (obvious try; only need to check whether the only obvious counter-try works)
34 Rg1 Qxg1
35 Nxg1 f2 (luckily, the pin in this case didn't win after all)
The last tactical point is that White's knight is effectively trapped, in that it will be lost to a queen fork within a few moves.
|Dec-18-15|| ||goodevans: <morfishine: <32...Rxd7> followed by <33...gxf3> looks fairly routine>|
I saw those two moves and thought "this is all a bit too easy" so 1 looked a bit closer and saw the <34.Rg1> pin. A few more seconds to check that black still has a win after <34...Qxg1> and I was done.
Not exactly difficult but 1 think you have to see all the way to <35...f2> to claim full credit.
|Dec-18-15|| ||sfm: There's a little rule, obvious but handy, to realize here:|
If your unblocked and unthreatened pawn on your 7th rank threatens an opponent's knight then queening can't be stopped.
The knight is especially unfortunate in this matter. In any other case the pawn can be prevented from queening by being captured or blocked by the threatened piece[*].
(Of course exceptions apply is if the kings legally gets involved somehow, by checks or bindings etc.)
Here white resorts to the checks, but they run out.
[*] OK, the exception from  is if the pawn forks two rook/knight on the 8th rank.
Alekhine makes good use of this rule twice in the truly amazing game

35 years ago OMG I had this:

Black to move. White is certainly winning, but it was shortened by 1.-.Kf7? 2.Sd8+. Black resigned, as 2.-,Ke7 3.NxN,KxN 4.f5+ is over too.
All you really need is luck!
|Dec-18-15|| ||morfishine: <goodevans> FWIW: I did; yesterday's puzzle actually helped me with this one, what with both having a slippery pawn maneuver|
|Dec-18-15|| ||wooden nickel: I loved 34.Rg1 QxRg1! 33... Qxh2! is also cute!|
|Dec-18-15|| ||CHESSTTCAMPS: Black has Q+P for N+R, a substantial material advantage. It is true that black must spend a rook to stop a pawn from promoting, but black's queen is ideally placed to harrass the white king and black has ascending pawns of his own.|
Black only needs to make a short calculation before deciding that chopping it off is the simplest approach.
33.Rxd7 (Rg1 Rxd5+ 34.exd5 Qxf3 is winning) gxf3! and now
A) 34.Rg1 Qxg1 35.Nxg1 f2 36.Ne2 (Nh3 f1=Q traps the knight) f1=Q and the threat of f3 is unstoppable.
B) 34.Re1 f2 35.Rxa7 (Re1 moves f1=Q+ also wins the rook) fxe1+ 36.KxQ f3 wins.
C) 34.Rxa7 Qxe2+ 35.Kc1 f2 checkmates after spite checks.
Time for review...

|Dec-18-15|| ||thegoodanarchist: Did anyone remember this puzzle from 11 years ago?|
|Dec-18-15|| ||PJs Studio: I actually got this one. Although not TOO tough because blacks position is pretty desperate!|
|Dec-18-15|| ||dfcx: First tried 32...gxf3 33.d8=Q+ Kh7 34.Re1 and black can't recover from the material disadvantage.|
This forces black to deal with the pawn right away.
32...Rxd7 33.Rxd7 gxf3
A) 34.Re1 f2 35.Rd1 f1=Q 36.Rxf1 Qxf1 and the second pawn is still coming down,
B) 34.Rg1 Qxg1! 35.Nxg1 f2 and promotes next
Other moves? 34...Qxe2+ followed by f2 to promote.
|Dec-18-15|| ||offramp: <thegoodanarchist: Did anyone remember this puzzle from 11 years ago?>|
|Dec-18-15|| ||Virgil A: Not that difficult really. 32...Rd7 is a forced move.|
|Dec-18-15|| ||Tiggler: <jith1207: .... I hope I get one day patience to go through all lines carefully and take time to solve a weekend puzzle cleanly.>|
When I was a kid and had just started playing chess, I noticed that others always said, as a put down or an excuse, "I haven't the patience".

|Dec-18-15|| ||kevin86: Black sacrifices queen and rook to make a super-passed pawn and end up queen for rook and knight and... two pawns ahead.|

|Dec-18-15|| ||Sniffles: Now this is a cute conundrum! Let's call this Machiavellia's last stand.|
First I must get rid of that pawn threat. No problem.
Now my young Jedi on G4, you are my only hope. So let's set up a sucker trap. A queen pin too tasty to refuse.
There! That other pesky rook is gone. Onward and may the force be with you, little pawn.
All black has to do is keep that rook off the G file.
|Dec-18-15|| ||Marmot PFL: All looked forced to me, and not too hard to find (when you know it's a puzzle).|
|Dec-18-15|| ||gawain: All logical--but still pretty deep.|
|Dec-19-15|| ||stst: Step overtime, but thought that ....gxf3 would have advantage, despite of the imminent promotion of White's d7 P.|
