|Aug-25-17|| ||Walter Glattke: 35.-Rh6 36.Qxg3 Nxf3+ 37.Qh3 not Qh2|
|Aug-25-17|| ||Walter Glattke: I had 44.Ra8 Qd8 45.Nb5 threatening Ba5, why 44.Bd7??|
|Aug-25-17|| ||AlicesKnight: Reculer pour mieux sauter....|
|Aug-25-17|| ||diagonalley: missed it completely... (i rate this one as VERY hard)|
|Aug-25-17|| ||groog: Phew, this was hard.|

|Aug-25-17|| ||Lambda: A lot of puzzles are much easier because they're a puzzle rather than a real game. This one is harder. Getting out of a potential queen exchange when you're attacking is a totally natural idea during a real game, but a retreat like that doesn't seem like the answer to a puzzle.|
|Aug-25-17|| ||trnbg: I considered 35.-Nf5, which seems to work well after 36.Qxg3 Nxg3+ 37.Kg1 Rh6 38.Kf2 Rh1, and White can hardly prevent mate on f1.
However, after 36.exf5 Rh6+ 37.Kg1 Qh2+ 38.Kf1 Qh1+ 39.Qg1, it's over...|
|Aug-25-17|| ||bane77: 44.Ra8 Rxb7 -+|
|Aug-25-17|| ||patzer2: Because every option I considered for today's Friday puzzle (35...?) came up losing for Black in my calculations, I gave up and looked at the game solution 35...Qg5!! -- a brilliant tactical Queen retreat and regrouping which I had not even considered.|
Stockfish 8 confirms that 35...Qg5!! -+ (-3.86 @ 36 depth) is clearly winning for Black. The silicon monster also confirms that 35...Qg5!! is the only move that doesn't concede White a decisive advantage.
So finding and rejecting several moves that don't work on this Friday brain buster was at least some consolation for me.
P.S. Black's decisive error was weakening his King position with 34. Kf1?, allowing 34...Rg6! -+ (-3.47 @ 30 depth, Stockfish 8.) Instead, 34. Rf2! = (0.00 @ 36 depth, Stockfish 8) gives White a secure King position and level chances.
|Aug-25-17|| ||prn: So, in the game, White plays 38. Kg1 allowing Black 40...RxG2. What happens if 38. Qh2? I don't see that Black has anything better than a draw. What am I missing?
|Aug-25-17|| ||patzer2: <AlicesKnight: Reculer pour mieux sauter....> As I understand this French phrase, it means a "strategic retreat" or literally "back off in order to get a better jump."|
Very appropriate for today's Friday puzzle solution. Thanks!
|Aug-25-17|| ||patzer2: <prn> If 38. Qh2, Black wins after 38...Qxf3+ 39. Rg2 Kh8! -+ (-8.39 @ 28 depth, Stockfish 8.)|

Monday light, Friday bite.
|Aug-25-17|| ||kevin86: Black wins the queen with a hold and pin format.|
|Aug-25-17|| ||Marmot PFL: Got as far as seeing that black has a promising attack but can't trade queens so that 35...Qg5 looked forced (not normally a move you want to play). Now there is a threat of 36...Nxg2 37 Qxg2 Qh5+ 38 Qh2 Qxf3+. 36 Kg1 doesn't help and the other white pieces are all too far away on the queen side. This is the kind of pitfall white always has to watch out for in the King's Indian.|
|Aug-25-17|| ||Big Pawn: I came up with 35...Qg5.
I tried to make 35...Nxf3 work, as well as 35...Nxg4 and 35...Rh6. Non of them worked. I noticed with the 35...Nxg2 lines that if white played poorly, he could end up with the Queen in front of his King on the h-file or g-file, but there just wasn't enough space for the black queen to move around. The defensive threat of white to trade queens took the tempos away from the attack, so I figured retreating to g5 would actually add tempos, as long as white can't run away in that one move.
Turned out to be correct. I didn't see 36. Be1 but just figured that after 35...Qg5 there were too many threats.
|Aug-25-17|| ||andrewjsacks: I don't like 44.Bd7|
|Aug-25-17|| ||lzromeu: 40.Nc3 weak move
40.QxRg6 and mate is better for white. I suppose.
Maybe a drawn secure
|Aug-25-17|| ||agb2002: Black has a rook for a bishop and a pawn.
White threatens Qxg3 and b7 followed by Nb6 and Nd7.
I've considered Nxg2, Nxf3, Nf5, Qg5, Rh6 and Kh8 and none seemed to work except 35... Qg5, avoiding the exchange of queens and threatening Qh5 followed by Nxf3 or Nxg2.
I didn't find the time today to produce a detailed analysis.
|Aug-25-17|| ||BOSTER: <Big Pawn> How to play after 35...Qg5 36.b7 ?|
|Aug-25-17|| ||Cheapo by the Dozen: Very hard indeed. Even a couple moves into the solution I didn't see where it was going.|
|Aug-25-17|| ||Altairvega: My plan with Nf3 and Rh6 stranded also on the QxQ by white! The solution described as Reculer pour mieux sauter, AlicesKnight the best comment...|
|Aug-26-17|| ||WorstPlayerEver: <patzer2: @prnIf 38. Qh2, Black wins after 38...Qxf3+ 39. Rg2 Kh8! -+ (-8.39 @ 28 depth, Stockfish 8.)>|
SF is right, but one has to calculate the following line to be sure if it is actually winning:
38. Qh2 Qf3 39. Rg2 Kh8 40. b7 Rb8 41. Nb6 Qe4 42. Bf2 Rh6 43. Nd7 Rb7 44. Qh6 Bh6 45. Nf6 (threatens mate) Qb1 46. Rg1 Bg7 47. Rb1 Rb1 48. Kg2 Bf6
|Sep-24-17|| ||Big Pawn: <BOSTER: <Big Pawn> How to play after 35...Qg5 36.b7 ?>|
I was thinking something like 36...Nxg2 37. bxc8=Q Rh6+ 38. Kg1 Ne3+ 39. Qg4 Nxg4 40. fg but it wasn't very convincing.
So then I thought about 36.b7 Rb8 and then continue on like nothing happened, but then after 37. Be1 (like in the game) black doesn't have time to set his pieces up a bit more to attack. He can't play ...Nxf3.
So, finally, it seems like
36. b7 Rxc6!
37. dc Qh5!
Now the discovery is set up and ...Nxf3 is on once the king is forced to g1.
