| ksh123: What happens if white plays 20. Qh6 instead of 20. Qf3 ? Does black still have that advantage? |
|

| Bob726: <ksh123> Bg5 traps the Queen |

| ksh123: <Bob726> Thanks, I should have seen that. |

| sfm: Very surprising sacrifices on f2. At first glance Black's pieces do not look dangerous at all, rather undeveloped and backwards. Unfortunately for the white king and queen each and every backward black piece can be developed at their expense. The hard move to find was the silent move 19.-,g6 that forces the white queen to give up the protection of g5. A tremendous game. |

| dzechiel: Great combination! I found the first two moves immediately, but the depth of this whole effort is way beyond my capabilities. |
|
| Oct-22-06 |
| Tenderfoot: That's a pretty brutal combination there. I was guessing the exchange sacrifice, but not for any particularly intelligent reason. |

| bakuazer: believe it or not, but i got this one completely right. 7/7 this week!
in the first minute i was thinking about 17...RXf2, then I noticed amazing 17...g6. I spent like 5 minutes in deciding between the two, after which I realized g6 move comes only later. moves were pretty forced. i even followed the last moves, exactly along the same line [just in move 24. black queen was first taking bishop with a check and then followed with Nd3; I think this doesn't change anything]. good week!! was waiting for it:)
P.S.i don't think though the puzzle is too hard, still, it is beautiful. |

| mgracian: Less difficult than saturday but it is a great combination |

| goldfarbdj: Black can play 17 ... g6 18 Qh6 Bg5 immediately, trapping the queen -- only to run into 19 Bd4+, when 19 ... Kg8 20 Qg7 is mate, so black has to let the queen go. That's one point behind the exchange sac. |

| Vanmeerten: White should play 27. Kd5-f6 |
|

| gus inn: I think it is a position were after 17-Rxf2 - there must be something (as there is ).Just to mention that sometimes
we do not allways need to calculate everything.Almost all indicates that -Rxf2 must at least be playable - and likely more.
But offcourse it is good exercise to calculate as long as possible - and many times necessary. |

| McCool: Hey <chessmoron> in your line, if 26. Qe2+?? then Nxe2. I was looking at the position on move 25... but cannot find a mating combination. Can anyone? |

| aazqua: Knowing that this is a puzzle, the rook sac to allow the bishops to come out seemed pretty obvious to me. The ensuing combination ends up being very deep. To come up with this over the board is very impressive. I wonder if Nataf had this prepared ahead of time? |

| Knight13: Why do puzzles always involve sac? This makes us look at "vulnerable-looking-sac", which makes the puzzle easier, since when we are asked for a tactical puzzle we go "let's see if this sac works." |
|
| Oct-22-06 |
| HelaNubo: <Knight13> Some objections: 1. we should always consider sacs also OTB, and puzzles train us to do so; 2. difficult puzzles may or not involve sacs, and in this case you haven't got it if you saw only Rxf2: the difficult moves are g6, Qg5 and Bh3.
As to the puzzle of today, I got the first moves, though not all the line till the end. My Fritz comes out with an interesting alternative for white: not accepting the sac. Here is the line at deep 17: 18. Rg1! Qf8 19. 0-0-0 Bf6 20. Kb1 b6 21. Rde1 Qe7 22. Ka1 Bb7 -1.02. Black is better but the game is still well playable. |

| kevin86: A nice finish. I answered the first few moves,but I didn't go farther. The attack does come rather sudden. Note: a rare game where the winner captures both rooks-usually,they are sac-ed by the winner-who achieves a quick mate. |

 |
| al wazir: <Knight13: Why do puzzles always involve sac?> Total agreement here! I would like <CG> to come up with more variety. Let's have (1) puzzles where the obvious sacrifice fails and a quiet move wins; (2) puzzles where there is no sac, but one and only one move wins (or draws); (3) traps that win pieces; (4) endgames. |

| bakuazer: i like th endgame puzzles with not many pieces and several pawns, where the solution is a kinda mysterious pawn move, there was one like this maybe some 6-7 weeks ago, and i remember it was a sunday puzzle. I failed that. I like puzzles with quiet moves. do you guys remember the endgame of svidler-ivanchuk in linares this year? |

| Brettwith2ts: No way! I actually figured out a Sunday puzzle! (it took a while, but I got it!) |
|
| Oct-23-06 |
| noendgame: I thought the first two moves jumped off the board. After that it got very tricky with with no room for black to make a mistake. |

| aleister23: 14.Be2??White wants to drive Black's knight away, but the knight moves not backwards but forwards!!! The best move is f4! which appears weakening but .....nope it is not! |

| Fusilli: 9...f4 was probably a novelty at the time. All other games in this database with that move are post-1999. My guess is that Nataf cooked it at home, but who knows, maybe he came up with the whole thing OTB. |
