|Jul-23-12|| ||Marmot PFL: It looked like a very good attack.|
|Jul-23-12|| ||Garech: Looks like Bacrot is gonna be the punching bag this year.|
|Jul-23-12|| ||mrbasso: 20...Qxe6 looks playable for black.|
|Jul-23-12|| ||kia0708: interesting game|
|Jul-23-12|| ||vinidivici: wow...36.Re8+...winning move. Make this a puzzle of the day maybe Wednesday. Would be very good puzzle with the needing of decent calculation to solve it.
37.Qxg8+ then if
42.Qxe6+ ( )
Correct me if theres a refutation. I was in rush with this line
|Jul-23-12|| ||Marmot PFL: Black took the wrong pawn on move 20, as the passed pawn ties up black's pieces.|
|Jul-24-12|| ||HeMateMe: White's 14. epxd5 seemed odd. It gives black a center pawn roller and opens up the long diagoanl for the g7 black Bishop. |
That kind of move sort of "goes against the rules", but the white pawn on e6 is part of the sharp attack to follow.
|Jul-24-12|| ||JohnBoy: <vini> - this is pretty straightforward. 36.Re8+ is Tuesday at most.|
|Jul-25-12|| ||rilkefan: 20...Qxe6 21.Bxf3 Qxc4 22.Bd1 Qa6 23.Bb2 d5 is -0.6 per stockfish (depth 25, 0.6 Gnodes), while the game line is +0.9. The ugly 18.gxf4 appears to be equal.|
|Jul-25-12|| ||Eyal: After 20...Qxe6! 21.Bxf3 Qxc4 22.Nxe4 Nxe4 23.Rxe4 Qd5! 24.Qxd5 Nxd5 Black wins the exchange (both Ra1 and Bf3 are hanging), but 23...Qd5 is somewhat counter-intuitive and apparently not so easy to see - Akobian, who did this as game-of-the-day on ICC completely missed it and gives 22.Nxe4 as a refutation of 20...Qxe6.|
|Jul-25-12|| ||Willace88: @Eyal there are some nice tactics in your line, but what if white delays the exchange of queens for a little bit: 20...Qxe6! 21.Bxf3 Qxc4 22.Nxe4 Nxe4 23.Rxe4 Qd5! 24.Rad1 and if Black trades Qxd2 then not 25. Rxd2 Nxe4 26. Bxe4 Bc3!, but 25. Nxd2 seems to give White a good game.|
|Jul-25-12|| ||Eyal: <Willace88> I think you got confused - in the line 20...Qxe6! 21.Bxf3 Qxc4 22.Nxe4 Nxe4 23.Rxe4 Qd5! 24.Rad1 Qxd2 the moves 25.Nxd2 or 25...Nxe4 (in case of Rxd2) - are impossible, since the knights are already gone from the board by moves 22-23... after 25.Rxd2 Black wins with 25...Rxf3 26.Rxe7 Rxa3 after which he's a whole piece up.|
|Jul-25-12|| ||Willace88: You're right! I was looking at it before the knight exchange. Qd5 is quite a move.|
|Jul-25-12|| ||sofouuk: <JohnBoy>you're joking, right? a sacrifice on an empty square followed by two variations (37 ... Kd7 and Ke7) which you need to calculate about 8 ply past the first move? tuesday <at most>? what, you think it might be trivial enough for a monday?|
|Jul-26-12|| ||JohnBoy: <sofouuk> - I'm not kidding at all. I don't think the final move was hard to find or terribly subtle. The key is spotting the possibility of Bg4+. Black cannot simultaneously guard the queen and avoid mate. It is a move I would make in blitz - if I ever managed to be good enough to intentionally get to such a position. Tuesday is about right - and I agree that <at most> was unnecessary.|
|Jul-26-12|| ||perfidious: <sofouuk> You're quite right-the main line is a number of moves long-but the variations are all forced, so especially in a long game, it isn't terribly difficult to calculate.|
|Jul-27-12|| ||sofouuk: <perfidious>the issue is not whether it's 'terribly difficult' to calculate, the issue is whether it would be an appropriate puzzle for wednesday, as <vinidivici> suggested. <JohnBoy>, look at today's puzzle, move 33, white to play:|
Geller vs Dorfman, 1976
it's a friday, and the difficulty level is, i would say, virtually identical to white's 36th here; the winning move is a sacrifice on an empty square, followed by a one or possible variations a few moves deep. in fact, i would say the key move is actually easier to find in Geller-Dorfman, because the pinned Rf7 is an obvious target.
again, the issue is not whether either move is 'hard to find' or 'terribly subtle' - neither are - it's whether chessgames normally gives puzzles of this approximate difficulty on a tuesday. they don't. if anything, they're more likely to decide it's too difficult for a wednesday
|Jul-27-12|| ||perfidious: <sofouuk> The lines seem to get blurred after the simple Monday puzzles-at times when suggesting certain ideas, I've been a mite confused myself as to which puzzles best fit which days.|
As to your views on degree of difficulty in Geller-Dorfman vis-a-vis this game, I agree; the move Nh8 more than readily suggests itself in the Geller game, whereas there's a greater amount of calculation to do in the present game, though the variations are forcing. In either case, not at all difficult for a GM once one has got there-the preliminary spadework is the thing.
|Jul-27-12|| ||sofouuk: actually looking at this game again, i'd really be surprised if chessgames used it before friday. the key move in the most obvious continuation is (36.Re8+ Kxe8 37.Qxg8+ Ke7 38.Qg7+ Kd8 39.Qf8+ Kd7) 40.Bg4+, but to realise this move is winning you have to notice that pawn-b5 controls the c6 flight square|
... well sorry to go on about this, but i do think it's one of those positions which is a lot easier to solve once you've already seen the solution. most club players would really struggle to visualise it
|Jul-27-12|| ||JohnBoy: Absolutely, <perf - "the preliminary spadework is the thing">. I found todays' more tricky and missed the pick-up of the piece at the end, which to me was the real point of the puzzle. If one looks at it as purely picking up the X then it is quite easy. Grabbing the bishop is what makes this a Friday puzzle.|
While I disagree with <sofouuk> as to the difficulty of this one, I did not intend to come across as an arrogant twit. Sorry.
|Sep-29-12|| ||vinidivici: i reckon that this puzzle is a little bit tricky, when i solved it i need about 4 minutes but thats for me. Maybe <sofouuk> is right, its too awkward for wednesday, but friday is also too awkward in the reversed way, because i have found the much harder friday puzzle. So it would be very suitable for Thursday puzzle.|
If you long enough member in this site, you must be know that monday or tuesday puzzle most of the case is a basic puzzle, basic ending, or whatever we call very very easy puzzle. It just like a warming up for the next stage. Clearly this puzzle isnt suitable for that. and maybe u have to Look at the puzzle again, i mean "AGAIN" literally.
And, i know there are many others (too many) weak masters in this site but that doest mean this site has to be more harsh and harsh to other members (rookies, just passers by, the players who just play for hobby, etc etc).
