|Apr-24-12|| ||rilkefan: <<LoveThatJoker>: 29. Be4 and 30. Nc2 are phenomenal moves!>|
I get 29.Be4, bottling up the h8-a1 diagonal, but Nc2 is a bit mysterious to me. Stockfish recommends Nb1 with Bc2 to follow after Qe7 (and then Nd2/e4 or Nb3/a5/c6), though Nc2 is only half a pawn worse and still a piece up. Kd2 is as good as the latter. The second best move here appears to be the caveman Rg2.
25...Nxf6 was only half as bad as ...Qxf6 (which was +3). 24...gxf5 was equal. 24.h5 was +1. Finally 22...Ra- or fb8 was almost -1 (if h5 then ...g5, and if g5 first white loses on the black qside squares after ...Qe8/a5), so white should have skipped Ng3 and played h5 immediately then consolidated on the qside with Kd2/Rb1/Bc2.
|Apr-24-12|| ||rilkefan: <sevenseaman>, black presumably wanted to play ...Qa5. Instead ...Qe7 was relatively much better.|
Felt more like a Thursday puzzle to me, as it took me a while to believe g7 was just winning.
|Apr-24-12|| ||viking78: Well, this was a tricky Tuesday puzzle! Spent a lot before seeing the win here which I found knowing that this position must have a solution, and I'm sure in a real game I wouldn't found it. So after trying desperately long time Qxg7 focusing on doubling the rooks on the h file and failed at every possibility I tried the other Queen sacrifice: 31.Qxh7 Rxh7(forced) 32.Rxh7 Kg8(forced) 33.g7(the key, spent over 10 minutes to found it pfew...). Now Nxg7 leads to Rgxg7#; if Kxh7 then gxf8-Q : other moves meet Rh8+ then g pawn promote via g8 or f8 with . That was a really tough Tuesday for me, I'm afraid of what the forthcoming days will bring...|
|Apr-24-12|| ||Once: If 33... Nf6, white cashes in material starting with the discovered check:|
34. gxf8=Q+ Kxf8 35. Rh8+

And now black loses his queen. He can't play 35...Ke7 on account of 36. Rg7# And 35...Ng8 loses to 36. Rgxg8+
This one seemed a little harder than your normal Tuesday.
|Apr-24-12|| ||LoveThatJoker: <rilkefan> Good on you for firing up Stockfish and posting its analysis on here. |
I think the moves are phenomenal because they are purposeful waiting moves: Yes, I agree with Stockfish that 29. Nb1 with the idea of Bc2/Nd2/Ne4 is more to the point (and hence more strongly purposeful - 29. Nb1 also covers against 29...Nc3 for that matter). But seen from a human perspective, to throw in two waiting moves like that in the midst of an attack on the opponent's Kingside is just very cool!
|Apr-24-12|| ||Once: <sevenseaman: I could have laid my last dollar that Black's 30th move would be R to g7. But <30...Qd8> vacating f6 goes over my head. Could someone give me the rationale of this move (presumably no helpmate).>|
My guess is that black wanted to stir up a bit of trouble with Qd8-Qb6-Qb2+. He probably didn't see the strength of white's queen sacrifice.
|Apr-24-12|| ||Nullifidian: I spent a little while looking for a mate, saw that there couldn't possibly be a quick one, and then switched to looking for a decisive advantage.|
31. xh7+ xh7 32. xh7+ g8 33. g7 and now Black's best move is 33... e7.

In this position, my instinct would be to simplify down to a won endgame with 34. h8+ f7 35. xf8+ xf8 36. xf8=+ xf8, leaving White a rook and pawn up.
|Apr-24-12|| ||rhickma4: This seem too hard for a Tuesday.
31.Qxh7+ Rxh7 32.Rxh7+ Kg8 33.g7
Black has no good response to the threat of 34.Rh8+ and 35.gxf8
|Apr-24-12|| ||WinKing: Another tricky mate where black has several options but they all lose.|
33.g7! <took me awhile to see this>
Black has a few options here:
<if 33...Nf6 34.Rh8+ Kf7 35.Rxf8+ Qxf8
36.gxf8(Q)+ Kxf8 <(white is up a rook & winning)>>
<if 33...Qe7 34.Rh8+ Kf7 35.gxf8(Q)+ Qxf8 36.Rxf8+ Kxf8 <(white is up a rook & winning)>>
<if 33...Qf6 34.Rh8+ Kf7 35.gxf8(Q)# <(other queen moves not specified above lead to mate or loss of the queen)>>
<if 33...Rf6 34.Rh8+ Kf7 35.g8(Q)+ <white is up a rook & winning>>
<if 33...Kxh7 34.gxf8(Q) <(white is up a rook & winning)>>
<if 33...Nxg7 34.Rgxg7# <the simplest mate>>
A little bit involved for a Tuesday no?
|Apr-24-12|| ||SamAtoms1980: The Queen has to sac on the right square:
31.Qxh7+ Rxh7 32.Rxh7+ Kg8 33.g7 and Black is in a stew that he can't get out of.
|Apr-24-12|| ||chrisowen: Opening position 31.qxh7+ rxh7 32.rxh7+ kg8
Bind again looks it 33.g7 then queen see on 33...qe7 34.gxf8+ kxf8
35.rg8+ kxg8 36.rxe7 rook up.
A 24.nf5 or door book gxf5 call bluff both look equal to me unless white
has a neat tactical blow slide.
|Apr-24-12|| ||chrisowen: Devious again the ointment all sealed and dealed after ne8.|
Sight it hold n keeps out the bd3 but looks strong for white
Original g7 time round backtack on only move to keep advantage
So loose nf5 n tease lovely storm-trooper 31.qxh7+ and the ball rolls
for white kinside.
|Apr-24-12|| ||gofer: A nice little puzzle for a Tuesday!
<31 Qxh7+ Rxh7>
<32 Rxh7+ Kg8>
<33 g7 ...>
33 ... Nxg7 34 Rgxg7#
33 ... Rf7 34 Rh8#
33 ... Kxh7 34 gxf8=Q mating
33 ... Kf7 34 g8=B+ (g8=Q+ Kf6 35 Rg6#/Qe6#/Qg6#/Qg5#) Kf6 35 Rg6#
33 ... Qf6 34 Rh8+ Kf7 35 gxf8=Q#
33 ... Rf6 34 Rh8+ Kf7 35 g8=Q+ Ke7 36 Rg7+ (Rf7 Qxf7#/Rxf7#) Nxg7 37 Qxd8+ Kf7 38 Rf8#/Qf8#/Qd7#/Qc7#
33 ... Nf6 34 gxf8=Q+ Kxf8 35 Rh8+ Kf7 36 Rxd8 2 rooks up!
<33 ... Qe7>
<34 Rh8+ Kf7>
<35 gxf8=Q+/Rxf8 Qxf8>
<36 Rxf8/gxf8=Q+ Kxf8>
White is a R + P up time to go quietly!
|Apr-24-12|| ||cocker: Failed on a Tuesday; certainly not easy. Third move is the clever one.|
|Apr-24-12|| ||morfishine: I enjoyed watching Black parry the threats, that is until he uncorked <30...Qd8?>|
Put the cork back in the bottle, quick
|Apr-24-12|| ||newzild: Tuesday: 5.30pm - 5.45pm
31. Qxh7+ Rxh7
32. Rxh7+ Kg8
a) 33...Kxh7 34. gxf8=Q
b) 33...Nxg7 34. Rgxg7#
c) 33...Rf7 34. Rh8+ Kf7 35. g8=Q+ Ke7 36. Rh7+
This took me longer than usual for a Tuesday because of a couple of red herrings.
Time to check.
|Apr-24-12|| ||newzild: As a King's Indian player I have to say that I don't think 9...c5 was a very good idea in a strategic sense. It's hard for Black to open the queenside after this move, and White still has the option of castling there.|
|Apr-24-12|| ||ventricule: I have the feeling that 31.Qxg7+ also wins. We then have|
31. ... Nxg7 (forced)
32. Rxh7+ Kg8 (forced)
33. Rh1 Nh5 (only defence against Rh8 mate)
34. Rxh5 Qf6 (same)
35. g7 (again)
If the queen gobbles up the pawn, white is a piece and a passed pawn up and it should be an easy win.
Otherwise, Rh8 after the rook moves ought to be deadly.
Did I miss anything ?
|Apr-24-12|| ||Stormbringer: Nice to get one after yesterday's embarrassment. Didn't calculate to the finish, but saw that White can get two rooks for the price of one. Such a terrible cost. :D|
|Apr-24-12|| ||LoveThatJoker: <ventricule> 31. Qxg7 Kxg7 and Black is better.|
|Apr-24-12|| ||newzild: <ventricule:>
<Did I miss anything?>
Yes, I think you missed one or two things. Firstly, after 31. Qxg7+, it's not true that 32...Nxg7 is forced. Black can also play 32...Kxg7, when White appears to have two possibilities:
a) 33. Rxh7+ Kf6, when 34. g7 Rg8 does not look very convincing for White.
b) 33. gxh7+ Kh8, and again I can't see a convincing continuation for White.
|Apr-24-12|| ||VincentL: "Easy".
31. Qxh7+ Rxh7 32. Rxh7+ Kg8 33. Rgh1. Now the threat is 34. Rh8+ Kg7 35.R1h7+ Kf6 36. Rxf8+ Kf6 37. g7.
This appears to win, but the line is too long for a Tuesday.
Must be missing something. Let´s check.
|Apr-24-12|| ||ventricule: <LTJ><newzild> Thanks mates, solving problems before coffee is a risky bet.|
|Apr-24-12|| ||LoveThatJoker: <ventricule> :) Thanks for the kind note!|
|Apr-24-12|| ||zb2cr: The Queen sacrifice was relatively easy to see; the key move to find was 33. g7!|
