|Aug-11-11|| ||abuzic: <MostlyAverageJoe: <Crowaholic> Thanks. I never managed to find time to run a computer analysis on this variant. Speaking of the computer analysis, here are the lines after 29 ... Nc6 and 29 ... Bc6 that HIARCS found:>|
29...Rc7 or 29...Rgg7 are other alternatives which probably improve over ...Bc6 or ...Nc6, right?
|Aug-11-11|| ||sevenseaman: <FSR> <Kavalek wrote a column about this game in Chess Life, entitled "Magical Mystery Tour.">|
The way this game has been played by Kavalek, it was anyway destined to be a legend.
|Aug-11-11|| ||rilkefan: <Nb8?[...](30...Kd7 avoids mate 31.Bxc6+ Rxc6 32.Ra7+ Rc7 33.Rxc7+ Qxc7 34.Bxc7 Kxc7 35.Qxe8 Rh6 and white should win)> Thanks, I was trying to figure out why black didn't play that ...Kd7 line, hadn't considered it might be best.|
|Aug-11-11|| ||Garech: 20...Nxa5?? Total suicide.
|Aug-11-11|| ||kevin86: Whoever came up with this pun should be "grilled".|
|Aug-11-11|| ||whiteshark: <Garech: 20...Nxa5?? Total suicide.>
That opens the floodgates, so to say...|
|Jan-25-15|| ||TheBish: I have to disqualify myself from this round of POTD, since I just saw this game a couple of days ago in the archives. Not sure why it was already in the archives before it became a POTD, but it was!|
I remember the continuation went 27. Nxc4!! dxc4 28. Qa4! Rc7 29. Rxb6 ! axb6 30. Qa8+ Nb8 31. Qxb8+! Kd7 32. Qxb6 and finishes with a mate.
|Jan-25-15|| ||Cheapo by the Dozen: Nxc4 snatches a pawn, thus equalizing material with a nice attack, in all lines that I can see, with the prettiest being:|
27 Nxc4 dxc4
28 Qa6+ Kd7
29 Qb5 Qa8
30 Bxc6+ Qxc6
If Black declines the knight, then Rxb6 could be next, with Black not able to play ... Qxb6 in response. If Black tries ... Rb7, White can just pin with Qa6.
|Jan-25-15|| ||Cheapo by the Dozen: Oh well. I missed a better continuation. Ironic, since I'm usually the guy who uses too many non-forcing moves in these puzzles. :)|
|Jan-25-15|| ||FlashinthePan: I don't understand the use of 32.Qb6, wny not 32.Ra7 immediately?|
|Jan-25-15|| ||diagonalley: well... white's N & LSB are not contributing much, which does suggest 27.NxP ... but what then?! (search me) but somehow kavalek foresaw 28.Q-R4!! ... must stop looking at sunday puzzles it's too demoralising :-(|
|Jan-25-15|| ||DWINS: <FlashinthePan: I don't understand the use of 32.Qb6, wny not 32.Ra7 immediately?>|
|Jan-25-15|| ||Chessdreamer: Kavalek in Chess Informant 10 has this game ending with <32.Qxb6 1-0>.|
|Jan-25-15|| ||gofer: The first move is obvious and screams to be played, but as always on Sundays
it is the next 6 moves we have to consider...
<27 Nxc4 ...>
I don't think black can refuse.
28 ... Rgg7
<27 ... dxc4>
<28 Qa4 ...>
Black threatens to win back the lost piece...
28 ... Rc7!
29 Rxb6! bxc6
30 Qa6+ ...
30 ... Kd7
30 ... Rb7
31 Qa8+ Rb8
32 Bxc6! Bxc6
33 Qxb8+ Kd7
34 Ra7+ Ke8
35 Re7+ mating
28 ... Qd7
<28 ... Na5>
<29 Qxa5! bxa5>
<30 Rb8+ Kd7>
<31 Bc6+! Kxc6>
<32 Rxd8 ...>
Black is a whole knight up, but its a lousy knight for the moment.

Hmmm, well I got it, does anyone have any thoughts about <28 ... Na5>? I see they do... ...the queen has to side step the knight, I prefer the
blood and guts option! If black tries to save Be8 he is lost and if he
ignores it I still think he is lost!
|Jan-25-15|| ||morfishine: I went with the ham-fisted <27.Rxb6> |
<kevin86: Whoever came up with this pun should be "grilled"> I agree, but admittedly, Black was boxed in
|Jan-25-15|| ||Penguincw: I got 27.Nxc4 dxc4 28.Bxc6 Bxc6 29.Qxa7.|
|Jan-25-15|| ||thegoodanarchist: I have nothing to say.|
|Jan-25-15|| ||PerpetuallyChecked: Wow. . . all those white pieces actively bearing down on the queen side, except... how to get that Knight involved? Analyzing the soundness of giving the knight for a pawn in order to: 1. activate the bishop - and 2. start the attack is above my pay grade, but I'm glad that I considered this as a possibility. . . .|
|Jan-25-15|| ||agb2002: White has the bishop pair for a bishop, a knight and a pawn.|
Black threatens ... h4 followed by ... hxg3 fxg3 Ne3.
The knight and light square bishop don't take part in the attack against the black king. This suggests 27.Nxc4, threatening 28.Nxb6:
A) 27... dxc4 28.Qa6+ Rb7 (28... Kd7 29.Qb7+ Qc7 30.Qxc7#) 29.Ra4
A.1) 29... Na5 30.Rxa5 Qd7 (30... bxa5 31.Qxb7#) 31.Rc5+ Kd8 (31... bxc5 32.Rxb7 Qa4 33.Rc7+ and 34.Qc8#) 32.Rxc4 looks winning.
A.2) 29... h4 30.Rxc4
A.2.a) 30... Qd7 31.Rxb6 (31.Rxc6+ Qxc6 32.Bxc6 Bxc6 33.Rxb6 axb6 34.Qa8+ Kd7 35.Qf8 also looks winning) 31... axb6 32.Qa8+ Rb8 33.Qxb8#.
A.2.b) 30... hxg3 31.Bxc6 Bxc6+ (31... gxf2+ 32.Kf1 Ne3+ 33.Kxf2 Nxc4 34.Qxb7#) 32.Rxc6+ wins.
A.3) 29... Rgg7 30.Rxc4 Rgc7 31.Rbb4
A.3.a) 31... Nxb4 32.Qxb7+ Kd7 33.Rxc7+ Qxc7 34.Qxc7#.
A.3.b) 31... Qd7 32.Rxc6 Rxc6 33.Bxc6 Qxc6 34.Rc4 + - [Q+P vs R+N]).
B) 27... h4 28.Nxb6+ axb6 (28... Kb7 29.Qa6#) 29.Qa8+ and mate in three.
C) 27... Rb7 28.Qa6 (threatens 29.Na5) 28... dxc4 29.Ra4 transposes to A.
|Jan-25-15|| ||agb2002: My maneuver 28.Qa6+ Rb7 29.Ra4 is much weaker than 28.Qa4 due to the unexpected defense 29... Nf6, trying ... Nd5, when play might continue 30.Bxc6 Bxc6 31.Rxc4 Qe8 (31... Qd7 32.Rxb6 + -) 32.exf6 Rxf6 33.Qa4 Rc7 34.Qa3 Rb7 35.Rb5 +/ - (+1.5 according to Stockfish).|
|Jan-25-15|| ||scormus: great game by Kavalek, super finish. Oh,and I didnt get it.The pun I did'nt get. Didn't get the move either :(|
|Jan-25-15|| ||jindraz: 28...Na5 and I did not see any continuation. But it turns out that simple 29. Qb4 is good enough. It threatens Rxa5 and the knight cannot return as c4 is hanging.|
Kavalek missed several opportunities earlier, either Nxc4 or the much simpler Qc5 b6 Rxa7. The white attack is very strong

|Jan-25-15|| ||vajeer: Wouldn't 27. Qa6+ Rb7 28. Nxc4 win too?|
|Jan-26-15|| ||patzer2: <vajeer: Wouldn't 27. Qa6+ Rb7 28. Nxc4 win too?> Yes indeed, 27. Qa6+ also wins. In fact, Fritz 12 shows its best play transposing to the game line 27. Nxc4: |
