|Jul-29-16|| ||Eusebius: Cool play by Rainer in a hot game against the Russian mastermind. I would have sh... my pants or got a nervous breakdown.|
|Jul-29-16|| ||cunctatorg: Extraordinary pun that fits perfectly the general disposition and vivid approach to the game of both Grand-masters!|
|Jul-29-16|| ||Party Animal: Wow what a game! 22. Qg6 a nice shot!|
|Jul-29-16|| ||kevin86: White will queen!|
|Jul-29-16|| ||julillo: Release the Knaaken|
|Jul-29-16|| ||j4jishnu: splendid, game of the month.|
|Jul-29-16|| ||Bangalorechesslover: @ An Englishman: could you please tell us when and where black missed the win? Or is an analysis still awaited?|
|Jul-30-16|| ||cunctatorg: ... the vivid approach to the game from both Grand-masters... |
The late David Bronstein is of course a legendary Grand-master, a status that Rainer Knaak didn't ever achieve.
However GM Rainer Knaak was (perhaps always) playing pretty "tasty chess"!! Not only fighting chess but also either ambitious or "honest" chess with a fine quality of tactics, a real joy to follow his games!!
There are of course more successful (and even famous) Grand-masters of the same genre like the late Tony Miles or the even more successful Alexander Beliavsky but think about this: how many (so to speak!!..) Grand-masters who are much more successful than Rainer Knaak (and even more successful than Tony Miles!...) were playing a comparatively boring, "cold", "soft" or lazy chess?!? In other words some kind of "tired", "tiring" and perhaps "frightened" chess?!?
Long live the players like these two Grand-masters and particularly hooray for such Grand-masters!!
|Jul-13-19|| ||devere: Nice problem. I managed to see 27.Rxg4 hxg4 28.h5. The trap to avoid is 27.Bxf6 gxf6 28.Qxh5 Rb1+ 29.Rxb1 Qa5+ and White gets checkmated.|
|Jul-13-19|| ||al wazir: 27. Bxf6 gxf6 (27...Nxf6 28. Qxg7#) 28. Qxh5 Reb7 29. Bxe2.|
White is threatening 30. Qxf7#. If 29...Qe7, then 30. Qh8#. If 29...Kg8, then 30. Qxg4+ K moves, and white is a piece up.
I think black's best try is 29...Rb1+ 30. Kd2! But white seems to come out ahead in all lines I've looked at.
|Jul-13-19|| ||JohnBoy: <wazir> - After 27.Bxf6 gf6 I donít believe white has time for 28.Qxh5 as 28...Rb1+ gives black a mating attack.|
|Jul-13-19|| ||mel gibson: I didn't get this one.
Stockfish 10 saw the correct move in only 1 second &
says in 5 minutes of processing:
(27. Rxg4 (♖g3xg4 h5xg4 h4-h5 ♘f6-e8 h5-h6 f7-f6 h6xg7+ ♖e7xg7

I didn't look at it long enough & yes
that move is a blunder
& I made the same mistake.
|Jul-13-19|| ||whiteshark: Is this the <way to easy> week?|
|Jul-13-19|| ||agb2002: White has the bishop pair for a bishop, a knight and a pawn.|
White has Rxg4, Bxe2 and Bxf6. It's worth noticing that 27.Nxf7 loses to 27... Qd1+ 28.Rxd1 exd1=Q#.
27.Bxf6 loses to 27... Qa5+ 28.Rxa5 Rb1+ 29.Kd2 e1=Q+ 30.Kxc2 Ne3+ 31.Rxe3 (31.Kd3 Rd1#) 31... Qc1+ 32.Kd3 Rxe3+ 33.Kd4 Qd2+ 34.Bd3 Qxd3#.
27.Bxe2 looks a bit slow.
27.Rxg4 hxg4 (27... Nxg4 28.Qxg7#) 28.h5:
A) 28... Qd7 29.h6 looks winning (29... g6 30.Qxf6; 29... gxh6 30.Qxh6+ Kg8 31.Bxf6; 29... Bg6 30.hxg7+; 29... Re6 30.Qxg7+ Ke7 31.Qxf7+).
B) 28... Bg6 29.hxg6 wins material while keeping the attack.
C) 28... Ne8 29.h6 also looks winning (29... hxg6 30.Qxh6+ and mate next; 29... Nxd6 30.h7).
That's all I can do today.
|Jul-13-19|| ||malt: Did not get this one today, though I had looked at 27.R:g4, did not link it with 28.h5 |
(27.B:f6? Qa5+ )
Gone with 27.Be2
|Jul-13-19|| ||MrCarciofo: What about: 28 Bxf6, gxB; 29 Qh6+|
|Jul-13-19|| ||Everett: Hey all, hereís a fun line <20...Be4! 21. Nxe4 Nxe4 22. Bxe5 <22.Qxe4?? Qd2+ and Qf2#> Nf2 23. Rh2 Rxe5 24. fxe5 Qd4>|
|Jul-13-19|| ||gofer: <27.Bxf6 gxf6 28.Qxh5 Rb1+ 29.Rxb1 Qa5+>|
<mel gibson>,<devere>, <al wazir> and <JohnBoy>
I felt 27 Bxf6 screamed to be played, but then saw the following forced mate in 7...
27 ... Rb1+!
28. Kd2 e1=Q+ (Rxb1? Qa5+ mating)
29. Kxc2 Qc1+
30. Kd3 Nf2+
31. Kd4 Re4+
32. Kd5 Qxc4+
33. Kc6 Rb6#
What I missed was that <(Rxb1? Qa5+ mating)> isn't <mating> due to Rg3 protecting c3 allowing the bishop retreat;
29 Bc3. So although I discarded 27 Bxf6 in favour of 27 Rxg4 - I did it for perhaps the wrong reasons. But 27 Rxg4
seems to hold the position together more simply. Black has almost no good moves, so 28 h5 and 29 h6 are inevitable.
|Jul-13-19|| ||dorsnikov: I think that it was impossible for Knaak to foresee every one of the moves in this "combination." I think that not even Botvinnik could have foreseen every one of the moves in the precise order as those in this game ?|
|Jul-13-19|| ||patzer2: In attempting to solve today's Saturday (27. ?) puzzle, I quickly found 27. Rxg4!! hxg4 +-.|
However, I blundered on the first follow-up with 28. Bxf6?? which gets White mated in five moves (i.e. 28. Bxf6?? Rb1+ 29. Rxb1 Qa5+ 30. Kf2 e1=Q+ 31. Rxe1 Qxe1#).
The winning follow-up move is of course 29. h5! +- (+11.07 @ 34 ply, Stockfish 10) threatening 26. h6 +-:
< 28.h5! Ne8 29.h6 f6 30.hxg7+ Rxg7 31.Qh6 a5 32.Rc1 a4 33.Rxc2 Rb1+ 34.Kf2 g3+ 35.Kxe2 Qe7+ 36.Kf3 Rh1 37.Qxh1 Rh7 38.Qd1 Nxd6 39.cxd6 Qb7+ 40.Bd5 Qa6 41.Bxf6 Ke8 42.Bc6+ Kf8 43.Kxg3 +- (mate-in-8, Stockfish 10 @ 49 ply)>
P.S.: So where did Black go wrong? Black's game took a significant turn for the worse with 25...Bc2? 26. Rg3! +- (+1.23 @ 31 ply, Stockfish 10).
Instead, 25...Rb1+ 26. Rxb1 Bxb1 27. Rg3 Kh7 28. Bxf6 gxf6 29. Qxh5+ Nh6 30. Ra3 Bg6 31. Qd5 f5 = (+0.09 @ 30 ply, Stockfish 10) would've held it level.
In the opening, instead of 6...h5 7. h4 ⩲, I prefer 6...c5 = as in Black's win in A Smirnov vs B Savchenko, 2008. However, our Opening Explorer indicates most Masters prefer 6...Bxc3 = or 6...0-0 =.
|Jul-13-19|| ||saturn2: <melgibson 27. Rxg4 (♖g3xg4 h5xg4 h4-h5 ♘f6-e8 h5-h6 f7-f6 h6xg7+>|
27. Rxg4 hxg4 28. h5 Ne8 29. h6 f6 <30. h7> seems to me better then your Stockfish move 30 hxg7
|Jul-13-19|| ||Breunor: To add to Patzer 2's comments, the game went back and forth from a computer evaluations standpoint until move 26: |
The ultimate error was 26 kf8:
1) +7.75 (23 ply) 27.Rxg4 hxg4 28.h5 Ne8 29.h6 Kg8 30.Nxe8 Qd1+ 31.Rxd1 exd1=Q+ 32.Kf2 Bg6 33.Nf6+ gxf6 34.Qxg6+ Kf8 35.Qg7+ Ke8 36.Qg8+ Kd7 37.Qxb8 g3+ 38.Kxg3 Re3+ 39.Kf2 Qc2+ 40.Kxe3 Qxc3+ 41.Bd3 Qxc5+ 42.Kd2 Qa5+ 43.Kc2 Qc5+ 44.Kb3 Qd5+ 45.Kc3 Qc5+ 46.Bc4 Qe3+ 47.Kc2 Qf2+ 48.Kb3 Qg3+ 49.Ka4 Qc3 50.Qxa7+ Kd8 51.Qxf7 Qc2+ 52.Kb5
Instead, black can hold with Rd7:
1) +0.73 (24 ply) 26...Rd7 27.Bxe2 g6 28.Be5 Rxd6 29.Bxd6 Rb1+ 30.Rxb1 Qa5+ 31.Kf1 Bxb1 32.Rxg4 Nxg4 33.Bxg4 hxg4 34.Qxg4 Bf5 35.Qe2 Qa1+ 36.Kf2 Qd4+ 37.Kg3 Be6 38.h5 Qc3+ 39.Kh2 a5 40.hxg6 Qh8+ 41.Kg3 Qc3+ 42.Kf2 Qd4+ 43.Qe3 Qxe3+ 44.Kxe3 Bd7 45.Ke4 Bc6+ 46.Kd4 fxg6
It looks like the key here is that if white opens up the attack with Rxg4, sacrificing the exchange, black can return the favor by sacrificing the exchange back and taking out the horrific white knight on d6.
|Jul-13-19|| ||FISHEGGS: I hope he is not from Canada,,,,!|
|Jul-14-19|| ||al wazir: <JohnBoy: After 27.Bxf6 gf6 I donít believe white has time for 28.Qxh5 as 28...Rb1+ gives black a mating attack.>|
You're right. If 29. Rxb1, then 29...Qa5+ wins. Thanks.
