|Feb-03-15|| ||Phony Benoni: Well, at first glance simply 19.Qxd3 and gain a piece, but that's sort of boring and you never know what might happen to a pinned piece. |
Examining the lay of the land a bit, we notice that 19.Rxb7 is on due to the knight fork on d6. After Black moves the queen, then 20.Rxg6 removes the guard of f7. Looks simple nough.
Well, Black can try something like 19.Rxb7 Qd8 20.Rxg6 0-0, and avoid immediate death. But after White retreats the rook from g6 he's gained a pawn as well as a piece. Much ado about little.
|Feb-03-15|| ||diagonalley: i decided to start with 19.RxB instead of going straight for QN7... but maybe that's not the best|
|Feb-03-15|| ||Gilmoy: It goes a bit deeper, actually: <19.Rxb7> Qd8 20.Rxg6 <untouchable>:|

20..Rf8 21.Rxg7 and 22.Nf6+ wins the Q.
20..f6 21.Rxf6 crashes through. Or 21.Rxg7 Rf8 22.Qd1/e2/f3! <Qh5+ is worth more than the Nd3>
Hence <18.Qf1> was only a sham-attack on Nd3 -- it's really a deep-attack on f7! Nice to spot that in a three-second simul think ...
|Feb-03-15|| ||stst: The B is guarding f7 - the target of White Q's attack.|
So one line goes:
19. RxB hxg6
20. Rxb7 QxR
21. Nd6+ (forks K & Q) Kf8
But even if the Black Q did not retake the R after Rxb7, it is difficult to deliver a mate if the f7 P is guarded by the B. One possible line is
19. Rxb7 Qd8 (quite absurd, yes)
20. RxB hxR
21.Qxf7+ and mate soon follows
|Feb-03-15|| ||agb2002: White has a knight for a bishop and two pawns.
The black knight is defenseless and trapped. The knight on e4 is close to Black's royal family and the rook on g5 is ready to eliminate one of the defenders of f7. These details suggest 19.Rxb7:
A) 19... Qxb7 (or 19... Qc8) 20.Nd6+ wins decisive material.
B) 19... Qd8 20.Rxg6
B.1) 20... fxg6 (or 20... hxg6) 21.Qf7#.
B.2) 20... Rf8 21.Rxg7 + - with many threats (Nf6+, Qxd3, Rgxf7, etc.).
B.3) 20... O-O 21.Nf6+ Kh8 22.Rxg7 Kxg7 23.Ngh5+
B.3.a) 23... Kh6 24.Qxd3 with two knights for a rook and a winning attack (24... Rh8 25.Rxf7, etc.).
B.3.b) 23... Kh8 24.Qxd3 wins.
B.3.c) 23... Kg6 24.Qxd3+ Kg5 (24... Kh6 25.Qxh7+ Kg5 26.Qg7+ and 27.Qg4#) 25.h4+ Kxh4 26.Qe4+ Kg5 27.Qg4+ Kh6 28.Qg7#.
B.4) 20... f6 21.Nxf6+ wins.
|Feb-03-15|| ||DarthStapler: Got it|
|Feb-03-15|| ||M.Hassan: "Easy"
White to play 19.?
White is two pawns down
At first one may think to take th knight with the Queen and go a piece up for two pawns but since the Black Bishop is controlling the diagonal, Queen becomes pinned and a move is required to get it unpinned and that will be a loss of tempo while a far better move exists:
<if...Qxb7 20.Nd6+ and picks up the Queen>
20.Rxg6 to remove the supporter of f7
My initial plan was to give up the Rook for two pieces, now that Black has castled to watch f7, the Rook can get more:
<if...Qxf6 23.Nh5+ and that will be a Royal Fork>
White seems better
|Feb-03-15|| ||morfishine: White uses his rooks like a couple of battering rams:|
<19...Qd8> The Queen gets forked after either 19...Qxb7 or 19...Qc8
<20.Rxg6> removes the defender of <f7>; Black is lost: (A) 20...f6
21.Rxf6 gxf6 22.Nxf6+ Kf8 23.Nxh7+ & (B) 20...f5 21.Rxe6+ Kf8 22.Qxf5+
|Feb-03-15|| ||patzer2: <Gilmoy> Thanks for pointing out all of these tactical fireworks in today's Tuesday (19. ?) puzzle came out of one of Garry Kasparov's simuls.|
I might also point out it was a simul from last yeat (i.e. Jan 3, 2014). Not bad for a "retired" World Champion!
<Fairly Promotion> Greatly enjoyed your post showing the two-move mate after 18...Qa6 19. Nd6+ Kd7 20. Rxb7+ Kxd6.
I'll make a note to use that in my lessons with my Grand children, one in particular who really enjoys finding short Queen sacrifice mates.
P.S.: I'd loved to have played 18...Qa6 against Garry and let him pull off that mate in a simul against me. Better I figure than losing a long grind down after 18... Qd8 19. Rxb7 O-O 20. Rxg6 (not 20. Qxd3?? Qxg5! ) 20...fxg6 21. Qxd3 .
fxg6 21. Qxd3 .
|Feb-03-15|| ||cocker: Rxb7, Rxg6, Qxd3 all win.|
|Feb-03-15|| ||zb2cr: I saw 19. Rxb7 and that after the Queen takes on b7, Nd6+ delivers a fork to win Q for R. I have nothing to add to the fine comments by <PHony Benoni>, <Gilmoy>, <agb2002>, and <M.Hassan>.|
|Feb-03-15|| ||OhioChessFan: What exactly is the thought process before 14...Nxe5? "Hey, Kaspy just lost a Pawn. Maybe he'll hang a Knight next."|
|Feb-03-15|| ||KingchecksQueen: Kasparov is the Father of Exciting Chess!|
|Feb-03-15|| ||Penguincw: I had last seen this game on November 5th and December 2nd, so there was pressure on me (by me) to get it right. After a minute of queen sacrifices, I finally saw the rook on b1. :)|
|Feb-03-15|| ||CHESSTTCAMPS: White is down 2 pawns, but would have a material advantage after 19.Qxd3 O-O, with a lot of work left to do. Kasparov undoubtedly would have preferred spending his time in better ways, so he must have played|
19.Rxb7! dominating the black queen and demolishing the black position:
A.19... Qxb7 20.Nd6+ K moves 21.Nxb7 wins
B.19... Qc8 20.Nd6+ K moves 21.Nxc8 wins
C.19... Qd8 20.Rxg6! O-O (to avoid 21.Qxf7#) 21.Nf6+ Kh8 (Qxf6 22.Rxf6 gxf6 23.Qxd3) 22.Rxg7! Kxg7 23.Ngh5+ Kh6 (Kh8 24.Qxd3 mates sooner) 24.Qxd3 Rh8 25.Rxf7 and black can't stop 26 Rxh7+ with checkmate soon.
C.1 20... Qxd6 21.Qxf7+ Kd8 22.Rxe6 finishes
A good argument for Lasker's maxim "When you see a move that delivers a small material advantage, but requires tiresome technique to bring home the point, by all means look for a better move that delivers a clever forced checkmate in 8 or 9 moves."
|Feb-03-15|| ||paavoh: 19. Rxb7 and 20. Nd6 wins. This felt even easier than yesterday's. Probably less cluttered pieces, longer open lines.|
Thanks to <Gilmoy> and <FairyPromotion> for nice alternative variations.
|Feb-03-15|| ||Robin01: Can Rxg6 be played first, prior to Rxb7? It looks playable.|
|Feb-03-15|| ||Cheapo by the Dozen: Fairly complex for a Tuesday.
19 Qxd3 wins, but 19 Rxb7 is stronger. Taking the rook fails to the Nd6 fork, so Black needs to save his queen. 20 Rxg6 then threatens mate at f7, which Black can avert only by castling. If White can save both his rooks quickly enough, he can still pick up the knight, as it's trapped. Black's only chance to prevent that is with the choice 19 ... Qc8. So my main line is
19 Rxb7 Qc8
20 Rxg6 O-O
and mate quickly follows.
|Feb-03-15|| ||Cheapo by the Dozen: <Robin01>,
In that case Black gets 2 rooks for queen and bishop, which leaves him better off -- albeit still lost -- than in the game line.
|Feb-03-15|| ||dfcx: 19.Qxd3 works, but better is
19.Rxb7 Qxb7 20.Nd6+ Ke7 21.Nxb7
If black does not take the rook, for example:
19.Rxb7 Qd8 20.Rxg6 O-O 21.Nf6+ wins
|Feb-03-15|| ||TheaN: Tuesday 3 February 2015 <19.?>|
White is down two pawns, but Kasparov got a very active position in exchange. In the position at hand, white can capture the knight on d3, but might find himself in some trouble after black castles kingside and plays up the f-pawn, due to the pin and discovered attack on the e4 knight.
Instead, white should abuse the centralized black king and the misplacement of the queen and knight with <19.Rxb7!>. Of course, after <19....Qxb7 20.Nd6+ <>> black loses queen for rook and knight and also the right to castle. However if black tries to keep the position together with <19....Qd8>, <20.Rxg6!> strikes again, now attacking f7 with a deadly mating attack, whilst winning a piece and still keeping Nd3 en prise. After <20....O-O>, the only reasonable move to defend against mate, <21.Rg4 > traps Nd3 for real, and black will go down two pieces.
Looking at it like that, Qxb7 is black's best move, but it loses quickly too.
|Feb-03-15|| ||TheaN: Maybe I finished it a bit timid with 19.Rxb7 Qd8 20.Rxg6 O-O 21.Rg4: it's white's best move besides 21.Nf6+!, given black is mated in 13 after 21....Kh8 22.Rxg7! Kxg7 23.Ngh5+ Kh6 24.Qxd3.|
After 21.Rg4, white's idea is to keep the g-rook OTB and bring the queen in via d3. Apparantly crazy ideas for black involve 22....Nc1?! to keep the queen of the b1-h7 diagonal for the time being. 21.Rg4 (as well as Rg5) evaluate +9, 21.Nf6+ is #13.
|Feb-03-15|| ||drleper: <Robin01: Can Rxg6 be played first, prior to Rxb7? It looks playable.>|
Yep, once black recaptures the bishop, white follows with 20.Rxb7 and it's the same thing.
|Feb-03-15|| ||morfishine: Yes, <19.Rxg6> is just as effective: 20.Rxb7 is still threatened and Black's Knight is still hanging|
|Feb-24-16|| ||yurikvelo: Even if do not take into account 18. .. Qc7 blunder, game was lost due to decisive mistake 14. ... Nxe5? |
