|Nov-08-08|| ||KOCMOHAYT: if this masterpiece (in terms of blitz chess) ever becomes a game of the day, it should be named BLITZKRIEG! Congrats to the champion of the world.|

|Jun-29-19|| ||Cheapo by the Dozen: I overlooked that Be5 was preferable before getting White's queen to the h-file. However, Stockfish assures me that the oversight wasn't that big of a deal.|
|Jun-29-19|| ||mel gibson: I would have chosen
As that Knight is a bit of a monster.
It has to be controlled.
I did see the text move but
it looked like a long shot to me -
to sac a Rook for a Knight with an unknown advantage.
Stockfish 10 agrees with the text move.

|Jun-29-19|| ||al wazir: Well, I got the first two moves. But I didn't anticipate 18...Rc8 or anything after that. |
I thought black would play 18...dxe5 or 18...d5 and then castle at the earliest opportunity.
|Jun-29-19|| ||An Englishman: Good Evening: Found the first two moves easily, and it's pretty clear that this constitutes one of those speculative sacrifices where you have to trust your judgment and tactical ability. Loved the threatened smothered mate after 28.Nh5.|
Having written that, what's the best variation after 18...d5 or 19...d5? White seems well off after cxd5,Bc5; e6,f6 vs. either move, but does he have something even better?
|Jun-29-19|| ||Schwartz: After Ng3 a fast few hops are enough.|

|Jun-29-19|| ||patzer2: Since it's a difficult Saturday puzzle, I figured the first move had to be 17. Rxd4! +-. The real difficulty in this puzzle is figuring out the follow-up moves, which are both instructive and complex.|
For an example of how the combination is instructive, after 17...cxd4 the best move is 18. e5 +-. The point of 18. e5 +- is to immediately rip open the exposed King position. Weaker is the slower 18. Rd1 ± to +-, attempting to win back a mere pawn.
As for the complex part of the follow-up, White plays well for the first four moves. However, he appears to make a slight mistake at move five with 22. Bf6? Qc7 ± (+1.37 @ 33 ply, Stockfish 10).
Instead, White should immediately get the Knight into play with 22. Ng3! +- (+2.46 @ 33 ply, Stockfish 10).
White makes a bigger mistake in the follow-up one move later with 23. Ng3?, when this Knight maneuver comes one move too late and allows Black to fully equalize after 23. Ng3? d3 = (0.00 @ 33 ply, Stockfish 10).
Instead, White could have kept a strong and likely decisive advantage with 23. Be5 ± to +- (+1.74 @ 37 ply, Stockfish 10).
P.S.: So where did Black go wrong? For starters, Black should have taken advantage of the opportunity to play 23...d3 = and swindle the draw.
Instead, after 23...Kf8 24. Be5 ± to +- (+1.53 @ 33 ply, Stockfish 10) White soon regained his winning advantage.
Early in this Ruy Lopez opening, our Opening Explorer indicates Masters far prefer development with 4...Nf6 ⩲ to =over losing tempo attempting to exchange Knight for Bishop with 4...b5 5. Bg3 Na5 6. 0-0 ±.
It's far better to develop and equalize early than it is to chase Bishops with Knights, fall behind in development and lose. Having learned that lesson the hard way, I now play 4...Nf6 instead of 4...b5 in this main line variation of the Ruy Lopez.
|Jun-29-19|| ||drollere: like others, i found the first six moves rather easily; they play themselves.|
|Jun-29-19|| ||Hercdon: Black’s boxy defense after move 27 reminds me of my high school days|
|Jun-29-19|| ||King.Arthur.Brazil: Today I was more lucky. I found rightly the combination started with 17.♖xd4. However, I failed into 19.♖e1 which is stronger than mine 19.exd6, because, this move allowed ...♗xd6 while the other don't allow ♗e7? due to obvious 20.exd6 winning some material and attack. Therefore the answer 19....dxe5 is forced! I failled also because chose 28.♘f5 when 28.♘h5 is much superior, not only the imediate 29. ♘g7# which both provide, but the decisive 30.♘f6+ which really decide the game. Generally,|
|Jun-29-19|| ||King.Arthur.Brazil: Generally, I did my comments without a chessboard on my side, only the computer picture (with the available moves of the game). Therefore is an imangination work, that sometimes can fail (like forgeting some ♙ move, that was impossible in another line of analysis, but can happen in this one... as other day. Sorry please.|
|Jun-29-19|| ||thegoodanarchist: Incisive play by LD!
Of course Moro's knight on d4 was a beast worth more than the rook. It HAD to go!
|Jun-29-19|| ||agb2002: Black threatens Nxf3+.
White has Qd3 and Rxd4. Since 17.Qd3 seems to lose some edge, 17.Rxd4 cxd4 18.e5 looks preferable:
A) 18... dxe5 19.Qc6+ Ke7 (19... Qd7 20.Qxa8+ wins a piece) 20.Bxe5
A.1) 20... Rc8 21.Bf6+ gxf6 22.Re1#.
A.2) 20... f6 21.Bc7 Qc8 22.Qd5 f5 (22... Qxc7 23.Re1+ Qe5 24.Rxe5+ fxe5 25.Qxa8 wins decisive material) 23.Qxf5 Qxc5 24.Re1+ Kd8 (24... Kd6 25.Qd5#) 25.Qd5+ recovers material while keeping the attack.
A.3) 20... f5 21.Bc7 looks similar to A.3.
B) 18... Rc8 19.Re1 dxe5 (19... d5 20.cxd5 looks overwhelming) 20.Rxe5+ (20.Bxe5 Be7 21.Bxg7 Rg8 22.Bf6 Rc7 23.Ng3 Kf8 24.Ne4 Bxf6 25.Nxf6 Rg7 followed by Rd7 and d3) 20... Be7 (20... Kd7 21.Qd5#) 21.Ng3 with some compensatio for thed material.
C) 18... Be7 19.exd6 Bf6 (19... Bxd6 20.Qc6+ Ke7 21.Re1+ wins decisive material) 20.Re1+ Kf8 21.Nd2 with the idea Ne4 and c5 looks good for White.
