  zanzibar: A deep position where White looks to have the K-side attack going strong, but must find the one critically right move to correctly press the attack:

(White to move after 20...Re6 x Bd6)

Yes, there's a sac somewhere in there, but it's in addition...

Find this one and you're officially an "attacking fool".

Jun-10-18  Retireborn: 1.Ne4! - leaps to the eye, really. White threatens Nxf6 mate and if the knight is captured, Rxg7+, Bxf4 and Rg1.

Does 1.Qxf6 work after 1...g6 2.Rxg6+ fxg6 3.Qxg6+ & 4.Qxd3? Two pawns up, but presumably not the intended solution.

  zanzibar: You're a good yolk <RB>, and 1.Ne4! is indeed the move to find (or, 21.Ne4!).

This game is on <CG>: Reti vs Bogoljubov, 1919 (&m=21)

Reti didn't play 21.Ne4, and so you can see one follow-up to 21.QxNf6 there.

Aside- after 21...g6 it's not clear what White's best move is, Reti picked 22.Nf1. Other choices might be 22.Rg4 or 22.Nb3. The line you give does look inviting, but after 24.Qxd3 White's king is too exposed, and defenders a little too unorganized.

(Two pawns up, but...)

E.g. 24...Bxh2 (or 24...Qh6) and if 25.Kxh2? Rf4 and White is in big trouble.

Jun-10-18  Retireborn: Well if it's a Reti game I may well have seen the position before (although I have no recollection of it) which would explain why the move leapt to the eye.

Good point about 24...Bxh2; at least White managed to avoid losing the game in that way!

In those years Reti would quite often launch attacks and then mess them up; this example dismayed me recently.

Reti vs Breyer, 1916

  zanzibar: <RB> I'll have to have a look at the Breyer game later, I'm still plowing through the <Stockholm (1919) Quad> games...

(White to move after 14...Nc6-e5)

Art of the missed sacrifice?! It's sharp.

Not that it's easy to spot, but it is illustrative of exploiting a king caught in the middle of the board. No bishops, so you know there's gotta be a fork in there somewhere - just gotta set it up right.

Jun-18-18  Retireborn: Stuck on this one. I thought of 1.Qf6 Rg8 2.Qxe6, but just 1...Kd7 and White is going nowhere.

White certainly has some advantage after a centralising move like 1.Nd4 or 1.Rad1, but I don't see how a sacrifice is necessary or even possible.

  zanzibar: <RB> Well, it's not easy to spot as it starts off with some "slow-cooking". Spielmann didn't spot it, and played the 1.Qf6 move (actually 15.Qf6), and had to play another 30 moves for the win after Black did indeed answer with 1...Kd7.

Spielmann vs Rubinstein, 1919

But me & my "pal" think the move 15.Rad1 exposes all the weaknesses in Black's position without allowing time for regrouping. The X-ray along the d-file gets primed with the threat of a knight sac, Nxc7, and Black's king is too exposed.

Attacking the enemies position from the back rank, when the king is stuck in the center, is a good theme to look for.

All the top variations suggested by the engine (15...Nc8, 15...N7c6, and 15...Qd7) are fun to play over, and instructive (imo).

The actual 3rd variation after 25-ply is 15...Nf5, where Black just admits the jig is up in order to castle K-side.

Jun-18-18
Premium Chessgames Member
  zanzibar: I think the hardest line to find is where Black plays the strongest defense (which keeps the d-file closed), where White just keeps the pressure increasing till the nut cracks....

15.Rad1 Nc8 16.Nxc7+ Qxc7 17.Qf6 Nc7 18.Qg7 Rf8 19.Rf6 Ne7 20.Rdf1

And White regains the knight with Black's game in collapse.

Jun-19-18  Retireborn: LOL - I'm actually working through the quadcopter now, but am still some way short of round 11!

I think one needs to be a GM to calculate those variations you give. On the other hand, 15.Rad1 might well be played on general principles. It could serve as an example of the Seirawan phrase, "inviting everyone to the party."

  zanzibar: <<RB> Seirawan phrase, "inviting everyone to the party.">

That's a cute phrase, not sure I've seen it before.

The poor knight on c3 looks like he wasn't invited to the dance in the one variation I presented, but he does get involved in some of the other Black defenses.

You're right about this one being master (or GM) level - as I said, Spielmann himself missed it. But often I'm crimping examples from ChessTempo, and I can guarantee I'm not doing GM rated problems!

Jun-24-18
Premium Chessgames Member
  zanzibar: Not a GM-level problem, well, maybe it is, but it's from a 2200 vs 2000 player, and White found it....

(White to move after 28...Qa5-e5)

Can you guess the opening? (Probably)

Jun-25-18  Retireborn: <z> 1.Rxg6+ leaps to the eye and after 1...Kxg6 2.Rg1+ there is surely a mating attack, while 2...Kh5 loses the queen to 3.Rg5+. The Bc1 is an attacking piece!

Opening? Some sort of Sicilian, I suppose, or 1.g4 perhaps. Who knows what these 2200 Titans get up to? Not a 2100 woodpusher like me, that's for sure.

Jun-25-18
Premium Chessgames Member
  zanzibar: <RB> yes siree Bob! 1.Rg1+ to start and 3.Rg5+ to finish. Having the b7-defender as attacker makes it a little fun.

The opening was indeed a Sicilian, a Yugoslav attack...

PS- 2100 is an impressive rating, certainly from my vantage point.

  zanzibar: This is what I like to call a visualization problem, you have to see the entire combination in the mind's eye, start-to-finish, before making the first move.

(After 56...Kg6-f5)

E Hermansson vs L'Ami, 2007

It's the art of closing the deal, in other words. (It's not really that hard, but over on <CT> the problem takes blitz gun-slingers about 1.5 mins - which is on the long side)

  zanzibar: I like this one, it's a "coloring" problem:

(White to move after 27...a4)

Plus it was a bit of an upset - White being ~100 points lower rated than Black.

<Keitlinghaus, Ludger 2440 -- Rogers, Ian 2550
1-0 (31) C50i 1992
Prague CZE: Prague (1)>

Jul-18-18  Retireborn: <z> 2.Rf6 wins the bishop or smashes the black K-side. Which suggests that Black should have played 1...Rf8.

Sacrifices on an empty square always very attractive!

Jul-19-18
Premium Chessgames Member
  zanzibar: Yes, <RB> total agreement on all of that (funny how there's a sense of the aesthetic in tactics).

I like how White smashes through on the dsq's, the very ones that look protected.

From this game:

Bacrot vs Leko, 2008 (&m=31)

Jul-21-18  Retireborn: Qh7+ looks awfully tempting! Need to calculate it more carefully though.
Jul-21-18  Retireborn: Yeah, I'm happy with it, and looking at the game now I see Bacrot was too :)

  zanzibar: <RB> The challenge line given by <CT>:

Carlsen vs Anand, 2014 (&m=20)

Carlsen blitzed it out the move after.

Black missed it in the actual game, understandably, given it was blitz:

  zanzibar: White to move after 23...dxc4

An oldie, but goody. De Vere's finish to the combo was a little more flashy than needed, but effective.

<De Vere--Zukertort, London CC Handicap (1874)>

<

24.Nxc4

{ <This is one of those instances where not so much blame attaches to the loser as praise to the winner. The conception of this sacrifice is so beautiful the Herr Zukertort may be pardoned for not having seen it, while it reflects the highest credit upon Mr. De Vere's ingenuity.> }

24...bxc4 25.Bxc4+ Kh7 26.Re6 Qc5 27.Rxh6+

{ <27.Rxh6+ Splendid. Black must take the Rook with the pawn gxh6 and then White, by checking with the Bishop at 28.Bd3+ either forces the mate in two more moves or wins both Rooks.> }
