  perfidious: Shah notes that:

<17...b4 looked more natural, although after 18.Nd5 Nxd5 19.Bxd5 Bxd5 20.Rxd5} White is clearly better.>

This seems unpleasant to play with the hole on d5 and poor long-term prospects, but perhaps offered more chances than the way the game actually went, which proved a showcase for White's tactical virtuosity.

Mar-06-16  Andrew Chapman: What's wrong with 15..dxc5 getting rid of the backward pawn?
Sep-22-17  Altairvega: 23.Rc6 Qc6 24 Bf7+ Kf7 25Qh5+ Kg8 26 g6
threatening Qh7+ This line I saw. Let us see what happened in the game
Sep-22-17  diagonalley: wow... that was impressive
Sep-22-17  Walter Glattke: 25.-g6 26.Bxf7+ Kh8 (Kxf7 Nh6++ Kg7 Qf7+ Kh8 Qg8#) 27.Qh3 Nc5 28.Bxg6 Qd7 29.Nd5 Nxe4 30.Nf6 Nxg5 31.Qh5 Qb7 32.Qxg5 hxg6 33.Qh4+ mating
Sep-22-17  NBZ: Hmm so I had Rxc6 Qxc6 Nf5 Be7 and then Qh5 (instead of Qf3). The idea is that if g6 Bxf7+ Kxf7 (Kh8 Bxg6) Qxh7+ and Qxg6 wins. And if Black plays Kh8, this is even better then in the game, no, because White hasn't lost a tempo by playing Qe2-f3 and then Qf3-h5.
Sep-22-17  WorstPlayerEver: 23. Rc6 Qc6 24. Qh5 Kh8 25. Qf7 Bg5 26. Nf5 Bf6 27. Rd6 Qc5 28. Rf6 Qf8 29. Qf8 Rf8 30. Rc6 and White has a big advantage.
Sep-22-17  Clement Fraud: Oh dear, I guess that I form part of this site's "weaker Kibitz brethren": I saw 23.Rc6 readily enough, but I was thinking more in terms of preventing black's QP from blockading on d5, plus white's attack on f7 (eg 24.Bd5 & 25.Qf3). In short, I completely missed all of Fedoseev's brilliant tactics (must try harder next time).

  MKD: What is the continuation if Black plays 22....Ne4?
Sep-22-17  Cheapo by the Dozen: I switched the first two moves, and in all lines I saw White at least got a little material advantage while maintaining an attack. Lots of horse dancing.

23 Nf5 Bxg5 (... Bf8 simply loses a a pawn, along with its other failings)

24 Rxc6 Qxc6

25 Qg4 Bf6 (defending the hanging bishop let White take it and then fork at e7)

26 Nh6+ Kf8

27 Nxf7 forking rook and d-pawn

Sep-22-17  paavoh: Like a knife through butter. Fedoseev's games are not boring.

  patzer2: For today's Friday puzzle (23. ?) it seemed obvious that White needed to play 23. Rxc6! to get rid of his awkwardly placed Rook and eliminate one of Black's strongest defenders (i.e. the light square Bishop.)

After 23. Rxc6! Qxc6, I should have seen Fedoseev's strong follow-up 24. Nf5! +- (+5.79 @ 30 depth, Stockfish 8.)

Instead, I chose a weaker, but still winning initial follow-up move, with 24. Ncd5 +- (+3.23 @ 35 depth, Stockfish 8.) Fedoseev's stronger 24. Nf5! is preferable, for both tactical and positional considerations, because it doesn't obstruct the Bishop's attack on f7.

P.S.: For a Black improvement, the idea of not obstructing your own pieces also comes into play. In the opening, instead of 9...Nbd7 which temporarily locks in the Bishop on c8, the computers and the vast majority of masters prefer the popular move 9...Be6 = as indicated at Opening Explorer.

Sep-22-17  WorstPlayerEver: Checked the line 23. Rc6 Qc6 24. Nf5 but then the line 24... Bg5 seems very enginish.

  gofer: Wow! This is a fruitful position, so many threats, so many options, so many attacking lines. <CG> have definitely upped their game this week.

Rxc6, Rxd6, g6 Nf5, Ncd5/Ned5, Qh5, Qf3 and even the calm h4 should probably get a mention. But unless we make this POTD simpler we are never going to get anywhere, so which lines are most forcing? Probably, Nf5 or Rxd6 or Rxc6.

Doh! Still three to look at in detail, but for some reason I am drawn to Nf5 more than anything else. There are definite chances of setting up a <Windmill of Destruction> and also possible sacrifices on h6 too allowing Kh1/Rg1+. But <23 Nf5 Nc5> looks to reconnect a lot of black's defences, so perhaps it is better to deflect the queen first, so that Nc5 is not a reply for Nf5...

<23 Rxc6 Qxc6>
<24 Nf5 ...>

White lines up the rather "blunt" threat of Nxe7+ not only winning the bishop, but also the queen too. So the threat is a "real" threat bute it is highly unlikely to ever come off. What it really achieves is launches Ne3 into the action without loss of tempo AND brings another friend to Pg6. Qe2 is joining next move and the three of (with the help of the overwatch from b3) will rip black's world apart...

24 ... Kf8?
25 Qh5 mating

24 ... Bxg5?
25 Qh5 Bf6 (h6 Qxf7+ Kh8 Qxg7# or g6 26 Qxg5 +-)

26 Qxf7+ Kh8
27 Rxd6 +- (white will remove Bf6 take Qc3)

24 ... Re8
25 Qh5! g6
26 Bxf7+ Kxf7 (Kh8 27 Bxg6! Nf8 Bxh7 Nxh7 +-)
27 Qxh2+ Ke6
28 Ng7+! Kf7
29 Nh6+ Ke6
30 Qxg6+ Nf6/Bf6
31 gxf6 Bxf6/Nxf6
32 Nxf6 any move
33 Ncd5+ +-

<24 ... Bf8>
<25 Qh5! g6>
<26 Bxf7+ ...>

The bishop is immune!

26 ... Kxf7
27 Qxh7+ ...

27 ... Ke6 28 Qg8#
27 ... Ke8 28 Qxg6#
27 ... Bg7 28 Qxg7+ mating next move

<26 ... Kh8>
<27 Bxg6! h6>
<28 Nxh6 mating>

~~~

Okay, I got it, but I have no idea why white played Qf3, when Qh5 was on offer! But then I only do this as a hobby...

  gofer: Ah, I think I have found the fly in the ointment for why 25 Qh5 is premature!

23 Rxc6 Qxc6
24 Nf5 Bf8
25 Qh5 d5!

It looks like black can now survive by playing Qg6, but I think the end game is lost for black...

26 Bxd5 Qg6
27 Qxg6 hxg6
28 Bxa8 Rxa8
29 Rxd7 gxf5
39 exf5 +-

White is a pawn up with a better position.

Sep-22-17  WorstPlayerEver: Yeah well, from here it looks easy. I found 23. Rc6 Qc6 24. Qh5 a tempo, but if you need a win behind the board to win some prestigious tournament... it's gonna be a totally different case.

Trust meh 😊

Sep-22-17  Cheapo by the Dozen: Move 28 would also be a nice Monday puzzle.
Sep-22-17  WorstPlayerEver: PS

So recently proved that the exchange sac is somewhat harder to play when you need a win behind the board; facing a strong opponent to win something prestigious, than when you make a move coming from your comfort zone.

Well... I hope. That is. As it comes to the latter.

  kevin86: The key was the beginning of an attack of f7. The queen will mate soonest!
