Kibitzer's Corner
Jan-14-22  Brenin: White can expose his opponent's K to future harassment with 17 fxe6, e.g. 17 ... fxe6 18 Nxe6 and the e-pawn will fall, with Black's K stuck in the middle, or 17 ... exd4 18 exf7+ (this looks stronger than the materialistic 18 exd7+) Kd8 19 Nxd4, with 2P plus plenty of compensation for the sacrificed N. I can't see a forced win, but it looks worth a try.
Jan-14-22  Whitehat1963: Well, I got the gist at the beginning, but I got lost pretty quickly. And by the end, I could not begin to figure out how I would continue the assault.
Jan-14-22  mel gibson: No - I got this one wrong.
I thought:
17. Bg5 or
17. Ng5

Which are not that good.

Jan-14-22  stacase: Oh my what to do for move 18? Well I didn't see that 18.exf7+ if Black takes the Pawn, sets up double check and all the wonders such happenstances deliver.

  An Englishman: Good Evening: Saw the first four moves, which should suffice. Impressive how the attack gathers force like an avalanche starting with 12.e5. Since 10...g6 prevents Nd4-f5, should Black have played 11...e5?
Jan-14-22  paavoh: Agree with <Brenin> on how to begin, even saw exf7+ but failed to find a win. Now I see that there isn't a quick one to be found.

Jan-14-22  TheaN: Honestly, easier than yesterday IMO, but here I missed a variation, the rather straightforward KxP... weirdly enough I thought f7 was defended.

<17.fxe6> kind of screams to be played. Black is essentially 'threatening something else', and pawns this close really do become a force to be reckoned with.

Black has no easy way to decline this, as exf7+ is looming and after 17....fxe6 18.Nxe6 +- White still breaks through with an essential pawn to boot.

<17....exd4 18.exf7+> now here I missed 18....Kxf7 (and 18....Kf8 19.Bh6+ is a worse version of this) but it's obvious Black's not doing too well after 19.Ng5+ Ke8 (else Qxe7) 20.Nf7! +- threatening both Nd6+ and Nxh8. Do mind 20.Qe6? Nc5 ⩱ and miraculously Black's defending immediate onslaught.

<18....Kd8 19.Nxd4 +-> what a position.

I was confident enough White's completely dominating the board here.

Black king in the center, coordinated pieces, open files, a stinger pawn on f7. In comparison, Nb4 is a no-man's land, the other minor Black pieces are defending and the major pieces are sleeping.

SF gives 19....Nc6 20.Qe4! Na5 as best to bring pieces into defense, but now 21.Qxb7 Nxb7 22.Nc6+ picks up Be7 with the attack going. The 'logical' 19....Nc5 leads to the rather active but crazy looking 20.Bg5! Of course 20....Bxg5 21.f8Q+ +- is a no go, but Black can't really help but being overrun anyway.

Jan-14-22  KevinDenelsbeck: I got the first two moves, but went with 19 Nxd4+, which seems to be at least as good as the game text. The engine gave it pretty high marks (+10.53).

  agb2002: White is one pawn down.

Black threatens exd4 and gxf5.

White can try to expose the black king with fxe6, Nxe5 or Nxe6.

In the case of 17.Nxe5 Nxe5 18.Qxe5 0-0-0, assuming it is legal, Black seems to improve the position.

After 17.Nxe6 fxe6 18.fxe6 Nc5 19.Qxe5 0-0 20.Bh6 Bf6 the attack vanishes.

In the case of 17.fxe6 exd4 (due to the double threat exd7+ and exf7+; 17... fxe6 18.Nxe6 looks very bad for Black) 18.exf7+ (18.exd7+ Qxd7 seems to give Black the opportunity to reorganize):

A) 18... Kf8 19.Ne5 (19.Bh6+ Kxf7 20.Ng5+ Ke8)

A.1) 19... Nxe5 20.Qxe5, with the double threat Qxh8# and Bh6#, is winning.

A.2) 19... Bc5 20.Nxd7+ Kg7 (20... Qxd7 21.Bh6#) 21.Qe5#.

A.3) 19... h6 20.Nxg6+ Kg7 21.Nxe7 looks winning. For example, 21... Rf8 22.Bxh6+ Kxh6 23.Qe6+ and mate soon.

B) 18... Kxf7 19.Ng5+ Ke8 (19... Kg8 20.Qe6+ Kg7 21.Qxe7+ Kh6 22.Nf7+ Kg7 23.Ne5+ Kg8 24.Qf7#) 20.Nf7, with the double threat Nxh8 and Nd6+, must be winning.

C) 18... Kd8 19.Bg5

C.1) 19... Bxg5 20.Nxg5 (threatens 21.Ne6+ Kc8 22.f8=Q+)

C.1.a) 20... Nf8 21.Qe5 wins the rook on h8.

C.1.b) 20... Kc8 21.Ne6

C.1.b.i) 21... Nf8 22.Nf8 Rxf8 23.Qe8+ Kc7 (23... Rxe8 24.fxe8=Q+) 24.Qe7+ Kb8 (24... Kc6 25.Rf6#) 25.Qxf8+ wins decisive material.

C.1.b.ii) 21... Rf8 22.Nxf8 Nxf8 23.Qe8+ Kc7 24.Qe7+ Nd7 25.Qxb4 wins decisive material.

C.2) 19... Nf6 20.Nxd4, with the double threat Bxf6 and Ne6+, gets two pawns and attack for the knight, more than adequate compensation. For example, 20... Nh5 21.Bxe7+ Qxe7 22.Ne6+ Kd7 (22... Kc8 23.f8=Q+) 23.Rad1+ Kc6 24.Nd8+ Raxd8 25.Qxe7.

C.3) 19... Nc5 20.Rae1 Bxg5 21.Nxg5 Nd7 (21... Rf8 22.Ne6+) 22.Qe7+ and 23.Qxb4 must be winning.

Jan-14-22  landshark: As usual for a Friday I missed the best line - happily capturing the N on d7 instead of the apparently more incisive 18.exf7+

Just <maybr> if I'd been at the board doing this I'd have found the f7 capture - as it is, it's Friday, I'm finishing breakfast and off to work, and this is just a puzzle - not a pitched OTB battle that I've myself immersed myself into -

Jan-14-22  AlicesKnight: I found the fxe6 - xf7+ route, but missed the significance of Nf7 (thought Black gave the R up too easily until I saw the K/Q fork). Not spectacular but a good example of finding the best line where there are several temptations.
