And thanks for this great blog. I love the coverage of the U.S. championship.
Qa1-f6 threatening
Qxf7 checkmate and
Qxh6 check, Ne4-f6 checkmate and
(after Kf8-g8) Ng5xf7 threatening, if the Queen moves, Nf7Xh6 and Ne4-f6.
…Bf5-g6 is answered by Ng5-e6 and checkmate.
Qh8+ Ng8. And now? Nxf7 seems strong, after Kxf7 white has Rxf5+
Qf6
Too many treats for black to handle them all…
Qf6 hxg5
Qh6+ Kg8
Nf6+ Qxf6
Qxf6
I havnt done many problem’s latly but im thinking this might be an interesting line of play

I take back that! I think Nxf7 is the right move (not Qh8+ because of the black pawn at a2 is a big threat). Sacrificing the night at f7 is good because of the pin of the bishop (f5) and clearing up around the black king.
If black takes.. Kxf7 then white can play Bh5+. But is it enough for a win?

1.Qf6 (idea Qf7++ or Qh6+ Kg8 Nf6++)
Black has big material advantage, so white must be presice. My first intuition was Qh8+, but it loses. After Ng8 white has nothing. After a loong think I came up with 1. Qf6! and black is in trouble. 1. Qf6 Kg8 2.Qf7+ Kh8 3. Qf6+ Kg8 and now what? I thought perp. But wait: 4. Nf7 Queen moves and then 5. Nxh6+ Kh7 Ng5#! Therefore: Black must sac his Queen. Then it’s too messy for me. In a real game I would lose with either side 🙂

Nf6
Qf6 with duel threat of 2.Qxf7 mate or 2.Qh6+ and 3.Nf6 mate. Black is unable to counter both threats
well, strictly speaking, 1…Bg6 counters both threats, but of course this is also mated after 2. Ne6

Qh6+ …

Well, I have to admit this was too hard for me, so I submitted it to Fritz. Those who went with 1. Qf6 are correct, though I never even considered it. Anyway, according to Fritz:
1. Qf6 Kg8 (1… hxg5 2. Qh6+ Kg8 3. Nf6#) (1… Bg6 2. Ne6+ Kg8 3. Qg7#) 2.
Nxf7 Ng6 (2… Qc8 3. Nxh6+ Kh7 4. Ng5#) (2… Kh7 3. Qxh6+ Kg8 4. Qh8+ Kxf7 5.
Qh7+ Kf8 6. Ng5 a1=Q 7. Qf7#) 3. Nxd8 +-
.. not covering every possible variation, but enough to convince I think.
