Apr-04-23		jrredfield: I went with 26 g3 but initially didn't see the full mating sequence. After spending a bit more time I chose 26 g3 Rc8 27 gxf4 Rf5 28 Qh6#. Black's 26th and 27th move don't matter much because the mate is inevitable. Black's Q is overloaded protecting the pawns on f5 and h6, either of which would be Black's doom if the White Q captured either of them. So the key is to drive the Q away.

Apr-04-23		Brenin: The Black Q has to protect her pawns on f5 and h6, otherwise the White Q captures them with mate to follow. After 26 g3 she cannot do this.

Apr-04-23		jrredfield: Deeper analysis and now I see 26 g3 Qxd2 27 Qxd5 Qc1+ 28 Rxc1 Be4 29 Qxe4 Rae8 30 Qh7#. I thought White could mate in 3 until I discovered that 28 ... Be4 could stall things at bit.

Apr-04-23		Brenin: With Black's Q paralysed, I think that 26 Nc4, threatening Nd6 and Ne5, also wins, though less directly than 26 g3.

Apr-04-23		al wazir: I think 20. Bf6 would also have won. If 20...gxf6 , then 21. Qxh6 , and mate is unstoppable. If 20...Rfd8, then 21. Bxg7 Kxg7 22. Qxh6+ Kg8 23. Qh8#. If 20...Ng6, then 21. Bxg7 Kxg7 22. Qxh6+ Kg8 23. Qh7#. If 20...Nf5, then 21. Bxg7 Nxg7 22. Qxh6 Nh5 23. Rxh5 f5 24. Qh8+, and a royal skewer looms. I don't see any other defenses,

Apr-04-23		jrredfield: I agree with <Brenin> that there are other possibilities. Black is so handcuffed with the K boxed in the corner and the Q overloaded that several White moves look like winners. g3 is the only move leading to a relatively quick mate, but Nc4, Nf1, h4, almost anything, if not a stupid move, will still keep White ahead.

Apr-04-23		geeker: After some thought, I came up with the idea to deflect the Black Q from the defense of h6. So my first candidate move was 26. g3. Black keeps control of h6 after the forced 26...Qxd2, but then f5 is unprotected and 27. Qxf5 wins. I stopped there.

Apr-04-23		agb2002: White has a knight and a pawn for a bishop. Black threatens Qxd2. The black queen protects f5 and h6. Therefore, 26.g3 Qxd2 27.Qxf5 (27.f4? Qg2#) and mate in three.

Apr-04-23		saturn2: 26.Nf1 thteatening g3 works ....Rg8 27.Qxf7 threatening Rh8

Apr-04-23		boringplayer: I went with 27.Rd1, feeling that the ending after 27...Qd1+; 28.Qd1 is winning for white. I completely missed 27.Qf5.

Apr-04-23		mel gibson: There are so many good choices that I missed the text move which is _ mate in 5. I chose 26. Nf1 which is still powerful. SF gives it over 9 points for White.

Apr-04-23		Brenin: <boringplayer>: After 27 Rd1 Rae8, with threats of 28 ... Qxd2 29 Rxd2 Re1 mate or 28 ... Re2, White's advantage is slipping away.

Apr-04-23		TheaN: Initially I came up with <26.g3 Qxd2> 27.f4?, blocking off defense of h6. Quite the blunder, as 27....Qe3+ 28.Kf1 Qe2+ 29.Qxe2+ dxe2+ 30.Kxe2 is forced, annihilating White's attack. Of course, <27.Qxf5 +-> followed soon after and it's clear.

Apr-04-23		Oxspawn: I was so fixated on finding a way to take the pawn on h6 that I did not see how 26. g3 led anywhere except losing the knight. Is there a useful oil I can pour into my ear to 'unfix' the brain?

Apr-04-23		get Reti: <TheaN> After 26.g3 Qxd2 27.f4?, black can play Qg2 mate. I almost got tricked by that same idea.

Apr-04-23		TheaN: <get Reti: <TheaN> After 26.g3 Qxd2 27.f4?, black can play Qg2 mate. I almost got tricked by that same idea.> ...can we please all pretend I did not miss a mate in one? Thanks. :/ :>

Apr-04-23		chrisowen: I ro quibble it's waft jah it's cog puzzle g3 fond cub ebb aka decider it's beg yogi g3 jalopy!

Apr-04-23		Messiah: It was surprisingly easy. When the rebellion triumphs, there will be way better daily puzzles. Victory! -- CG Liberation Front --

Apr-04-23		chrisowen: A chortle will no? x

Apr-04-23		Willber G: <al wazir: I think 20. Bf6 would also have won.> 20. Bf6 was the game move...

Apr-04-23		Halldor: I too was totally set on how to mate with Qxh6#; so g3 was the obvious move, but I thought I had to save the knight first and went for 26 Nf1 (then g3 and Qxh6). Unfortunately, I didn't see the knight sac. — Black can avoid mate in this line by sacrificing a piece and continuing in a lost position.

Apr-04-23		tibone: I think that 26. Rd1 would have won as well.
