1.Rg6+ hxg6
2.Rxg6+ Bxg6
3.Qxg6+ Kd5
4.Qxf5+ +-
Ok, I think I’ve got it.
Qh6+ (the ‘obvious’ move) doesn’t quite work, as the king can run to d5 and escape. We want the queen to be able to capture at f5 with check if the King runs to d5. So instead:
1 Rg6+ h7xg6
2 Rxg6+ Bxg6
3 Qxg6+ Kd5
4 Qxf5+ Qe5
5 Qxe5#
Rg6+ first move I examined and it seems to work
However often black captures he will eventually be forced to play Kd5 after which Qxf5+ leads to mate. Interposing the black queen on f6 or e5 doesn’t help.
I should have mentioned that after Kf7 Qxf5+ still wins
Situation desperate. Force mate or lose.
1. Rg6+ (a) hxg
2. Rxg6+ BxR
3. QxB+ Kd5 (Qf6, QxQ#)
4. Qc6#
1. … (b) Kd5
2. Qxf5+ Qe5
3. QxQ#
Mark
Rg6+ 1-0
The main line is:
1. Rg6+! hg
2. Rg6+ Bg6
3. Qg6+ Kd5
4. Qf5+ and black is lost
1. Rg6+, then after some trades on g6, taking the f5 pawn with check, unless Black moves Kf7, when Qxf5 wins quickly. Phil
1.Rg6+ fxg6
2.Rxg6+ Bxg6
3.Qxg6+ Kd5
4.Qf5#
If 3…Qf6, then
4.Qxf6+ Kd5
5.Qe5#
Well, this one was not actually all that difficult. Finding the 1st move was a bit difficult. But envisioning mate with Black king on d5 and White’s queen giving check on f5 was the key. After rejecting 1. Qxf5+ as being utterly crazy, and seeing that 1. Qh6+ didn’t work as long as White was not willing to accept a perpetual after Kf7, 2. Qh5+ Ke6 (and so on), I tried 1. Rg6+ with the double rook sacrifice in mind. That works.
1. Rg6+ hxg6
2. Rxg6+ Bxg6
3. Qxg6+ Qf6 [3… Kd5 4. Qxf5+ Qe5 5. Qxe5# ]
4. Qxf6+ Kd5
5. Qxf5#
Black can put up a more stubborn resistance with:
1. Rg6+ hxg6
2. Rxg6+ Qf6
3. Rxf6+ Ke7
4. Rf7+ Bxf7
5. Qg5+ Ke6
6. Qf6+ Kd5
7. Qxf5#
As they say in the song, “Basically, it’s as easy as pie.” 1.Rg6+ hxg6 2.Rxg6+ Bxg6 (2…Kf7 3.Qxf5+) 3.Qxg6+ Kd5 4.Qxf5+ Qe5 5.Qxe5#.
1.Rg6+ hxg6
[1…Kf7 2.Qxf5+ Qf6 3.Qxf6#]
[1…Kd5 2.Qxf5+ Qe5 3.Qxe5#]
2.Rxg6+ Bxg6 3.Qxg6+ Kd5 4.Qxf5+ Qe5 5.Qxe5#
– SS
rf6
rf6
qf6
qe5
etc
I think 1.Rg6+ wins!
What’s about:
1. Rg6+ 1. hxg6
2. Rxg6+ 2. Bxg6
3. Qxg6+ 3. Ke5
4. Qf5+ 4. Qe5
5. Qxe5 mate
Perhaps Black has to try to sacrifice his Queen in order to survive and finally have some threads with his c pawn. However I have no board or software assistance to check it perfectly I dont beleave that. White will win that game, probably by mate attack.
Mass sacrifice on g6 is the key and white mates Black king with Q checks.
1. rg6+ qf6
2. rf6+ Kd7
3. rf7+ bf7
4. qg5+ Ke6
5. qf6+ Kd5
6. qe5#
1. Rg6+ Bf6 or hg6
2. Rg6+ hg6 or Bf6 (depends on black’s first move)
3. Qg6+ wins
if Qf6 then Qf6, Kd5 then Qf5++
if Kd5 then Qf5+, Qe5 the Qe5++
Rg6+
