White to move. How should White proceed?
Level of difficulty: 2.5
Perpetual checks?
“Wednesday afternoon chess tactic”
Here in Germany it is wednesday since some minutes but it isn’t afternoon at all. Perhaps we should check our calendars, Susan. 😉
Nice exercise by the way, if I haven’t overseen anything the win is forced without any sacrifice this time.
1. Qf6 wins.
After Rhg8 (Rcg8 is worse) 2. Ree7 gives black the possibility for one last check (Qd1+) but after 3. Kg2 it is almost over.
Last try: Qd4 to defend g7 through the whit queen but of course
4. Rxg7+, Rxg7 5. Rxg7+ and 6. Qh6#
Greetings

1.Qf6
and if 1..Rh(c)g8 then 2.Ree7
and Black has only one check on d1, then he can resign.
Qf7 Rg8
Re6 Qxe6
Qxe6
i cant see anything but this trying to force the mate on g7. i was thinking maybe sac the rook with Rxg7 but it seems to lead to nowhere.
1. rxg7 is interesting.
1. … kxg7
2. qe5+.
now, white tries to get the q out on a different file so the rook can come in.
so, if 2… kf7
3. qd5+
now, white plays everything except re6+ because then, black has …qxe6.
if 3… kf6 or 3…kf8, white has a q-check on d6 followed by re7+ or re5+. (or if k moves to g8, then qg6+, kf8, qf6+, kg8, re7 and mate).
other moves for black on move 2 will txpose to one of these scenarios.
I like the new rating system Susan (2.5!) … minor suggestion: 2.5/4 would give newcomers a hint about the scale.
I can’t find it!! For the first time in my blogger life I can’t find it! Came here to see the solution.
“2.5/4” Well, you’d expect a trainer to know this scale stuff. It’s ok, plenty of time to learn.
How can white win after 1 Qf6 Qd4!?
by giving mate in one move
Chris moves
1 Qf6 Qd4!?
then
2 Rxg7+ mate
I missed this one. However I found another winning line:
1. Rxg7 Kxg7
2. Qe7+ Kg8 (2..Kg6 3. Re6+ +-)
3. Re6
[with the idea of 4. Rg6+ ]
3.. Qf5
4. Rf6 Qb1+
5. Kg2 and Black has run out of checks and he cannot stop the mating net of Queen and Rook. i.e. Qf7 and Rh6
However my solution is not right because Black can sac his queen for a rook and go for an ending of 2 rooks vs. Queen where it is unclear who wins or a draw. i.e. 3..Qxe6
So I am concluding that Jochen’s solution of 1. Qf6 is the only clear-cut solution.
