I found a puzzle. It was on a chessclubs website and I tried to solve it but it was hard...

Then I thought about putting it up here so that someone who can put it in to fritz could show the answer if there was any. It wasn't...

I have only put up a chess diagram there not a puzzle to solve.

My little engine shows the following line as being available;-

1 Qc6 Nc7

2 Qxc7 b3

3 Qc3#

Isn't Re5 checkmate?

Re5 isn't even check.

Yeah I get another M3 line as well (with Nb6)

1.Qc6 Nb6 2.Re5 Kxe5 3.Qf6#

Homer, what if Nb6 instead  of Nc7 ?

That takes 4 then.

so, my engine wasn't wrong?   cool.  that is a little reassuring.    thanks Homer. you aren't really as evil as they say.  (but then, what do "THEY" know anyway ?)

You're absolutely right there, bunch of know nothing know it alls!

An alternative line from my little engine for a look is

1 Nd3 Nb6

2 Qc5+ Kxd3

3 Re3#

As far as I can see it works with 1..... Nc7 too?

4. +- (#4): 1.Qc1 Nc7 2.Qf4+ Kc5 3.Nd3+ Kb5 4.Qxb4#

Isn't correct (there's a faster way to mate if Black chooses Nc7). 1.Qc1 Nc7 allows 2. Qxc7 forcing b4 3. Qc3#

you probably ment the line:

4. +- (#4): 1.Qc1 Nb6 2.Qe3+ Kc4 3.b3+ Kb5 4.Qxb6#

Are you sure you set this up right?

That looks about honours even after that sequence?

That looks about right, but is there a forced mate in 3?

• #17

you are right. the puzzle is wrong. mate in 2 not 3

yes, there is a forced mate in 3.   memory working now, I saw this one years ago.

as long as white's queen stays on the c file, black's move are completely forced.

Homer has it right.

after 1. Qc6

if                  b3  2. Qc3#

if Nb6  2. Re5    Kxe5 3. Qf6#    or     Nc4 3. Qxd5#

if Nc7  2. Qxc7 b3  3. Qc3#

and there you have it, ladies and gentlemen.

My engine is just free rather than evil, so not the strongest in the world, but hey, we got there in the end.

Nice puzzle by the way !
