DaveSun wins Chess challenge 29

1.Rh8+ Kxh8
2.Qh6+ Kg8
3.Qxg7++


Chess challenge 30

Black to move and mate in 3




Well done, Dave!!!

I just had a quick look-over at No. 30, so this may well be wrong. But here's my solution, fwiw. :]]


1. Bg2-h1+; Qd1-f3 (forced)
2. Bh1xQf3; White whatever: it doesn't matter.
3. Qh3-g2++

Sorry Beethoven, but your first move isn't a check, and King would take Bishop at no cost. The rest of the the play was generally good though ;)

Just to let you all know, there are two variations of a 3 play win for black here :)


Hi Ice!!! :]]

Nah, the King can't take the Bishop. Because then Black checkmates him with 2. Qh3-g2++ <winks>

It's true that my first move isn't a check...but you only need a steady stream of checks when the other side can check you back to throw off your "mates in" count. If you look closely, White doesn't have that opportunity here. :]]

Sorry Beethoven, I'm still thinking about the last bit

Chess challenge 30

Black to move and mate in 3




My first use of chess notation.... and I'm pretty useless at chess myself but would this work (sorry about my appalling notation!)

1. Bg2-d5 Re5-d5x
2. Qh3-g2++


Best Regards,
Luke.

Yes, this will certainly work Luke, and an excellent try from you.
However, to thwart your check mate in 2, white queen will move to f1, rather than take the bishop on d5, to stop any check mate by black queen to g2, and to stop any chance of check mate within 3 moves. Thanks for your try :)

Ahhh! But it's also a fine start to a mate in 3! :]]

How about this?


1.Bg2-d5; Qd1-f1
2.Qh3xpg3+; pf2xQf3 forced (if Qf1-g2, Qg3XQg2++)
3.Nf4-h3++

You're both getting close now :)
But your second variation here doesn't count Beethoven since Qf1-g2 is not forced and white is not forced to give away a check mate in 2.
In your first variation, can't white queen take the horse and get out of your check (mate)? ;)

I don't know, it was too long ago. LOL I'll have a look at that and at this variation later. :]]

Have a good afternoon, everyone!

Okay, I had a look. :]]

In my first variation, no white never gets a chance to take the Knight, because then Qh3-g2++ checkmate immediately.

Now this second variant is a tough nut to crack.

Here's the best I can do: a mate in 4.


1. Bg2-f3; Qd1-f1
2. Be7xc5; RxB
3. Nf4-e2+; Qd1xNe2 (forced)
4. Qh3-g2++


I also see a discovered check variant, but that's also mate in 4.


So, show me what you had in mind. :]]

You picked the right time, Ice. Currently 7:30 AM here, I have the next 5 days off, 4 Day weekend (Thursday right now) and today off, I decided to stay up all night wandering the internet, went to check the SETI boards, no change, got breakfast, came back and answered the problem....
