the Double Whammy

I finally made a blog post for 2012!

Blog 5

Superb 😀

Hi Sg.

You will need to see if Russ can do a special PGN for doubler moves.
A pgn thingy that does not error check.

(I noticed 3 edits - it's still a bit of a nightmare to overcome the blog
posting gliches. I now post it all on my club forum to see it all works and
then paste it onto the blog. Even then mistakes filter through, you cannot see
the notes from some PGN's till after it's posted. But it's all good fun.)

HI Sg

PM sent just on the double Whammies.
The one that took your mate 30 mins I got fairly quickly

This one...


.....took me while though.
White to play and mate with two move on the trot.
(White makes a move and another and it's mate - Black does not move at all).

Don't post solution (even hidden) PM SG when you have them all solved.

Heh, I just got that one and the 13x'er myself. Not that I would post problems without knowing the solution. 😛

(Your double whammy solutions were correct.)

The 109x whammy was just too long for me to even attempt.

Typical SG the rat. His first blog of the year and we get 'Mate in 109 moves.' 🙁

I've solved the whammy in 13 if the board is flipped.
I can do it in 6 moves!

(ignore the Knight going back and forth from a6-b8 he is the
PGN 'fooler' to give White all those moves on the trot.)



Here is the original mate in 13 whammy.


I'll solve it at work tonight.

The 109 one I can do in 8 moves if I flip the board.
I'm good at doing things upside down.
I think if chess was played upside down I'd be world champion...perhaps.



Here is the original series mate in 109 whammy.

[FEN "7K/4P1P1/n7/8/8/8/1b6/k7 w - - 0 1"]
1. e8=N Nb8 2. ...[text shortened]... te in 109 whammy.

I gave the first 80 moves to the 109x, and left a strong hint about the last 29. It's not that hard - really!

You would probably have liked wild-5, a variant played on the old US Chess Live server. The starting position was:



It's not a mistake in the FEN - all the pawns are one move from promotion. It's a mad scramble to get the big pieces out of the way and promote pawns. Naturally, all the games begin with two N moves. 🙂

About your other 4 solutions - watch out for pinned pieces, pieces blocking checks, and protected pieces.

OOPS wrong post in wrong thread - move on. Sorry.

I got them all in the end, though one was "too easy" and I overlooked that I had created one issue by solving another. It only took a second to fix it after SG had kindly pointed it out!

I found the "30min two mover" the hardest of them all - and actually the most insightful for normal play...!

That's true, it's a good lesson.

Well, at least if my second try on that one is correct.

The following are my solutions, but they are wrong. So do not make the same mistakes I did.

2x whammy - Rg7, Qf8 mate
2x whammy - Qb5, Qe5 mate
13x whammy - d4,d5,d6,d7,d8(Bishop),b4,b5,b6,b7,b8(Queen),Qb7,Bf6,Qxg7 mate
2x whammy - Qd4, Qxd7 mate

I had the misunderstanding that the 109x whammy required 109 moves and did not feel like making 109 moves to solve it. I apparently had a misunderstanding on the other whammys too.

Can you see what is wrong with them?
