Havel's Helpmates

You might regard this as a sequel to last week's Unexpected and call it "Unexpected 2". But these blog posts are not intended to be like the Die Hard movies ... Moreover, I like the alliteratve title. ;-)

Anyway, I was quite astonished to see that Miroslav Havel composed quite a bunch of helpmates, some very nice onces, as well. So, this week, I concentrate on this area and hope you like what I chose for you.

The first one is rather a joke problem and could be presented on April Fools' Day or New Year's Eve. No. 3 makes good use of the available space and surely comes up with a little surprise, doesn't it? I like the twins of No. 5, you too? No. 6 is really curious, though I don't really understand the sense of so many phases — just to accumulate as many as possible?!
