But wouldn't 4. exf7 be exf7+, requiring Kxf? How about:*Originally posted by leisurelysloth***is it something like**

1.e4 a5

2.e5 Nc6

3.e6 Nb8

4.exf7 Nc6

5.fxg8=B Nb8

6.Ba6 bxa6

7.Bc4 Nc6

8.Bf1 Nb8

1. e4 a5

2. e5 f6

3. exf Kf7

4. Ba6 Kg6

5. f7 bxB

6. fxN=B Kf6

7. Bc4 Kf7 puts K into check! Arg!

8. Bf1 Ke8

I can do it a couple of different ways in 9 moves, but not in 8! - 30 Jun '06 18:13

The problem was composed by Joost de Heer and used in the Messigny 2006 solving tournament.*Originally posted by David Tebb***Excellent problem, BigDogg. Who composed it and where did you find it?**

Please post a few more like that.

I'll put a couple more problems from that event up in seperate threads. - 02 Jul '06 19:40This beautiful problem reminds me of a book by Raymond Smullyan, "The chess mysteries of Sherlock Holmes". I haven't seen it mentioned before on RHP. In it the great detective solves several mysteries using what he calls "retrograde analysis". Here's a fairly easy example:

"As you see, Watson, neither side is mated-not even in check. And we are given that your side is White. The question now is this: Given that Black moved last, what was his last move, and White's last move?"

Even Watson gets it fairly quickly. Other problems are trickier.
