Dear Alain,

Your string doen't work, besides your intended solution,
there are many minor deviations like:
1.a3 a5 2.Nb1-c3 a4 3.Nc3xa4 Ra8xa4 4.Ra1-b1 Ra4xa3 5.bxa3 c6
6.Rb1xb7 c5 7.Rb7xd7 c4 8.Rd7xe7+ Qd8xe7

and also totally different games (again many of them) like:
1.h3 h5 2.Ng1-f3 h4 3.Nf3xh4 Rh8xh4 4.Rh1-g1 Rh4xh3
5.gxh3 g6 6.Rg1xg6 d6 7.Rg6xd6 e6 8. Rd6xe6+ Bc8xe6

Both example cooks show some difficulties:
The first, that 5. ... P 6. ... P without a later
promotion of that pawn usually will end in cooks.

The second, that often an intended game has a symmetrical
twin with the vertical line between d1 and e1 as the
symmetry axis.

Here is a correct string for a3:

1.P P 2.A HxP 3.AxP HxP 4.AxP HxH 5.AxH
