That's funny, Goran.

Can you do it one lign up  ? (that is h7-h5 comes after g5-g4, itself
coming after f7-f5, etc... (or in the other side, or with whites)).

Even harder, one can ask to construct L2-L5 or L7-L4 in order.

In that setting, "order"  meens either :

- "Light version" (in the case L2-L5, the moves a4-a5, b4-b5, etc... come
in order or inverse order, but no order are required for a2-a4, b2-b4,
etc...).


- "Heavy version" (in the case L2-L5, the moves a4-a5, b4-b5, etc... come
in order or inverse order, AND the moves a2-a4, b2-b4, etc... come also in
order or inverse order).


At first glance, it seems to me that L-v might not be too hard to achieve,
but that H-v is like a task...

But perhaps are these problems already solved. Joost will certainly tell us...
