I'd have to use a supercomputer. Can you prove that it is possible?

wait a sec.

couldn't find any ways...

I can.

To get 6 pawns on a file, we need to make a minimum of 9 captures, and this minimum is achievable only for the c,d,e or f files. Each capture needs to be made towards the file where we're assembling the pawn-row.

If we want to make a pawn-row for each player, then those captures need to consist of all the pieces (except the king) plus two pawns.

The problem here is that the rook's pawns (a and h pawns) are pretty useless:

(1) We can use at most one of them in the pawn row itself (they're too far apart to use both).

(2) We can't capture either of them when we're bulding the opposing pawn-row (because that would take the opposing pawn in the wrong direction).

So we don't have enough (non rook's) pawns - we need 6 pawns (of which at most one can be a rook's pawn) for our White pawn row and 2 (neither of which can be rook's pawns) to capture when assembling the Black pawn row.

That's a total of 7 non-rook's pawns, and we only have 6.

Yes it is legal.  Since no one got the answer, let me show you.  Remember, all i asked was how that position happened after black's 4th move.  BTW, this is just a composition.  

Very nice.

I got 5 pawns in a row, but cannot find a way to get 6.

It is possible (shown in my last comment) due the fact that White's and Black's not so usefull h and a pawns can promote! I DID IT!!!!!

ALWAYS REMEMBER  IT WAS JUHANI HALONEN WHO SHOWED YOU THIS FIRST!!!!

Congratulations! I was mistaken.

Finland. You could be the next Unto Heinonen. :)

That is awesome. Curious as to how many queens you can have on the board without it being stalemate or check.

I know the answer for the maximum by the way.

that is an interesting question. Let's see.

Is the point that only White has queens on board???

if Black's king is on e5 White could have 24 queens on the board but i'm not sure if that is the correct answer...
