New evidence proves Black wins with best play on both sides!?
Is this a draw? What if the Black pawn on f7 is on g7 instead?

Not if you move the f7 pawn one file to the right, but then neither is it the starting position.
A symmetric position like the starting position is either a draw or a zugzwang or zwang (first player wins). This is not true of positions in general, so the asymmetric "starting" positions are not as relevant to the question.

There are 180 pages in this thread. No one has offered the game that Ponz requested as refutation in his first several posts.
In the meantime, other questions have been posed.
Since there is currently a solution for every 6 (or maybe 7) piece game of chess do you know if every "starting" 6 piece game is a draw? For example both sides have king, pawn, and bishop in their original positions.
My post addresses these.
PATRIOT If both sides start with king, pawn, and bishop in their original position--it certainly is a draw..
And of course every starting position of 6 or 7 pieces is Not a draw. For example White could have a lone king and Black could have K and 4 queens [assuming no instant stalemate] and then Black would have an easy win.
@Ziryab
Yes, you're right, my apologies.
I think probably the symmetry of the starting position across the board is connected with the idea that the starting position is drawn, so I would count these as more relevant indicators of the situation for the full starting position
If, for example, the fraction of winning symmetric partial starting positions began to look like
1-ℯ⁻ⁿ as a function of the number n of pieces this might convert some people to the idea that the initial position is actually won for one side or other. Unfortunately we currently only have relevant EGTBs for 2, 4 and 6 men which is a bit underwhelming. A fraction of 0 for the two man position is obviously a good start.

Eight pieces. Known outcome. Gioachino Greco knew the outcome in the early seventeenth century, but there were errors in his analysis. Jozsef Szen worked out the key ideas in the 1830s. See http://chessskill.blogspot.com/2020/06/three-pawns-problem.html
i just googled 'shannon's number' and i got...360.479.5104

This is more what I was wondering about. If I understand this right if one side is to move first it's a win, if the other moves first it's a draw. But if it's the Szen position then either side moving first is a win.
I realize a starting position like 2 rooks and a king in their original positions is very easy, but I was wondering if positions similar to the Szen have a first move advantage that results in a forced win. It seem like there are probably some positions where it's not so obvious and some could be forced wins and some are forced draws.
PATRIOT I already showed that Black wins from the starting position. Have found one game i n trillions of games played where Black forces a win from the starting position. [then I found more]
You were right all along--there were so many draws at the higher levels because players who had Black had believed in the Fake News that they had a disadvantage and could only play for a draw. Once I realized Black wins with perfect play I was winning game after game with experts and masters and grand masters with Black.

Follow the link, and maybe another link from the article to see Szen's position. In the position that I posted this morning, both king's are in the starting position. In Szen's, the kings are both equidistant from their own pawns. In Szen's, the player on move wins with perfect play.
we know that the player who moves first CAN and does lose in certain conditions at its most basic level, right ? K+p vs K (opposition). this proves that at least a real sample does exist.

But that isn't with equal material (and obviously can work only if Black moves first). With KPKP and all pieces in their starting positions all positions are drawn.
Can you think of any symmetrical position with the pieces (what pieces there are) in their starting position that is won by the second player? (If you post the FIDE starting position you'll need to prove it.)
Many players already have played a perfect game where no mistakes were made. These are often short games where a draw is agreed to early.
1. e4 e5 2. Nf3 Nf6 agreed drawn
Actually there have already been thousands of perfect games played.
If the game is short you do not need a super computer to tell if the game is a perfect game.
You already assume that ending position is drawn...
PROMETHEUS That is a post from long ago.
But yes, I assume the ending position mentioned i a draw when neither side makes an error.
My assumption is made from a ton of evidence
PS I have even more evidence now than when I made that post.
3523 etc are irrelevant since they can't be forced into.
What I was saying is that if either of those diagrams replaced the diagram in FIDE Art. 2.3 your argument couldn't be correct, because both are demonstrably won for White with best play. Therefore your argument is either invalid or makes some (unstated) assumption which is true of the standard starting position but not of the positions in posts #3523 and #3532.
If the latter, what would that assumption be? Would it apply equally to all FRC positions?
The positions can't be forced from the starting point.
That in itself could take some proving, but how is it relevant?
If either of them were the starting point your argument would appear to prove that they're drawn which is false. This means that your argument is invalid or missing some unstated assumption which distinguishes them from the standard starting position.
Do you concede that your argument is invalid? If not, what is it that makes the argument work for the standard starting position but not those in the posts quoted?
You could evaluate other arguments you have advanced under the same criterion.

The quoted positions can't be forced from the starting point of all the pieces and pawns on home squares and therefore the introduction of this argument is spurious and irrelevant. If you think the positions can be forced from the starting point then it's up to you to prove it, because of course, then, you would have succeeded in proving that chess is a forced win.
<<<You could evaluate other arguments you have advanced under the same criterion.>>>
I'm sorry, I didn't follow. What criterion is that?
I haven't the slightest idea whether the positions can be forced from diagram in FIDE Art. 2.3 As I already said it's not relevant (in any colour).
The criterion (in any sized text of whatever colour) is that if your argument (comprehensible to others or not) purports to prove that chess (basic or competition rules) is a draw from the diagram in FIDE Art. 2.3 but doesn't include any property of that position that distinguishes it from demonstrably won positions for one side (under the corresponding set of rules) it is necessarily invalid or incomplete.
If you don't follow that, well, it's just a shame.
