Apologies

You don't need to apologize. You didn't do anything wrong.

It's an obvious win for green.

From starting position, it is win for white.

Looks like a draw to me and Stockfish 6 on my machine scores the starting position dead even at depth 45.

Even though I agree it's clear drawn, and have been saying so, it's impressive that Stockfish 6 says so.

I left Stockfish 5 running on 8 cores for the last 5 hours and it still says +1.08 for White (six lines tied) although none of them actually end in a win.

To anyone who cares...I got round to installing Stockfish 6 (BMI2 version).  It finds this position as drawn in about 30 seconds or so.  Stockfish 5, as noted above, does not realize this after 5 hours.

For the record, Stockfish doesn't have the evaluation at +1 as the OP claimed. Stockfish has the evaluation after b6 as +.81. That means that White has an advantage of nearly a pawn, but it's not a winning advantage. 

I'm sure most of us will agree that is a correct evaluation of the position.

Well...that is going to depend on exact version of Stockfish, exact processor, exact running time, etc.  For me, Stockfish 5 (64 bit modern compile) showed 1.08 after several hours.  Stockfish 6 (64 bit BMI2 compile) shows a similar number for about 30 seconds and then 0.00 after 30 seconds.

Also, White has in fact no advantage at all.  No pawn can be force through unless Black makes a mistake.

What depth was that?

I reran it and this is the depth:

Assessments in order:

Depth 30ish (went by too fast to really see) was 1.09.

Depth 40ish (went by pretty fast) was 1.00.

Depth 43/48 (not sure what the two numbers mean) was .56.

Depth 44 and thereafter was 0.0.  It's never going to change back.

More important, you should be able to see for yourself that there is no way for the White king to get in.  The Black king can block him forever.

Actually, you are rated 2200 at standard...you MUST see this!

You're missing my point. I'm not arguing that the position's won, I'm arguing that Stockfish got it right: White has an extra pawn, but it's a draw.
