Re: Why is this position evaluated so?
With a big advantage due to the bishop pair and superior piece coordination" [for White]
Why is the coordination superior? What coordination?

Why is Black's piece coordination said to be superior?

Re: Why is this position evaluated so?
You know what coordination means, yes? Its obvious in the position above. Rather less so in the bishop pair one.

Re: Why is this position evaluated so?
It generally means that they're coordinated with each other. So they can defend each other, attack as a fairly unified group etc.
In the position in question the immediate issue is white's knight on c3 - its bang in the way of the e1 bishop and the rook/queen on c1 and c2. Even if you move it somewhere though, then the bishop strongly 'wants' to come to c3 and what are the rook and queen doing on c1 and c2?
(Also, less seriously, the f3 bishop is rather cut off from its friends.).
Its very hard to make coherent sense out of it all.
In contrast all black needs to do is to move his e6 knight towards d3 (yikes!), or just shunt the e8 rook rover to d8 and everything is doing something useful.

Why does the author say that the e6-pawn is weak?

Re: Why is this position evaluated so?
Here, the author says ......g5 would weaken Black's position, why?
Is it a general fact the advancing pawns weakens them in an endgame?

Sometimes g5 not so weak by itself here, but imagine white going hg, Ne2, Nd4, Nf5......

Re: Why is this position evaluated so?
Bad things for black in that initial position, I suspect. Shipov's mammoth hedgehog books are very clear about how strong that sacrifice can be, and that's when it loses a piece!
Not really an evaluation question though, you'd have to work out the concrete consequences. Computers are quite handy for this of course
That later position, well, black position is just a bit pointless. The e4 point has survived, and black is out of shots to fire at it. Nice illustration of why black has to break it down earlier actually, or at least get h5,h4,h3/g5,g4 in to soften the long diagonal. Not sure how slight the advantage is in practice for humans, not so nice to play black there.
