I'm coming to the conclusion that the opening is the part of correspondence chess where humans have the most influence. If most games are played by centaurs of one kind or another, being able to "trick" an opponent who overestimates an opening position is one way to make some progress, especially as Black (where I seem to be getting the bulk of my wins at the moment—in the Caro, which in general I think engines don't handle particularly well).

Generally, I think Stockfish usually overestimates White's position in the early opening, especially with an early space advantage it goes up around +0.8 or more. On the other hand, sometimes the others may get 'too dynamic'.

One way to get an estimate is to pit the three big ones against each other, and perhaps add one's favourite Stockfish clone too, and see how the games go both move wise and result wise. Often they meet half-way, with one engine decreasing and another increasing White's/Black's advantage.

I'm curious about chess openings that chess engines tend to underestimate due to some kind of positional concession that—in the long run—tends not to be quite so decisive. For example, Stockfish hates the Bronstein-Larsen variation of the Caro-Kann. After 5...gxf6, it gives White almost +1.00. After considerable analysis, I don't doubt that the line is a little dubious, but by move 10-15, Stockfish's evaluation has dropped to ~+0.50 in most variations (which sounds about right). Are there other openings (for White or Black) that trip up engines in a similar way?
