I see the White d-pawn is the most likely candidate not survive a game.
Easily understood. It gets chopped in Sicilians.
In KP openings d2-d4 is ususally the only way to get an opening plus.
The Lopez, The Scotch, Giuoco Piano, The Danish, The Philodor....
d4 is usually the spark that ignites the captures and the d-pawn falls
on either d4 or e5 (after taking the Black e-pawn)
In QP openings it is the target for a freeing c5 or e5 by Black.
In the Benoni it is pulled forward to d5 and hit with e6.
In the KID/Pirc it is pulled forward to d5 and often hit with c6.
It is attacked and swopped by a c5 in The French.
I'd like to see the score of the games where the d-pawn survivs the game.
If it tips heavily in White favour then we have discovered the secret of chess.
Do not leave your d-pawn open to attack. Protect your d-pawn.
