This endgame can come out of the scotch gamibt, albeit there are better lines for a black player that desires a draw. However, I was wondering out of curiosity if this is good for white or black.
Komodo 9.3 evaluates the position after 1.Kd5 (after searching to 31 ply) as +2.32 for White. Playing out a few lines, White usually ended up with Q+2P vs Q+P. It's not necessarily winning (Q+P endings have lots of resources for the defender due to all the checks) but I am comfortable asserting that the position is more pleasant for White.
For what it's worth, the position has occurred 6 times in my database, with 4 White wins and 2 draws.
There are many variations here which all lead to a win for white. The pawn on c4 is the only piece making a difference. After 1. Kd5 Kf5, you just push on the queenside and eventually Black has to make a concession. White also wins the pawn race after 1. Kd5 Ke3 because of the advanced pawn.
