Searched previous breads, but didn't see…sorry if hogging a slice -
I'm sure that the D5 chess analysis has been thorough, but I haven't seen this yet:
An opener of D4, D5 is called a Queen's (HRC) Gambit. ( a gambit is not just a gamble. Strictly speaking, its something done with the aim of gaining an advantage, especially at the outset of a discussion or disagreement. It originally referred to a chess move in which a player deliberately sacrifices a piece for the great good of winning the game.)
Ironically enough, it is also known as the Aleppo (Syria) Gambit.
Sounds like it applies here.
