Looking to identify Solitaire game
The closest I’ve found is Batsford.

Batsford uses 2 decks, and has 10 tableau stacks going from 1 to 10. You didn’t mention how many foundation piles; but given 2 deck I would assume 8 foundation piles. 

The problem is that Batsford only has the top card facing up in the tableau stacks. Perhaps this is a Batsford variant that alternates the cards face up and face down in the tableau stacks...
