I assume you are speaking about tripling rule. I.e., if you have 100$ riding, you can double down for another 100, and after that, if you still want another card, you can add an extra 100$ to make the total bet of 300$. Did I get it right?

And most likely you are mistaken with the surrender rule - I have never ever seen a late surrender in combination with European rules. Most likely it is ES10 game.
