If you are strong at endgames, which openings are favorouble for you because they tend to lead quickly to an endgame ?
The Berlin comes to mind.
White can avoid this famous endgame, but only at the cost of relinquishing any prospects for an opening advantage.
Generally I have a hard time coming up with openings leading to endgames. There are rather variations within openings that are endgame prone.
To find variations like the Berlin I advice you to look at the games of Ulf Andersson. He is famous for going into the endgame as quickly as possible.
