Endgame problems...

Today I playied a match vs a 1470 rating, you can see the match here http://www.chess.com/livechess/game?id=689864508 .

My problem is that i'm decent in opening, good in middlegame (for my level of course... that i think is about 1300 elo), but i'm a total disaster in the endgame, in this match i went into an endgame won theoretically, but i losed it badly, now i'm studying silman's endgame complete course, it's good enough for it? How can i improve in the endgame?

Thanks to all!

Silmans endgame course is alright but it does not cover the whole endgame theory. It doesnt even cover 2 rooks vs 2 bishop and rook endgame.

Franci the thing i see wrong with the endgame and even though im no expert its pretty clear you couldve had the advantage by putting your king in the middle. Your opponents pieces seem inactive

I never get tired of recommending Chris Ward's "Starting Out: Rook Endgames". It is an excelent book.
