49.h4 looks like a draw
Queen's Gambit Declined to the Endgame, please advise

On your part twice you were too intent on trading Queens giving yourself a doubled pawn. The first time he did not bite. Also you lost the pawn as you forgot the rules? On his part he played the endgame poorly. There is no way he should have lost that game. Rooks belong behind passed pawns no matter who has them. This was an easy draw.

Merci, Monsieur "Hic et Nunc" (here and now), and my old friend Chess2K for your helpful commentary.
Please advise me whether you think that white in "no way . . . should have lost" meant that it should have been a draw, or that you think, with fairly average play on both sides that white should have won.
Once again, thank you for taking the time to comment.
Cheers,

Concerning the move 49. h4, I ran the resulting position through a post-game analysis and found that Black has a relatively easy forced win. I am going to post the .pgn below.
Is this accurate?
Cheers, Becky

Who said anything about a "Gabmit"? I think you have the wrong party. Oh yeah, whoops. I'll change it. Thanks.
Cheers,

To answer your questions I believe the position is drawn, not a win for white. I also believe 49) h4 is too late for white. Analysis above looks accurate. There was however a draw for white earlier where the rook is not sacrificed that early. Black also must be careful not to let the pawns get too far advanced or supported by their king when white sacs his rook for the last black pawn. Best play should yield a draw earlier on.
This is a recent game I played in the QGD, can anyone pick up on moves that should have been played better on either side, missed tactics, or faulty strategies, or poor endgame technique? Thank you.
