is this a draw for white? any idea how white should continue ?

Yes. In the final position, White should be able to hold the draw against anyone. But Black had a winning position earlier, when he was two pawns up. But rook endgames are tricky!
In the game 52.Rxc2 was a very clever! If Black grabs the "free" rook with 52...Rxc2, it's stalemate. I might have missed that myself

53. Rc5+ draws easily. The Black K has to back up, and then 54. Rc4 picks up the pawn.
I agree with @Laskersnephew that 52. Rxc2 was a clever move. Kudos for finding it over the board. Many players would have missed it.

53. Rc5+ Black King doesnt have to move, Rook can also block. After that?
White trades rooks with 54. Rxd5 Kxd5, and the pawn endgame is a draw. Of course, white can lose it if he plays bad moves, but correct defense is easy if you know it.

53. Rc5+ Black King doesnt have to move, Rook can also block. After that?
Good point that I should have addressed. If the Black R blocks the check, White exchanges Rs and the K+P ending is a dead draw.

Every position is diff. but winning these rook endings, can often be based on whether or not U can cut the king off or not/ when the defender can get the king over, it is usually a draw.

Seriously, this is your contribution to this topic? Do you think that this is good enough? Especially after posts 3 and 4?

every ending is different/ some players can benefit from general advice, including myself in my younger years. / and I will post in whatever topic i feel like unless a chess.com/mod sends me a message telling me something different, thank u very much...
