Au contraire.
Carlsen losing?

It must be a nightmare getting an even endgame against Magnus.

Difficult to pick black's next move (81), and he doesn't have much time.

Can someone explain move 50 where Carlsen sacrificed his rook?
Well, he's either losing the exchange or his bishop.
Doesn't sac the piece, the check is just an intermezzo.

Can someone explain move 50 where Carlsen sacrificed his rook?
If he moves the Rook, he loses the Bishop on d5.

Why on move 50 couldn't Carlsen play Rcxc5 and win a pawn? Is the position after 50. Rcxc5 Bxc5 51. Nxd4 Rxd4 a clear draw or something.
Looks like Karjakin's kicking his behind.......
