26. Rhd1 seems like an inaccuracy. Rad1 would allow the other rook to come to f1 on your 32nd move, but Black's pressure is still plentiful in any event. 24. Nd3 also seems incorrect. Again, Rad1 draws more appeal to me.
On another note, why did Black play 43...Rxc5 right away? ...Rxg2 seems to offer Black good winning chances since the h-pawn is also unsalvagable. Nice job snagging a draw from a 2150 though!
Any comments or suggestions are welcome.
