The crucial part of white came from 25th Re3...which was unclear...best should be 25. Rxc4, which could have gained the dangerous c-pawn by black and head for a pawn advantage heavy piece endgame.
The final position we see Q vs. 2Rs is very difficult for white to win...at this point black's Rd7 consolidates the defense...it is very difficult to create any breakthroughs.
We have to give credit to Akobian's stiff resistance...he played resourcefully after Wesly's 25.Re3 in time trouble...
