Critical Position
The position is tense. Black has just attacked the queen with 36…Nd4. Black has a menacing looking queen and …Rc2 targeting h2 is in the air. White has a strong Nd5 but does not have good piece coordination to disturb black’s king. The passed b-pawn(s) give some promise in the endgame too if white could last to the ending.

What do you suggest for white?
