Guarding against f5.

"It's not easy for Black to reach a blockade against the rooks." - Krush

With the queenside liquidated winning chances go out the window. Now Vallejo wants to play for a win, although the weak squares around his king make this problematic.

The bishop is pinned against b8.

[ 34...f5 Black might be able to hang on to the bishop, but he can't win with such an open king. 35.Rb1 Kh7 ]

Now it's a dead draw. [ >=36...Qc1+ Black could have played for a few time trouble tricks without much risk to himself. 37.Qf1 ( 37.Kf2 Nf6 ) 37...Qd2 ]
