Oops! That should be 32...d4!

After examining 32...Ra8, it doesn't look convincing to me.
Ruffian likes 32...e3 with a 1.64 score. I looked at it a little and appears to
be overwhelming fairly quickly. It looks like it might be the best move.
After 32...d4! you have to play through a lot of moves before Ruffian sees that
Black is winning. Here is a sample line: 32...d4 33.Qxe4 Ng3 34.Bxg3 hxg3 35.Qe1
Rc3 36.b6 Re3 37.Qc1 Bd5 38.Bb5 Rf2 39.Bc4 Bxc4 40.b7 Rb2 41.Qxc4+ Kh7 42.Qf1
Rxb7 winning.
This appears to be an interesting position for comps.
