It seems to me this is a very difficult situation.

You have a very talented horse that does not
appear to be rateable. I definitely think the horse
was hurt by being restrained in this particular race.
I think the horse wasted a lot of energy fighting
and then running inefficiently. She may have lost
anyway, but she was definitely not going to win
with that kind of chokehold early with the two horse
pressing. I would have been inclined to loosen up
earlier than Gomez did if she fought that hard.
Seems like that should have been discussed.

I thought that a trainer is supposed to take care of
this during training. Did they train her in company and
she was responding well to being held back but just
got excited in the race and took off?

Its a tough way to experiment... during a stakes race.
And with the length of that stretch run... Indian Blessing
was not having any fun.
