I know calling a raise in limit with ATo is like hanging your junk in a meatgrinder.

But I watched Sauce do it in one of his videos.... The part I forgot was that he was pretty sure he was going to end up HU, while I clicked call before that part occured to me.

Is this a spot where I could raise to attempt to isolate?

All of the players are really tight passive at the table.
