My question for the forum is, what are the low end of the hand ranges you'd expect a fairly tight, solid regular to push with in this spot against another player with a similar style? For example: (55, ATs, KQs)

Also, getting about 1.9 to 1, what hand ranges would you be willing to call with as the original raiser, based on the hypothetical range you've given your opponent?

I'll add my thoughts later if this thread goes anywhere.
