I wasn't really worried about him holding a 7, more like he was raising and betting as if for value. Very likely he held a weaker Q.

I have found that I very often get pushed off a hand if I value bet 1/2 pot. Turning that up to 2/3 changes things for the better. I am still adjusting to this limit and that seems to be an adjustment I need to make for this limit.
thanks for your comments.
