Nutty

A client of mine has a nasty stain about 20 inches in diameter that encompasses about 10 widths of hardwood floor. Anywho, I have done an internet search for this topic and have become familiar with it. However, does anyone have any advice as to what ehy have experienced?
I understand that the bottom of the groove will need to be removed so that the piece is able to fit the tongue. Here's the big Q......When gluing say the final piece in, is it best to glue it right to the subfloor...or should I just glue the "groove"? I am worried about expansion/contraction and eventual floor buckling if I glue right to the subfloor. Should I be concerned? I was going to use liquid nails as the glue. I am going to try and NOT face nail. Is this a good idea as well?
Thanks in advance.

I glue to the groove and tounge, and to the subfloor. Have not had any major problems doing it this way. Also, I have found 5 min epoxy works best, that way I can sand the day I make the repair.

make sure the sub floor is dry, I put felt back in place and glue the t& g and face nail minimal.

I have a major groan from a gluing to the floor. Just do the tongue and groove, and let it move. I won't go anywhere big, and if it has to move it is not fighting the sub.

What wood is it?

thickness?

I've use epoxy and Tightbond II Carpenters glue. I use the carpenter's glue for prefinished flooring and actually like it over epoxy. Longer cure time but more user friendly cause it's water clean-up.
