Steve, I think the rounded bottom of those strips indicate the top was sanded too deep. This happens a lot. The ols 3/8ths floors were good for one sanding. Do it 2wice and the nails would show.

Jly, if you are removing cabinets this job just got easy. Chip some tile, set your saw depth and cut the sucker down the middle. Leave the diagonal sheathing. Greg was right about that and I think Jeff meant more or less the same. I have cut to the joists before though. I just ran a saw around the perimeter which leaves 1.5 ".
