Kitchen floor is 3/4 X 2-1/4 oak. Removed peninsula and as expected, no oak just subfloor. One end of the open area is a half circle. Fortunately, there are some short runs about every other board. I have watched Norm A. remove individual boards a number of times, but cannot remember how to handle the nailed side of the strip. Can someone give me a clue on out the get the nailed side out without damaging the ajacent piece?
