Many years ago, I put down T&G floorboards in the bedroom. I've ripped up the carpet in the landing to continue T&G into the landing.

The problem is that, when I did the bedroom, I used a 190mm, plain board to avoid a joint over the pipes. It seemed a good idea at the time but, over time, traffic has created a crack in stages, length-wise along the 190mm board.

Any suggestions as to how I can fix this, firstly in the bedroom and then before I attempt the landing?
