The generally accepted practice is to run two longitudinal cuts along the boards. One about a 1/2 inch or so from the groove edge, and another about 1/4 inch from the tongue edge. This can be done with a Skil saw or preferably a FEIN supercut or multi-master. This can also been done with a router and proper set up jig. Any competent installer can do it this way or with a method of their own devising. Then a long diagonal cut is made bisecting the centre part of the board, and using a hammer and chisel, the pieces are easily removed. There is a little more to it than that, but the key is to isolate the board and remove the cut pieces. The new board is then cut to length, cutting the tongue end off and the bottom of the groove along the length and the groove end of the board. Fastening the board in place can be done in a variety of ways, but care must be taken to NOT face nail the board in place. My own method is to use a urethane glue which will do the permanent holding, and supplimented with a few spots of hot glue for immediate bonding while the urethane glue sets up. Make sense? If not, I will try to explain in greater detail.
