You can help yourself maintain a lead or get a lead by playing certain types of words. If you are trailing your opponent(s), your best bet is to play words that will open up the board and give you opportunities to make better plays. If you are in the lead, then you should play words that will keep the board closed off to your opponents and reduce their opportunities to make better plays. Advanced Scrabble players are always looking ahead to what their opponents might do. Get into the habit of considering what your opponent may do if you play a certain word and try to block any premium squares that your opponent may want to use during his or her turn. Keep in mind that blocking your opponent may not always be possible, but if you do it whenever possible, it may help you to hold onto your lead and win the game.
