A player skilled at very thin cut shots, and shots in which a ball must pass cleanly through a very narrow space (such as the cue ball between two of the opponent's object balls with barely enough room) to avoid a foul and/or to pocket a ball.

The heavy, finely milled rock (slate) that forms the bed of the table, beneath the cloth. Major slate suppliers for the billiards industry are Italy, Brazil and China. Some cheaper tables, and novelty tables designed for outdoor use, do not use genuine slate beds, but artificial materials such as Slatrol.
