德州扑克悬牌之前(PRE-FLOP)如何下注，取决于你拿到的两张起手牌(也称窝牌STARTING
HAND OR HOLE CARDS)的强弱。如果将起手牌的强弱用数字来衡量，最弱的牌值为0，最强的牌值为40，那么德州扑克所有起手牌的强弱值可用下图清楚的表示出来。
总体来讲，只有那些深绿色，蓝色及紫色的起手牌才值得你去玩，其它牌都应弃掉，除非情况特殊，比如说你是大盲注而又无人加注。如果你处于后面的位置，10点的起手牌你就可以跟注，但如果你处于前面的位置，则需要19点以上的起手牌才可以跟注。
也有人根据牌的强弱，将德州扑克起手牌分成8组，每一组牌代表一个强弱级别，处于同一级别的起手牌可以采取同样的下注方式。
