To build a strong pre-flop opening range, focus on position and hand strength. Open with a tighter range from early positions, emphasizing premium hands that can handle post-flop pressure. As you move to later positions, you can widen your range to include suited connectors, pocket pairs, and hands with potential for strong draws. Consider table dynamics, stack sizes, and opponents’ tendencies, adjusting your range if they are more passive or aggressive. A solid range balances value hands with speculative ones that can lead to strong post-flop plays, minimizing risk while maximizing opportunities for profit.
