In heads-up matches, the strategy generally shifts to a more aggressive approach due to the increased frequency of marginal hands. In Texas Hold'em, you'll widen your hand range, playing more hands from both positions and relying on positional advantage to pressure opponents. For Omaha, caution remains crucial, focusing on drawing potential while still playing a broader range than in a full table. In Seven-Card Stud, observing exposed cards is even more critical, with aggression targeting when you perceive an advantage. In Razz, you’ll often push low hands harder, exploiting your opponent’s weaknesses. The emphasis in all variants is on reading your opponent, adjusting quickly to their tendencies, and controlling the pace of the game.
