In the thrilling game of poker, deciding which hands to play pre-flop can be crucial. It's said that on average, only around 18-20% of hands are playable pre-flop. This percentage, however, can vary greatly depending on the player's style and strategy. Some players may choose to play more conservatively and only play the top 10% of hands, whereas more aggressive players might venture into the 30% range. Ultimately, it's a strategic decision that can greatly impact the outcome of your game.
