In semi-bluffing, the goal is to bet or raise with a hand that isn't currently the best but has potential to improve. The strategy relies on creating two avenues to win—either forcing a fold with aggressive play or completing a strong hand if called. This approach is effective when you have drawing hands, like flush or straight draws, as it allows you to apply pressure while still holding outs. Timing is crucial; semi-bluffing works best when your bet size makes it difficult for opponents to call profitably. It's also more effective in position, where you can gauge your opponent’s reactions before committing further chips.
