This element of uncertainty makes it hard to counter semi-bluffing poker players. Semi- bluffing players make huge bluffs chasing a strong hand.
Tight aggressive players find this strategy more profitable since their bets are rarely called by other players. Because, their table image has been cultivated in a way that other players think that they only play with strong hole cards.
