The probability of being dealt any two suited Hold'em cards is a who ing 23.5% , and each player is
When most players think of suited cards, small and middle suited co ector hands like 8s,9s often come to mind first. It is totally correct that being suited adds a lot of positive expectation to a hand like 8,9 but more so in un-raised pots with many players rather than short-handed. These type of hands are meant to make straights and flushes which are usually needed at the end of any loose multi-way action, and being suited gives you an extra way to win.
Aside from co ectors, many players find it wise to use a general suited guideline when holding big hands when facing raises from players ahead of them. An example of this is a player holding Ad,Jd when in late position and facing a raise from early position. Many will choose to call or re-raise with this hand, but would fold if their two cards were not suited (i.e. Ac,Js). Hands dealt in the blinds are also often played with the same strategy; for example players will call a raise in the blinds with a hand like Ah,6h while folding with a similar As,6c.
While it's true that junk hands like 9s,3s, can occasionally hit a flush and win a pot, it's far more likely that it will be to ed away on the flop, or trap the player for even more bets in a weak draw or with a small pair. Worse yet, the player will make their flush only to lose a ton of chi to another o onent with a bigger flush. Although you may witne others at your table limping in with anything and everything suited, trash hands like these should routinely be to es away in most circumstances.
