Is this hand playable? Well, it can be playable if, for example, there are no bets to you.
Maybe sometimes its not very profitable because you can blow out all your opponent. But its better to get less profit than to lose.
By the way, I must warn you: its not very safe, but poker is like that.
Even experienced players lose their money just for... blinds. What is the best strategy for the Big Blind?
The river brings Qs. There is a possibility that he can win. You bet the same $6, he calls. Showdown What do you think he had? It will not be a surprise for you!
When it happens you should consider the particularities it creates.
In late position if someone raised you can call but again only once.
If the table is tight then its almost impossible to get a free card. Easier at the loose-aggressive table.
Because if therere three deuces on the board the probability that your adversary has the fourth is VERY small.
If youre too tight to play with the hands like that youll never win at the WSOP.
