if you have to choose, it's better if you have a good katu. because even if your opponent always bluffs, you can always keep up with your bets and bluff them with a good card. if you don't have a good card and we just bluff, then at the end of the game we will fold.
Bluffing requires a lot of gut. I mean, you will not be able to bluff your enemy if you are not really into that kind of strategy, you must really have a huge gut to do that since it is really hard to act while being nervous.
I did bluff my gambling opponents in an online game but that is different since it is online, they will never be able to see your poker face, the way you will be expressing yourself while doing that. Also, your opponents will not know whether you are bluffing or not the reason for me, having a great card and combining it with bluffing is a great weapon.
That is the thing, and I like the way you put it, which is the ability of your opponent to see your poker face. Even if you want to bluff you should know that you stand a greater chance of winning in most cases, than bluffing for no reason which could actually backfire if care is not taken, depending on how smart your opponent is.
The best thing is to have a pretty good hand and in that way you are only trying to use your other poker skills to drag your opponent into what you want them to think most of the time, but at least, you will not end up being screwed in a way when you have a good hand and sometimes we also have to realize that everyone is trying to act and play smart, so indeed, your own weapon can still end up being used against you, so you still need to be careful how you use it.
