| I show bluffs a lot since I want action.
The best time imo, is at the end of a session vs a reg you will be playing with again. If you do it at the start of a session there is the whole "hes not going to bluff me again" thing on there side. Not so bad if you have the balls to keep bluffing them. I like to leave them with a bluff, and get the action next time. |
