depends on your position on the table, your table image and the image of your opponents.
so not easy to say.
- some people flatcall or check in this situation, i dont like that AT ALL. too many bad hands come along and make chance to win.
- potbet, makes the playingfield smaller most of the times in serious games, and gives you a lot of info about their hand. downside is that after a few times, people will notice it and play around it.
- 5 or 6 times big blind, also makes playingfield a lot smaller most of the times, even A9 A10 might fold when you do this.. so this bet depends on your kind of hand. if you have AA, you want others in with A9...
each player prefers a different style, so ive them all a try and find out what works best for you
