Well, ive been playing poker for about 4 years now, but online only for about 4-5 months. at xxxx. In both follow up betting is a key element of any hand.i find myself in more of a dilema in this issue in online poker.suppose im to get AJ pre-flop and i raise a few times the big blinds (doesnt really matter how much), and then i miss the flop....in real poker i find myself able to see other people and have an easier time determining wether or not they hit something. in onlione poker, if im first to talk, its pretty much a gamble, isnt itso i guess im just looking for some good advice form some experienced players. i feel that this is probably the weakest aspect of my game.i will sometimes get re-raised or sometimes i dont even make the follow up and then wish a did and i just get rather confused about the whole thing.is there any specific time in which a follow up is more likely to work than at other times?hope to get some good tips,thx in advancep.s what are the tags for?
