I've been watching some poker tournaments with Antonius, Negreanu and Cates lately. Most of the time the person with better combination actually wins, but there occur some great bluffs from time to time as well. Do you think it is better to fold if you don't have at least one high card in a pair or two cards of the same suit? Is it worth to try out overbetting tricks when you really have shitty cards? When I tried playing poker, overbetting usually made me fold, because it is a hard psychological attack for me and I am not the kind of a person that is willing to risk a lot. But I am bad at poker. What is your opinion on this matter?
Bluff doesn't necessarily need to be an overbet. It may be 30-40% of the pot when you are trying to make some some part of his range to fold for example 2nd, 3rd pair and you have air. And when you get called by Top Pair and better you shouldn't think, bluff doesn't work because you haven't targeted to fold that good hands on the first place.
Overbets are usually used when you have air(bluff) or nuts(the best hand possible) - it should be done with certain frequencies though - you can't 100% overbet when you have bluff, or only overbet when you have strong hand, because players will figure you out fast.
