i heard about HUD But i would like to learn what i should consider when i
reconize player..
An HUD is an excellent tool and in some ways you are putting yourself at a disadvantage by not using one because so many other people do. You can get free trials for Pokertracker 3 or Holdem manager 2....so might be worth considering giving it a go.
i really like that you said certain aspects of their play such as preflop
limping, min-betting/min-3betting, making weird sized bets.
could you explan littlebit more about these?
limping -- Limping preflop is bad and bad players normally limp. Play tight starting hands and raise them preflop. If, for example, the blinds and limper fold you just made an extra BB. If blinds fold and limper calls they will often make a worse hand than you (worse kicker for example) and you can value bet them over 3 streets. Because limpers are (normally) bad players they often overvalue hands like one pair with poor kicker.
min betting/min 3-betting -- again indicates a bad player. I see min-betting quite a lot at 2NL and I swear they are just betting because they don't know what else to do half the time! Or sometimes it means they have a weak made hand. In both of these situations it is quite easy to make them fold by making a decent raise whether you have something or not. Basically if you are going to bet you should bet properly, in general at least half the pot. Players who don't do this are usually weak.
making weird sized bets -- sometimes their bet size doesn't really make sense with what has happened previously in the hand. There are different types of weird bet....
Betting too small: if they put in a decent sized flop bet and you called with a draw for example, and then their bets start getting smaller on the turn and river it often means they don't have much and are scared of putting more money in, so you can raise it up and see what happens.
Betting too big: if they haven't shown much aggression in the hand and then they suddenly bet big it can be a sign they are
bluffing you. I have caught people bluffing before because their bet size was unusually large. At the same time you need to be careful with this one and it is dangerous to assume villain is bluffing.
There are loads of other things you can look out for like 3betting too much, c-betting too much, being too passive etc. You can keep some track of this stuff without but having an HUD makes it soooooo much easier!
