Usually I like to buy into the 1/2NL games with 150. Say I lose some hands and get down to around 100 it really limits what you can do.
Calling raises with 78s is stupid or trying to set mine when someone makes a big preflop raise is also stupid.
Then spots where bluffing usually works (like when middle card pairs or you're drawing to str8 and flush card comes) people say fuk it he only has 100 left i'm going all in.
Then they can just blow you off draws because they can never get hurt that bad if you have monster.
I always seem to play better when I have a lot of chips because players just can't push you around if they are also deep. Take for example last night have Ad3d and flop comes QdJd9s I lead out and bet this flop into a big field. Then 8d come on turn I bet again two guys call. River is blank and I make a huge bet and one guy calls while other guys says he has top two and knows it's no good. If I would have only had 100 left the toptwo guy could have just blown me off my hand. Since I had a lot of chips and he was deep he had proceed more carefully.
