Heads Up Talk

[New Guy]

So as you know I've been playing alot of hu sng's and been doing really well. But every now and then I run into someone that I just feel is better than me and they out play me.So heres my question,(I'm not even sure there is an answer) What makes a sng player better than a good player? Is it they are willing to bluff more?, bet better,disguise(sp?) better, or alittle of both.Im know its a combination of all of them but i'm just looking for some thought as I want to get alot better and never feel outplayed.!! Thanks in advance.

On a side note, what are the pro's and con's as far as a hu sng and a hu cash game? Thanks.
