What you can do is find people who only play pot odds..... and then always bet 85% of the pot
In NL you have to 'tune into' people - you have to establish what their 'limits'
are - how much do they value TPTK? how do they react to a checkraise? if they check and you bet the pot - will they fold? Do they fear flushes? what does it take to get them to put down AA or KK, or TP on a weak flop.- loads of questions.
Stacks are very important in NL - implied odds can often be more important than pot odds. short stacks in ring behave very differently to full stacks..
The amount you bet also depends on your table image.You are far more likely to get an all-in call with AA if its only your second hand than you are if you've played 35 hands on a table and only seen the flop via the blinds.
Ppl constantly adjust their limits to you:If you got AA three times in a row and went all in each time - on the third you might well get ppl calling you with JT or 22. In the same way ppl will fold to a 0.3x pot bet on the river or call an all-in on the same flop and betting sequence.. depenedent on your and their performance over the last 20 or so hands.
Never slow play AA... you often hear this.. but actually you must mix your play up or else you become predictable. After a drought of hands its worth betting hard with AT suited in early just because you might take down the blinds there and then but also it tends to loosen the table to you.
As you say you need a bigger set of skills in NL... Generally in NL you are playing not only you current hole cards but also the last 20 you have played and those your opponents have played.
There's a bit more to NL.... but if I told you I'd have to kill you
Easy really.....
Tournaments you make a good point on. Generally if you get a good hand you simply push.. you often don't have the luxery of exploiting weaknesses in your opponents. Ring is very different.......
