I think these basics are very important
1) position is a key
- good positions means information for you, about other hands
2) watch how big stacks are (how many BBs you have)
- dont call / bluff if u are lower than 10 BBs
3) watch your opponent
- how he plays, if tight, or maniac, or ...
- how many are in game (if anyone fold,, etc..)
4) good hand
- dont play cards like 72o, find something with potential
- KQo (off suited) is not that much worse than KQs (suited) ->
-> dont play any 2 cards, just because they are suited
5) manage your bankroll
- so you dont loose everything
- 3-5% is good to play with
