Well done Dobie,
Yes well for sure there's a different mind set to the 3 variations (Limit, Pot and No Limit)
But the basic principles are the same, in that during the early stages you need to play tight and 'position' is even more vital, in that it's the low card on the first round of betting card 3, (1st up card) that opens the betting and not the first player on the left of the dealer as in Omaha and Holdem ..
Also the key is, watching the game and the cards as they are dealt, remembering the numbers and suits of pass cards from players who have left the hand as the 'streets' are dealt 4th, 5th and 6th street ..
All this helps to asses what your opponent could have or not, and also what possibles and percentages of what your own river card has ..
That is to say, making sure your not drawing dead , or to a hand that can't win ..
Good luck mate and enjoy the game
