In order to ensure a good experience on your first LL games, play the way you usually play, with the following differences:

First 3-4 games

1) Give good clues ASAP.

2) First rule is valid even if leftmost isn’t playable.

3) Therefore assume any clue not given ASAP is not a play clue.

4) Suppose every clue hitting chop is a save clue.

5) No finesses.

6) Never "play left" among several newly clued cards.

The last rule may sound scary, but it’ll help you notice those situations where it’s indefensible to not play left – those situations where there’s no way leftmost isn’t playable because it’s too obvious, i.e. where it’s logical to play left. And it’s just for your first few games.
