how to read analysis ?


All you should be using an engine for is to check for blunders and missed tactics.
All that + and - crap will do you no good right now.
But to give you a quick answer:
+ means advantage white.
- means advantage black.
+.33 means white is better by 1/3 of a pawn.
-.5 means black is better by 1/2 a pawn.
