I'll have to bump this because I have no clue what the triangle or the sideways D means?
Symbols used in chess analysis

The name indicates the player which pointed the variation/idea/comment. The triangle after a move "Indicates the future plan this move supports."
+/− indicates advatange, while +- indicates decisive advantage (both for white)
Finally, the sideways D before a move means "better was".

Friends,
I was looking at a game in Chessbase and found some cryptic symbols in it. Also, there were names tucked after some of these.
I am attaching the screenshot in which I highlighted what I didn't understand. Please help me.
