lol, I just put it through houdini who says it's a toss-up between d5 and c5 on move 7. When are you going to get it? You do not know anything, about, chess, not except very some very basic stuff and not enough to make "analysis" for other people of.
If you play 7...d5
I can just simply play 8.Bd3 or 8.exd5 and return my bishop to d3. An my bishop on c4 as provoked a weakness.
I just loaded this position with an engine and it likes the idea of just taking exd5 than playing Bb3 instead of Bd3.
With the idea I said before of just targetting the d5 pawn. Probably even more precise that way. However, playing 8.exd5 than 9.Bd3 still keeps my bishop active while blacks bishop is terrible.
ok, this is getting disturbing.
