Bd2 is ok, but perhaps a bit passive. Your knight is defended by the b-pawn, so Bd3, Qc2, or even a3 are probably more active options.
good opening?

to ouachita. I am the white player. But okay for black, the last move wasn't to good.
The semi slav defense, is that better for white or black? and why?

Wow, i'm not so good in recognising all the openings yet. But you seem a very experienced player. So what opening is suitable for a strong defense than? I a familiar with this (attacking opening), but not so much with defensive openings.
What could you recommend me if I'd like to play a defensive game (or save draw as you call it.)?
hey,
I play this opening a lot in my matches. But my question to you is of this opening is a good one. I play it as white.. but is it a good postion for the rest of the game? if not, what could heve been better?
And: which will be the best next following moves?
