What are some good defensive openings for white?

Opening theory doesn't make you better player.It's just hides your ignorance .Endgame and middlegame make you better player according to every serious writer , teacher or player.
It's easy to study openings and opening theory helps you feel better for yourself because you can play 15 moves Anand played but once the opening ends you are the same ignorant as you where.Nothing has changed.
You don't understand chess by studying openings.You understand chess by studying endgame and middlegame and for your level mainly endgame or you will end saying the hilarious:
"I know every line in Najdorf but I usually blunder in the middlegame or lose the endgame"
calm it Mickey G, put on your spec`s and read a bit I never at any point said to focus on the openings I said only to spend a little time so that you have a passing familarity with opening - gained not by reading books or trawling through databases but by experience of playing from a few common chess positions (italien game, spanish game, four knights, queens gambit ect) Learning these to maybe 5 move depth isnt much to ask and this will be reinforced by experience latter.
While you propose dogmaticly following somthing like the London system this wont help new players practice opening principles. Maybe a good idea if you want to focus on middlegame/endgame. Buy even then Id argue that middle games and endgame from different openings are very different - the player will have to come up with differnet plans for very differnet position and get more experience of diferent endgame positions.

Give it up windbag. Time for you to follow your own advice of "silence."
And spare us all your blowhard assertations that no one but you understands chess.
Get a life, numb-nuts. Blowing your horn in the forums won't give you one.

+1, Another perfectly reasonable opening system with the white pieces.

Indeed, and without the trolling and spamming behavior these threads would be as interesting as watching paint dry.
Johann Hellsten, Mastering Opening Theory (2012), is as good a books as any for building an opening repetoire.
But if you want to free up your study time, play a reversed opening from the white side, and hit the middlegame and endgame books, instead.
If you're under USCF 2000, that will make you a much stronger player.

You are absolutely right.Ending up discussing with a stupid like you certainly means I have a serious problem.Nuff said numb-nuts?lol.
Methinks the gentleman doth protest too strongly.
Try not to be so "upset" by what you read in these forums. Otherwise readers might believe that the criticism hit home.
On balance, the OP asked a perfectly reasonable question, but you were unwilling to offer anything constructive, and you got criticised along the way. Nuff said?
Have a Nice Day.
Stupidity never makes me upset , just surprises me.
As for the question the OP did , the most constructive is to realise that there can't be any constructive answer.In his level , offensive and defensive openings should be the last of his worries.
My comments were constructive but you are not intelligent enough to find them or appreciate them.Let me help you , check the first "page" of comments(If you still have difficulties maybe I will draw a picture for you).
The most funny is that people like you think that they can help others when they can't even help themselves.
If you really want to help ,don't help and they will all be grateful.Silence is the best you can offer.
