Playing against the Queen's Indian as White

Don't think @Optimissed is very well.

Is he ever?

I apologize for the racism against you on his part.

Well, it's the least we can do.

Now can we please get back to the chess?

It's  a figure of speech

back to this please?

Well... that's another way to interpret it...

So let's get this straight? Mr @Optimissed, aka the great logictor has put forth that... the a3 Petrosian variation of QueensIndian defence is a certain draw, a Certain draw, unless the players happen to have an elo rating of 2311 or higher. At which point there is the possibility, the slim possibility, that one of the players might play for a win?! But Mr Optimissed has declared this opening to be quote, rubbish, anyway, and that only somewhat stupid pushovers would dare play such a rubbish opening. When given a fine example of a game between two world champion players, Mr Optimissed reacted like a feral dog, hurling insult and abuse, and declared that game did not count, because he knew better than at least 3 world champions that the opening was rubbish. Mr Optimissed did, grudgingly, admit that Mr Kasparov was probably a better player, but that he, Mr Optimissed, was a superior logicator... As for how he came up with 2311 rating is somewhat unclear? Mr Optimissed would appear to have taken 62. something percent of something and divided this by something else. Or something. And then declared most anybody else as too dumb to follow his superior thinking. Unfortunately Mr Optimissed appears to be unavailable for comment, as he has either been muted or taken a huff puff. Mr Optimissed has declared Mr Lion an idiot, amongst other things, and vowed never to talk to Mr Lion again. Ever. When asked for comment, Mr Lion declared he was both grateful and relieved. And hopes that Mr Optimissed will get appropriate medical treatment. 

I would like to communicate my most heartfelt approval and elation at your wonderful response to Mr. Optimissed.

Would you be willing to explain your "superior thinking" to us lesser mortals, Mr. Optimmised?

its too complicated for people like us to understand

Yes, after all, we're mere mortals, aren't we?

Hey @Optimissed? Please could you explain the 2311 thing to us lesser people...

But what about the 62. something percent thing? Kasparov is great player, but as a Logicator he must bow to @Optimissed...

What do you think of this variation?

Isn't it

4... Ba6 (objectively the best)

4... Bb7

4... c5

In my opinion, 4... Ba6 is better, but I think 4... d5 is acceptable if you play either ...Ba6 instead of ...Bb7 or after cxd5 play Nxd5! instead of exd5

Well what are your views

Yes, I've never liked a combination of ...d5 and ...Bb7

I feel like this line is okay for black though:
