Even if you get out showing aggressive intent, it is alright.
I'm not sure why Kohli's definition of intent is being so criticized. He's right, you can't keep just blocking all day and look to spend 30-40 overs at the crease not doing anything cause there will eventually be a ball that gets you out in these conditions, unless you're Rahul Dravid who can do that and just wears bowlers out mentally, only he can do that. You need to look to put pressure back on the bowlers and you need a bit of luck in the process as well.
