No. We win by an innings. For example if england get out for 200 then the score board will be
Pakistan win by an innings and 14 runs..
Its the most prestigious and dominant form of test win. You only bat once and your opposition despite batting twice isn't able to beat that score...
If we get them out under 214 then we won't bat again and the test will be our dominant victory of an innings.
What you are saying would happen if we would have batted first in innings one but here england batted first and we batted second and we won't have to bat again if England fail to beat the lead.
