Pre-turn - Assess the situation and find a target, the oil near Copenhagen. The spot is surrounded by at least 2 culture cities, Oslo and Calcutta, that has to be removed.
I remember the speculation of Greece oil, but the island city doesn't even have a harbor, so that won't be possible.
Move all bombers from the northern part of our peninsula to the allocated spot near Indian borders. Bomb Oslo down from 15 to 7 pop. Shuffle some workers around doing meaningless tasks.
Remove radar-tower near Oslo with bombers from the navy and continue whacking Oslo with bombers from the mountain-spot. Bomb Oslo down to pop 9 and almost kill our army against a 2hp flak. Kill the remaining 1hp infantries with sipahis and raze the city.
1505AD - The immense Indian airforce (2 bombers) hits nothing.
Next target Calcutta is showered with bombs.
Continue with Copenhagen to diminish their cultural borders after razing the city.
Move in 3 sipahis to raze Calcutta next turn.
Use bombers to destroy some roads and hurt some units in Bombay.
1510AD - Destroy Calcutta, but the borders doesn't shrink?
Ah well, on to Jaipur then. And Stockholm.
1515AD - Destroy Jaipur and we have oil. Change builds to tanks.
We have to wait to mobilize when United Nations is built in 6 turns.
Destroy Stockholm.
Use the rest of the bombardment to cut roads.
Irrigate a couple of tiles in cities to add pop and still have the "magic" shields of 50 and 100.
Someone ordered a tank-army? Disband sipahi-army in Iznik.
Try to trade something, not a chance. India won't give up Rocketry, so I steal it from them.
We have aluminium near Edrine if we ever need it.
1520AD - Bomb Karachi down to 1 pop, move 4 tanks to the area. The last tank find an Indian infantry guarding Bindasara, a leader! Bomb the inf and kill the leader.
I can only reach the city in 2 turns, so I continue bombing roads to leave just a path. I intend to grab the gems by Delhi when the time comes.
1525AD - Not much
1530AD - Karachi is razed, moving on to Delhi. Capture a russian settler.
1535AD - Delhi is gone and we have a road towards Babylon borders. Unfortunately there are over 30 Bab-units blocking the way to create another airfield.
1540AD - Built an airfield on a mountain next to Babylon borders and move bombers there.
1545AD - We build UN. Time to be sneaky.
I sell Fission to Babs for Amphibious Warfare and all their 1166g. Try an immediate steal and we are at war.

Peace with India for 308g so their units attack the right color.
Capture a Babylonian worker on gem mountain and build a colony right away. Lower luxtax to zero and all is good.
Use artilleries on stacks of red units and bombers on everything else in sight.
Kill 25 units.
Destroy Punjab.
1550AD - Raze Lahore. Kill another 25 or so units.
Our military: 40 infantry, 22 tanks, 1 tank army, 6 sipahis, 48 bombers and 49 arties.
Babylon: 128 infantry, 2 tanks, 3 TOW, 11 arties, a bomber and a few fighters.
