Strange map, where are the agriculture/calender resources?
Techs and capital:
Start is fairly obvious we'll have to start with fishing to get our only resources improved. Building a worker first achieves nothing, So we'll start with a warrior to have at least some defence. It also contributes to happiness once we grow to size 5.
After 7 turns Fishing's in, i start on bronze working now, easily the best choice since there are only forests around. The warrior's ready so we start with a boat, at the moment the city grows to 2 i switch from 2 grassland tiles (2 Food, 1 Hammer) to 2 grassland forested hills (1 food 2 hammers). This stagnates city growth for the moment but getting the boat out asap and working an improved clam is much more important than working unimproved tiles now and growing a bit faster.
Once the first boat is out an interesting decision shows up:
I can build 2 other boats, second boat'll cost me 10 turns now, third boat some 7 turns since part of this boat'll be built at size 4. ~17 turns, total.
Also i can build a worker in 10 turns now and chop 2 boats subsequently this'll cost some 20 turns. This looks like it's a faster approach. since i now have a worker and 2 boats. However it costs us 2 forests and since the boats are coming later it'll cost commerce from the clam resources which'll be worked later.
Actually there's a third way which i choose, i build the second boat and start on the third, once the city reaches 4 i'll immediately switch to a worker with the intention of whipping it in such a manner that the overflow from the whip is enough to get the third boat finished.
Notice that it's very important that i whip now. the worker costs 60 hammers, i've invested 27 hammers atm. If i whip now 2 pop are needed to complete the worker (1 pop = 30 hammers on normal speed). This 2 pop whip will yield 60 hammers, 33 of these are used to complete the worker, the other 27'll go to the boat on the next turn which will subsequently be finished. If i'd waited one more turn i'd have invested 36 hammers in the boat. I could then only whip one pop of which 24 hammers would go to finish the worker, only 6 would go to the boat, 1 pop whips should generally be avoided unless your city is at size 2 and you need a monuent or workboat.
Exploring:
I find out quickly that i'm on a sort of snaky continents map, i meet Mansa
Not obvious from the map atm but he must be able to reach me by land since i don't think he can have built a galley yet. I'm not afraid he'll attack me but it's important that i settle my first cities towards him (Blocking). I find out he can reach me via a choke point, it's very important to get here first, i'll seal of a lot of land for myself this way.Note the annoying peak just at the point where i'd want to settle.
In general and especially on this map (there's a lot to explore) it's important to keep your scouting units alive. Once i see the first animals appear i'll try to end each turn in a forest even if i can move only one tile instead of two .Sometimes this can't be done, at least try to choose a hill in this case for some protection. Once warriors appear scouts'll die anyway so i don't care that much after this happens.
BW reveals copper in my BFC (abbreviation for tiles that the city can work). I next go for the wheel to get copper connected, all the other techs are useless to me atm. I can't remember playing a game where the order of research was as easy as here.
Plan:
Connect copper asap
Then as i see it i can basically choose from 2 plans
1.after first worker grow back to 4, build/chop a settler and an axe and settle the choke point.
2.research masonry and sailing chop/whip 2-3 workers and chop the Great lighthouse (GLH) subsequently. I probably don't have time to settle the choke first and then chop GLH on immortal.
This map screams Great lighthouse, having two extra foreign trade routes in each coastal city you settle is huge on a coastal map. I'm not sure if i can reach more civs apart from Mansa since i don't know this type of map very well, it seems likely however.The map also doesn't seem too crowded so i'd probably have room to expand after chopping GLH.
There are 3 reasons why i might not do it:
1. Further scouting has to reveal how close Mansa is in other words how
much time i have to settle the choke.
2. Even if i start beelining for GLH an AI might beat me to it, this chance is not that big but it'd be bad if that happened.
3. In the Ghengis immortal student game i chopped GLH and aborted the game 1260 AD since i was totally winning without having to do much more than just plunk down cities that payed for themselves immediately with the trade routes they received, i and some others agreed that GLH is just an overpowered wonder if the circumstances are right taking out all challenge.
.
(I swear I didn't remember where they all were... honest) 
to him 
I'll have to re-think that. I should probably be more aggressive with my settling and settle closer to monty to grab as many of those happy resources as I can as I can.
