I don't see a reason to move the settler. More food would be great of course but there's no visible reason to expect it in any particular direction. I plan to start by moving the worker W just in case that reveals something of interest. I expect it won't and I'll then settle at the start position.
The following thoughts are based on the assumption that the two hidden tiles NE,NE and SW,SW of the start don't have anything special. If they do things might change.
It is a low food start. Maximizing early growth seems a priority. One part of that is to produce a settler as soon as possible - the town the settler builds adds another source of food. There are two ways to further boost food: 1) Build a granary so quickly that it doesn't delay the first settler by much. 2) Find a food bonus tile and settle it quickly.
With extreme measures (mine, mine, chop, without pausing for any roads) I think that a granary can be built with only a two turn delay in the first settler. But this extreme approach has some costs. Research is slower because roads aren't built. Extra worker turns are required later to come back and road. Worst of all no warriors get out exploring. And that means it won't be possible to pick a great location for the first settler. So although it could be a strong opening this approach is very much a gamble.
A slower approach to reduce the compromises (e.g. build roads along the way and start with a warrior) also reduces the benefit of producing a granary vs. starting with a settler.
A settler first approach seems safer. And it is good if there's a food bonus nearby for the settler to claim.
I think this looks like a good opening sequence: Worker W, mine, road, NE, road, mine. Build warrior, curragh, warrior, settler. That sequence should finish exactly when growing to size 3. There's just one production overrun when building the second warrior. Note that the two warriors and curragh can be built in any order and the sequence still finishes at the same date. I like warrior first to get a quick look at some of the immediate surroundings.
I plan to use that sequence but it is subject to change depending on what the exploring units find. There's jungle to the north. I'll send the first warrior west at least two steps. Then probably north and then west. Curragh north. Second warrior south. I want the two warriors to explore the nearby terrain for a food bonus before the settler is produced.
I'm unsure about the curragh in Predator class. The Predator attack strength 2 barbarians sound wicked. I expect it will be important for Predators to attack barbarians instead of defending against them. Curraghs, with no defensive terrain available and no healing in the field will be especially vulnerable. Early curraghs may not be a good idea for Predators. OTOH, the "atypical" map may need them.
I plan to initially research Writing at maximum. It isn't clear how soon I'll be wanting Pottery so I'll start by heading for the Republic slingshot.
