I think Jastrow's idea was not to move the worker NW but instead to move him SW+W to the banana tile so that he could quickly hop on a forest and chop it. Please correct me if I'm wrong...
Perhaps he meant something else. Moving the Worker SW G + W western G Banana actually requires 1 additional turn relative to moving the Worker NW G + SW G For to start Chopping a Forest, and would require the same number of turns to get to other Forests in the west.
The only other Forest that we'd be closer to would be the GH For, but I'm not particularly keen to Chopping it first. Having that 2-Hammer square helped when we wanted a bonus Hammer for building a Settler by working a G For + a GH For square. Given that we could have the G Pig square, this approach may not matter, but it seems like it would be a stronger play to Chop a GFor (compared to Chopping a GH For square), since we won't really have time to Chop and Mine a GH For in the short term.
Okay, I can give up on the idea of parking the Archer on the G Pig square. However, in order to get a City with Seafood + the Pig, we'd be settling on Turn 3, with us pretty much committing to moving down the peninsula with a Settler on Turn 1.
In addition, I dispute the claim that we could accidentally mess up a Seafood Resource by settling either NE + E of the G Pig or 1NE of the G Pig, since the screenshot appears to show a square of land SE + SE of the G Pig that could still be settled for any hidden Seafood.
If we honestly believe that a Pig + Coastal Fish location will exist down there, such that we'd want a Pig + Moai location down there, why not just settle on the G Banana and build a reasonably-fast Settler for that southern peninsula area?
At some point soon, we're going to have to commit to sending the Settler in a particular direction, be it toward the G Pig or be it toward the north-west where the Scout is located. I've seen nothing compelling revealed by the Scout yet... and no sign of Hills are on the horizon, either, which we would have been able to see since there aren't Forests blocking our view.
What would then make us want to move the Archer 1SE to the GHFor next? Only a Seafood Resource appearing 3S of the western G Banana, in my opinion. If the Settler moved 1W Grassland Banana + 1SW Grassland (1SE of the western Lake), we would reveal that square. Then, you wouldn't need to worry about missing a Seafood Resource in our capital, although we could get it later anyway, as I said above, with another City, even if there was a Seafood Resource there. Of course, if another Crab Resource appeared 3S of the western G Banana and you still did not think that settling 1SW of the western G Banana (1SE of the western Lake) would make for a good capital, then I'd say that we shouldn't even bother to reveal that square now.
Moving the Archer 1NW GFor does give us slightly more info than moving him 1W GFor, but only if we don't plan to move the Scout W + SW.
Also, the Scout could be just as easily used to prevent Jungle growth on the G Pig if the reason for not wanting to park the Archer there was so that we could get to work on Worker-stealing.
What would we have to reveal to the north with the Worker or to the north-west with the Scout to justify not settling by the G Pig with our capital? There's a Lake, a G Banana, and a GH square to the north and literally just Grassland Forests to the north-west so far.
If we really are okay with committing one Worker action to exploring, why not send the Worker 1NW Grassland + 1NE GH? It would take us just as long to get to the G Pig square as 1NW Grassland + 1NW GFor with the Worker. We'd reveal more squares by going NW + NE and the square that we wouldn't reveal compared to going NW + NW is a G For, so its chances of containing a Resource are relatively small.
I'm still fine with moving the Worker 1NW Grassland and reuploading a paused saved game. When I get some time later this evening, I'll try and use fog-recreating to see if I can discover anything more about our starting area.
