Need help with Sharkfood Island

[ElPared]

The advice above is good: Scout, and protect your units. More than any other map, Sharkfood Island punishes you for losing units because the spawn is so far from a useful position that it takes at least a turn to get freshly spawned ones back into position.

It's for that reason that often the first person to attack loses on this map. This is because it's easier to take out several units on a counterattack than it is the do so on an attack. That's why I usually stockpile units and then try to provoke my opponent into attacking with a couple expendables, then try to take out 3+ units on the counteratack. Usually if you can do that and also put a runner on their spawn, forcing them to move a unit down to kill it, you can win.
