Admiral's Advice: Defeating a Single Opponent
small/medium map with medium asteroid groupings, 1vs1: Fighters, particularly bombers, are a must in the early game. Whoever manages the early game well will win. Go from fighters to frigates and the game should be over before anyone has destroyers.
small/medium map with large asteroid groupings, 1vs1: This is a bit of a longer game, because you can't easily hit a resource operation early on. Build corvettes in case your opponent tries fighters. You don't need a second resourcing operation until after your first pop-cap upgrade, so building corvettes is an effective way to limit any early game conflict. Don't ever build fighters, because you simply can't take on the mothership that early. Go from corvettes to destroyers, and mix in some platforms. Don't build as many platforms as you would in a longer game, though, because mobility becomes more important on smaller maps (its true, even if it sounds counter-intuitive). This game should end with destroyers.
Large map with medium asteroid groupings, 1vs1: Corvettes are an absolute must in this game. You have no choice but to expand to a second resource operation in the early game, but the map is too large for a bomber assault on your opponent. By the time they would arrive at your opponent's resource operation, any reasonable opponent would already have defenses in place. Use your corvettes to guard your second resourcing operation until you can position platforms there. Use platforms alone to guard your mothership. No one can succeed in the early game on such a map, so optimizing research and build capacity is essential. Get a decent fleet of destroyers and then a lot of battlecruisers. This game is moderately defensive. Use whatever offensive strategy seems useful at the time to defeat your opponent. Resource operations are vulnerable in the late game, so building a late game fast strike force of bombers can be very effective, and they double as anti-subsystem ships.
Large map with large asteroid groupings, 1vs1: This is the ultimate defensive game (in 1vs1). The first resourcing operation you have can last you for a while, but all you want to build is platforms in the beginning. Move them to the next place you want to resource from once you start building resourcers to harvest there, and make sure you always have the necessary forces to defend every place you hold. Hyperspace inhibitors are very important, and you should position your ships with inhibitors in a manner that prevents the enemy from getting anywhere near your mothership. Large fleet conflicts are bound to happen, so make sure you have your big ships as upgraded as possible. Finally, make sure you can destroy subsystems. Battlecruisers are helpless without them, and destroying your opponent's mothership ion cannon will often give you the win. Turn your mothership into a mobile weapons platform, and use it as an offensive weapon. Just stay away from your opponent's mothership with your own until their cannon is destroyed.
