He didn't outplay me. I had 3-4 more planets then him. And a bigger fleet. 

When he attacked my side I murdered his fleet and he lost 3 capital ships. 

I could not go around because the other choke point that led to his HW was a pirate base. 

How do you kill his planet with freaking 8 repair platforms backing up his maxed out starbase covered by 40+ Flak frigates. He also had auxiliery government so I couldn't kill his planet that had maxed out emergency facilities anyway. This ****ed me off so much. 

After 4-5 times of my giant fleet trying to take the planet I rage quit and went to sleep (was 3am) 

Orgovs needed more then 30. Also to engage in a large battle like that you need to have power to endure an attrition war.  That means you need staying/tanking power, You will need 30-40 hoshikos and 20 cielos of your own. Kodiacks should be your front line cruiser, if you have Fleet supply extra some 30-40 additional LRMs is a good choose. 20 flaks and 20 corvettes to provide aerial covert for you fleet is needed, in addition I would also load half to all my carriers with fighter to shut down his fighter/bomber power. You'll need to be cap heavy for this, 1 Akkan to give your LRMs and Orgovs range to hit the starbase without receiving fire in return, A Marza with incendiary shells to negate the SBs passive regeneration, 2 dunovs to shield restore your caps and EMP blast to nuke the AM in his platforms as much as possible. If you can also manage to get a Sova with embargo on his production world that could tips the scales of battle in your favor by slowing down his production. Having your own Titan is a much needed plus. In addition to that you can try to culture bomb him, if you can rapalce his culture with your own you will be dealing a crippling blow to him by removing his AM regeneration and giving you your own. If he has a lot of SCs don't jump the Orgovs in until you have cutted his SC power down.

Hope this helps, these are all things you can do to try and dislodge him but it won't be easy. Unless you have a lvl6 Ragnarok your looking at a 20-30 minutes long battle that is gonna be one huge slug fest.

^ um...

This takes like insane amount of resources and seems unrealistic. It took me like 20 minutes to build my 50 bombers + kiodiaks Hoshikos etc...

There has to be an easier way! Come on. In original SINs 50-70 bombers was = gg. 

What is TAR? 

Do you have akan?

With target uplink and 20 ogrows set your fleet to hold position. Keep your support ships + combat ships with caps near ogrows then slowly inch in destroying one structure at the time. 

or

It seems you have upper hand but not quite enough to kick him out of his fortify position. You are playing game of attrition.

What I would do is plant sb on edge of gravity well where you can hold him away then move your ships into his core planets while he will be forced to move his fleet after you send in previously hiden 2nd fleet of ogrovs hoshis for structures and flak to counter his corvettes. What your sb will do is once he moves his fleet o folow he will be on equall footing with you - am reserves.

For some reason I thought you were TR...in which case you also don't have a ragnarov (ankylon instead, and you probably don't need to support it with much at pirate base if you pick furious defenses)....

If you have 4 more planets, you can build 2 more Novaliths than your opponent.  This will cripple your opponents economy.

Once his economy is crippled, you need to focus on the starbase(s) as they are the key component in the TEC defensive wall (Docking Booms replenishing his antimatter and Enforced Loyalty being the key abilities).  One thing I would try is a suicide fleet of around 50 Orgovs that target the starbase.  Plan on losing them, but make sure you have enough to kill the starbase.  With his economy crippled, he won't be able to replace it easily.  Novalith the planet and the militia bonuses are gone (as well as the ability to build frigates there).  Finally, rebuild your fleet and take the planet in a war of attrition.

Not an easy or quick solution, but it should be effective.

We really need some warning before your outbreaks of antics. I would have waited to bump stuff.

Hey, hijacking my posts doesn't give yours any more legitimacy. Though the ICO server clearly needs some therapy.

If your fleet was that much stronger than his that you instantly eliminated it whenever he touched your gravity well my guess is what went wrong on your offense is you didn't target the right stuff - for instance, your bombers hitting ships that were in range of repair pads rather than some that were not, getting torn apart by flak without dealing any real damage. Apart from the strike craft none of his defensive structures should be able to target you, letting you turn it into almost that same 'fleet vs fleet, not defenses' battle you were winning so easily in your own well. So, a matter of isolating his fleet, destroying it, before even moving into range of his turrets.

Are you aware that where in a destination gravity well your ships jump depends on where they exited their origin well from? Try moving very far away from the center of your own well before jumping. This puts your fleet at very long distance from the enemy planet when they arrive, possibly letting you achieve that 'fleet vs fleet' scenario again. If that still doesn't work it's super weapons, as was mentioned, which are precisely meant to be stalemate breakers.

*edit* read your post again - you targetted the repair pads. Should probably have left those alone and killed his fleet instead. Same deal with the Hoshikos, kill off some of the damage dealers instead (frail long range frigates being a prime example).
