played a little this morning - lost TvT when i could have won :|  - my marines/marauders got separated from my tanks (tanks couldn't get past my bunkers, woops)  otherwise i would have had that game EASILY.
		
		
	 
Ahhh, I hate it when I forget to lower my depots and let my tanks out!  I've started to learn when moving a tank to make sure he can get outta my base!
	
		
	
	
		
		
			Thanks guys, I'll try the immortal/colossus combo and get some void rays.  Gahhh, its so annoying, he just farms and farms and farms and turtles.
On another point, is Terran superior to Protoss late game? Cause it seems that Protoss is focused around mobility (with the warp thingies) and with deception/tactics (with the sentries) whereas Terran has so many strong machines.
		
		
	 
I LOVE it when somebody turtles, they are a piece of cake to deal with.  First and formost, you want to make it so that they cannot LEAVE their base.  Control their exit points, don't allow them to even get to their first expansion.  Sometimes it is too easy for them to defend the expansion with the base, but do NOT let them out any further.
Second EXPAND yourself.  If somebody is turtling in with towers and tanks, it leaves you the ENTIRE remaining part of the map.  Keep at least 3 bases running and harvesting, preferably on the rich veins(Yellow crystals).  And PLEASE build enough gateways/stargates to USE those resources as fast as they come in.
Next, you need to build units that will be able to attack towers while staying outside of range.  Generally as protoss this means void rays and carriers.  A turtle is generally very immobile.  Use this to your advantage by harassing his ass.  Because he is turtleing, and you have more expansions than him, you can afford to lose more units too!   The worst thing that happens is that you cannot break his turtle and you have to wait for him to run out of resources.  Time is a turtle's enemy!
To effectively attack a turtle, remember that a lot of his defenses are towers, and as such cannot move.  You can usually flank his defenses.  Or at the very least only have to deal with a small portion of them at a time.  As YOU get to pick when to attack, do NOT fight on his terms.  Pick places he is weak.  Use decoy attacks.  Hit and run.
