Battlefield stories: Cannon rush, and how I was owned

Beside theoretical knowledge I am collecting through tutorials, my replays, and video commentaries of our great casters, practice is something that I do bad. I am writing this after loosing three in a row as Terran. I also win one. And this is time when I need to stop pushing my luck and think of some things. Early rush is bad thing, punishment not to be prepared from the beginning. When you see your five workers parked on the mineral line the game begins. You shold be at the right speed from first click. I guess there are a few details that always spoil my build...

Showcase

I was (don't laugh!) cannon rushed. It is so thin line between being and not being cannon rushed. I did 4 major mistakes (reffering to what I said in my article). If I do right at least one it would be extended game and he would be stopped, and probably loose.

First - I didn't prepare well.

I didn't pay attention that Steppes of War is map that is absolutely made for such rush. Base field is huge and you don't cover your sight everywhere in the early game. I did know that fact, and I should pay extra attention to this fact.

Second, I was not concentrated

After first supply on my entry I started barracks, moving around a bit, handling SCVs etc. Then I assigned worker on barracks to build second supply and finish the choke. I did this using "shift" queueing so it starts right when baracks get done. After that I leave him do his work and go deal with rafinnery. Actually my mind was set up as "choke done" when in fact the final supply doesn't choke until it is started. And that was the moment when little guy sneaked in. I am talking about few seconds. I spotted the cannon after my factory was done but that was already too late. Having two marines was not enough. I was targeting a probe but cannon saved it. He keep planting cannons closer and closer. It looks desperately lost game.

Third, panic!

I know that I should not panic, but I failed. I was doing so noobish actions that I would better delete this replay. Sending marines raly point to attack cost me four of them for nothing. Then putting some workers on battle line makes even more damage. I didn't get any idea what to do at the moment. Panic blinded my decisions. I managed to build siege whisch was obvious outrange solution, and then lost him on 3/4 siege tech finished. Bummer. That leads to fourth mistake

Fourth, I didnt analyze the situation

Because of panic. My opponent was eager to stand his position as he wasn't have clear sight of my entire base. He just added cannon after cannon to get closer to my command. That means in his base he has nothing, all money was spent to finance this great opportunity. I forgot that cannon rush is win or lose situation, and that opponent base is defenseless. That is the risk. I should calmly lift up my CC, move to expansion, Lift my factory and barracks and choke him "in" my base, build 5 marines fast and run into his base. I would win. I know, because after torture and loosing almost everything I decided to go all-in with my 6-7 survived workers. They need some time to get there but even then, he was having some warp gates around a single pylon. Workers worked pylon out easily and warp gates died instantly. Then his 15 probes get in the game and I lost. I didnt have any ranged unit, nothing that shoots and that could make things more complicated. My all-in decision was waaaay to late, more of curiosity that any hope to win.

I am absloutely positive that if I lifted up everything and replace to expo, I could just ignore him, I would spare 4 marines and one siege. I would easily produce few more marines and counter rush.

I desperately need more practice in thinking of the game.
