Hey mickito,
you are doing some really nice work there.
I am not sng player neither HU player so its interesting to see dynamics here. Well here are my thoughts which might not be right for SNG HU game but still....
Well what i want to say is something about limping. OK in cash game somehow we can say limping is acceptable in really rare cases. I don't know if it is the same in SNG game. If you decide to limp with "playable" hands you have to put also some better hand in your limping range otherwise all limping hands will look very weak. If at some point villains exploit that you gonna have some troubles.
As said i am not familiar SNG game and thus i cannot say if liming is good or not. I would suggest you to post some limping hands in HE board so you can be sure you are doing things right. I also realized you post entire video in HE board. I hope judges will evaluate it for you. If not post individual hands.

Good luck.
