You went outside of Amans habits rules on move 6 when you jammed up the queen side development
Per the habits it would have been d5 before putting your bishop on d6 I think
There’s some other moves in there that we’re outside of the habit’s rules but that was the earliest one I saw.
Stick at it - he’s clear in the series that if you follow the habits you will make some ‘wrong’ moves but it’s about building fundamental knowledge before getting into openings theory (at about the 1200 level)
I went from 400 to 1100 so far strictly following the habits guidelines (even though drunk playing sent me back down to 900…)
