fireproof vs Boidhre

by Boidhre
One of our newer members played a game on 6 stones with me on Dragon Go. I tried to play moves to see how they would react as much as play to win, I'm not sure if this is a good approach or not. Fireproof said he would welcome comments from other players on our game and asked me to create this thread.

Usually the best moves are those that get ahead of the opponent or catch up. Getting too far ahead or too far behind is often inefficient, especially early in the game. Here Black gets two stones ahead in the top left. Not necessarily bad, but probably not best. See variation.]

Skydyr, Black can play E18 instead of E19, in your first ko variation no?

Good point. That's what I get for going through these quickly.

Yes, White is just dead with E18 on the 119 var, and the alternative suggestion on 121 is going to drop liberties I think (and still be dead). Some excellent suggestions for black midgame though

Thank you all for the comments - I'm still going through them (slowly!) in between Dad-responsibilities.
