Hi Ian, me again! Plenty of comments on this one
slightly weird for black but I'm not sure it is a categorical mistake, still I wouldn't play it myself
I don't think this is passive, looks good for black to meYour variations at this point look odd, there are better things for white to do here
Leela is right, Q13 is best
are you sure you can tenuki? look at black P12, there is a strong attack to be made on that white group
strange, should be at L4, M4 or M3
should be one point to the left
you could also consider O3
I don't think this move is as bad as you think it was!
good! you were lucky to get this after you tenukid the first time though...
a better move in this area would be S12, much better endgame and possible eyeshape
is this the best move? read out white S3, can black actually cut there?
a good idea but would be better at G17, the top side is bigger than the bottom because of the low strong stone at K3
very slow, I would feel happier playing on the top or left sides
wrong side, this should definitely be at B5
not just sad but dead! After you protect at C6 black cannot live
you let black live! just connect at E2 and there's nothing black can do!
a bit close to your strength, D13/14 look better
don't worry, the kick is correct!
to 
any/all of these you should hane! why this move?
perhaps a cap at N8? Try and keep up the attack
Overall a very good attack, you used your strength well, just try to be aware of how to keep as much pressure on your opponent as possible 
A shape to remember, with this large knight move the vital point is at J18up tp white 128 I think there was little more you could have done against that black group, not sealing it in around
was the mistakewhite 178 - why peep when you can cut at L7?
white 198 - there is an interesting clamp tesuji at K6, try and see what happens if white plays here
at the end, you both pass, but there is still four points to make at J11!
A well fought game, you used your strength well and that attack in the centre definitely won you the game
Two points however, firstly always try to find the most severe move against a group you're attacking, simply letting him push from behind is good but not good enough when you can hane!
Secondly you played several peeps at the end when you could have cut, in general peeps are to be used sparingly, especially if there are cuts. Only peep at a cut if it gets you something worthwhile, simply adding a stone to an area you're already strong in isn't good enough!
:p
