so! as l was saying about the lambda MU. all in all l think you choked too much for that to really be a measure of your skill. i'll have to watch the other matches for that.
here's my take on the MU from fullscreen (assuming you read the rc vs la mu stuff, sakaku was spot on).
first of all. of course, block. why not? despite being a zoner she's not too threatening imho IF you know what to do. spike chaser and 236a are the main problems l have here, otherwise, ib swords, get your heat (and wind), and chillax until the lambda does something risky or tedious.
once you know what she'll do next:
IAD 5d/j 3d over 5d, 214[d] (has to be really early) and 236d
dash 5d under 6d
5b/236a/214a/214b/sj beats her 214[d]. best to just sj and be patient
you can't punish 236b or c, just ib them and start pressure
