Well Blom didn't rep rly much of value w c/r as well as Munns w raise back since if Blom c/r range is mostly bluffs it doesn't rly make sense to raise back w Ax here (especially as weak as A7 since it should ISO him against stronger hands that Blom is repping and fold out his bluffs
) obv blom being blom realized that and since he's typical Swedish lagtard he went all in.
Anyway, don't think that his play is super duper spew overall, tho vs random live donk it def is, you can see by Munns reaction after blom goes all in that he just makes random moves without any plan whatsoever.
