As a Maxx player myself, I struggle a lot when the corp systematically does the following (usually some sort of NEH or other fast advance type corp)
Double Ice HQ (taxing outer ice, cheap ETR gear check inside ice)
Double Ice R&D (taxing outer ice, cheap ETR gear check inside ice)
Fast advance to score out of hand (single ETR ice on remote can do it if you're using a sansan to assist with that as that turns off eater)
OK I know I'm not the best player, and I may be doing this completely wrong, but there is no way I can generate enough cash to get consistent accesses using eater/keyhole/wanton destruction, and also trash 'must trash' cards like sansan.
DDoS avoids the outer ice for a couple of turns, and if I'm really lucky, I can nuke out a few select R&D picks using keyhole, or maybe dump your hand using wanton using eater to get past the inside ice, but once both ice get rezzed (I cant have permanent DDoS) I can't afford to run them consistently.
Moving on in the future, I need to consider how I get past this problem since this sort of deck comprises a significant part of the meta, but that's a question for a different thread.
