Hand 1: If this is the first time i've seen him spazz shove like this i'd fold. Best case scenario against a relative unknown (at least in terms of showdown hands) is AsX, looks more like a 6 tho.

Hand 2: I fold this PF against an aggro SB that's playing tonnes of hands, it's not profitable to open 56o in that situation (especially given ur read about him not folding to c-bets). As played I'd swear alot then fold turn.
