in hand one, this is JUST on the edge of hands i'm generally mucking preflop in this situation. Because it's six max i might raise it if it's suited, otherwise it's a "win a small pot, lose a big pot" type of hand if you get called by someone who has position on you.
imho, hand two could not be played worse. not nitty, just mindlessly. obviously you already know that you shouldn't limp this hand, as played ...well i haven't been in the situation since back when i had no clue so i don't really know if the limp call here is right, but i'm ditching it 'cause your OOP w an already marginal hand facing a raise. NEVER donking this. i assume you did this as protection against the SD, but i'd let him come to me, and i'm probably only c/c'ing at that
