Both these hands hapenned on the bubble (19 players left, 18 cash. Min cash = 1.4k vs 530$ buyin (pretty big mincash).

Hand 1: I was like 12th/19 with roughly 4 players under 100k chips. Shortest stack had like 50k chips. Any ways I can avoid bubbling in this hand?

Hand 2: Happened about 10 hands before hand 1, on bubble also. Should I have called the river? his smaller bet size on the river looked like he was trying to get value from my mid-strength hands
