I agree with everyone else. Hand one is fine, although calling and raising less are both reasonable options. I think pushing here is probably best in most spots because playing JJ postflop against opponents with wide ranges is often tough. Hand 2 is definitely a call. If you had 1k and there was a shorty with 100, then this fold would make a lot more sense. Here, you're way ahead of any even slightly reasonable pushing range and there are no weird stack size considerations to think about.
