A couple of questionable pushes given 15+ BB (6 max, 30 and a 20)

[BarryLyndon]

30+3: Blinds 25/50

1. Hero (750), CO
Button (983), Button
Villain, SB (2200)
BB (2600)

Villain is exactly the type of player to call with a lot of broadways, low pairs, even a weak ace. He's terrible.

Fold to Hero who pushes with 88 ?

2. 20 + 2, HU ITM

Blinds 60/120

Villain (2900) SB
Hero (6100), BB

I've been very aggressive thus far, pushing a lot with a big stack throughout. Villain has been passive / limpy, but could be getting sick of my pushes and call me down light. I have been using this big push here because so many weak aces or KQ, KJ have been coming for the ride. And if I raise, I know he's going to call, and when he calls, I'm going to be OOP in a [censored] spot.

Villain limps, Hero with As10s pushes.
