Turbos, we are roughly equally stacked with 1500 chips, blinds are 40/80 (and increase every 5 min). Opponent is shoving on button roughly 2 out of 3 times. What's my (minimum) calling hands at 40/80? What about at 50/100, and then 60/120?

I folded 22 when at 40/80 because I didn't want to flip against such a fish (flip or be crushed if he had a pocket pair).

It's a mistake not to call 22 preflop.

You should call with 22+, A2+,K2s+, K6o+, Q6s+, Q8o+, J8s+,JTo+,T9s.
These have at least 50% equity against villain's range. You obviously want to call with 50% equity.
Wider for 50/100 and 60/120 of course.

You should use pokerstove, but you should still give more value to 22+ than T8+ if you use ranges. Pokerstove only approximates ranges.

Thanks. I guess my only issue was with flipping. Because villain is so bad is it worth our time to sit and wait on stronger hands to call his shoves with? Suppose I pass up calling with 22, but get a big ace 3 hands later? Ofc I could go card dead too. Interestingly enough, when villain was shoving, I was getting the bottom of the pile, i.e. 82o, J3o, etc. It was a strange spot b/c I obv couldn't bluff back (since he was shoving). I just had to take it and it felt helpless tbh. lol

You are worrying about shortterm results by not calling with 22, think about your longterm expectation, you will loose lots of money in the long run if you dont call with 22 in these spots.

You dont know if he Keeps playing this Way in The future. If you are sure that he will, then call Tight.

Villain is playing bad, don't respond by playing bad. Remember the 120 dead money, you have equity. And if he is shoving 65% of the times, it is likely he isn't shovin strictly the top of his range, he probably even shoves 23 or 35 if he feels like it.
That's why 22 will have better equity.
When you input 22 into a preflop equity calculator it will assume opponent's 65% is composed of entirely the top of his range, AKA villain never pushes with T2, but always pushes with J2. Villain being bad, gives us more reason to believe his range is composed by at least ATC with a frequency distribution that equates to something near 65% of shoves. This "real" range fares worst against our 22 than the 65% range pokerstove uses.
