Hand 1
One shortstack donk limps, I make it 18 in the CO with [Qh] with a full stack, Button who is good and has a ful stack calls, as does unknown BB with 272, UTG folds.

Flop [Tc][Js] (60)
BB shoves for 256, hero???

Hand 2
Same shortstack donk limps UTG , I make it 16 with [5c] (725 stack), same guy as before OTB, has lost some pots and pushed for his last 52, SB with a 950 stack calls, BB and UTG folds. I call 36 in the 128 pot.

Flop [6s][7d] (165)
BB bets 150, I have 670. Shove or fold?
Calling isn't really an option is it? (pot would be 465, and I would have 520 left, and a lot of scary cards killing me or the action could come on the turn?)

The more I think about them, the easier these hands are.
What could button have in hand 1, that could scare me?

I called in Hand 1. Button folded. Villain had JT, and I think I had 48% equity. The turn was an 8. And so was the river. So I both go the straight, and a higher two pair.

I showed in hand 2. He called with . Button had . I held up. Biggest pot I won.

I do not think I vary my PFR depending on the strength of my hand. More on position and some randomness. But I have observed that from some opponents. There are a few where I know that a minraise PF is a low PP, as an example.
