PF: OK
F (48): SPR is ~6. $25 Bet is fine, although a bit low for me.
T(123): $70 Bet is fine. We've put in 38% of the effective stack. BTN shoves: $174 to call to win $437 (2.5:1 or 28%). BTN is tightish-passive, over how many hands? Only hands that beat us are JJ, 88, 55, and AA with JJ and AA being unlikely. Could be doing this with AdXd or 9d8d but does a tightish-passive do this? Could be doing this with A8 or A5.
Jesus, this is tough one. I always like to think in these spots: It's hard to flop a set
I think we need to call.
