Wow, he hadn't raised a single time preflop in over 100 hands? That's pretty funny, so he's gonna show up here with AA/KK everytime, pretty sure that guys like this one aren't doing it with AK even. He's basically playing with his cards face up, which is awesome for you. It's pretty likely he's stacking off no matter what flop (unless he has KK and A shows), and even though you've barely got odds
to setmine, MP2 might still call and bring more money to the pot. I'd call and hope a Q comes so I can take his whole stack on the flop. Oh, and I hope raising to 50c was a misclick. If you had raised to 85c your action would depend on his 3bet size, but if you weren't getting at least 8-1 implied odds it might actually be a fold, which is pretty ghey.
