1) My first hand at the table. I have 8[d] 7[c] in the BB. Villain is UTG and he is a super rock at 15/5. I literally have 45 thousand hands datamined on him so that's a pretty firm read.

Flop ($9) 4[h] 5[h] 6[s]. There are 4 people in the hand so I just fire away betting $8.

Villain now raises to $28. All others fold.

What's our line and what's his hand range?

2) Different villain who is also rockish. He's in the 15/12 category. All full stacks.

I have Q[d] Q[h] OTB.

UTG donk min opens to $4. 2 callers and Villain calls in CO.

I repop to $16 . All of them call in classic Cake fashion.

Flop ($64). 7[s] 4[s] 2[d]. UTG moron leads $6, all folds.

Villain flat calls.

What is Villain's hand range and our play?

I think hand 2 villian isn't gonna be calling PF alot if you make it bigger but I have no facts to support this argument so meh.

I still think this is a raise because he could be calling with draws and shit like 99/88/66 and god only knows what. He'd be raising his entire range me thinks to isolate the limper or I guess he could get crafty and hope you raise then jam but cross that bridge when you come to it.

Hand 1 seems like villian has either a monster draw like 67hh or a set, I think I re-raise and get it all in, since neither of the those hands even comes close to folding.

Hand 2) I also like the raise, I think you could have raised a bit more PF but I don't think 16 is bad here(20-26 would have made your decision alot easier though). I really think you should raise the flop here, and agree with Shamdonks reasoning.

#2) I think he has any pocket pair. Some beat you and some dont. Also a chance of Ax of spades. Pot odds say you need to call.
