Why the river fold in hand 1?

You now beat QJ with the board pairing. Getting 17-1, you have to be absolutely sure you are beat and I think there is enough doubt to call.

I need a really good read to fold Hand 2. You did not have such a read so given the pot size I call down without a bad conscience.

I am guessing that you are probably experienced enough to make a big laydown in a big pot with a good read. I am not. But even then, I would not fold these hands as I believe there is still doubt in hand 1, and the read is not solid enough in hand 2.
