Hand 4: Q7cc would be one of the 7x hands I'd vbet for a variety of reasons, but x/c is fine.

AP, it's pretty close I guess. We should have a lot of Ax here, but the price is good and the river is so blank that third pair still might rank high enough as a bluff catcher. I'm way understudied on SBvBB and just approximate based on analogous spots, so I probably shouldn't even bother giving a certain conclusion, haha.
