1-3, yawn, these are coolers and i'm pretty sure you know they are coolers.
well you have to remember that going broke with two pair in a limped pot is a worse mistake than going broke with two pair in a raised pot
so as played I give serious consideration to folding that river
this is because if he had just a ten, he'd be very concerned about the J and Q
if he had a piece and the J or Q improved him he's beating you with a better two pair

similar logic applies to the last hand
while he is pretty short, the flop is multi-way which means the requirements for winning the pot go up
1. there is less bluffing because people are more afraid of getting called
2. someone already expressed interested in the pot
3. someone else said it's their pot and told the first person to fuck off
