NL10- a few line checks

[youngmachetes]

a lot of turns are bad for sure in hand 2. c/r'ing is prob. worse than bet/folding, but i dunno. i decided to call flop with the intention of leading a safe turn, and i deemed the 8s safe enough. we checked it down and nit showed KK. i should've shoved the river prob. (as a bluff). i thought he might show up with Axcc or maybe even AK, and i didn't think he would try to push me off my hand therefore allowing me to show down. any thoughts on hands 1 and 3?
