Two hands vs "LastLazyGun running good", 5/10, semi-deep

[ocklind]

LastLazyGun is running at 19/14 and has been hitting good and getting paid off this session. Haven't really played w/ him that much before, just know hes tight and makes some big moves sometimes(seen it only a few times though)

Hand 1:

Whats my river move and could I have played the hand in a better way?

Hand 2:

What hands that beat me on the flop does not raise? It seems to me that he is peeling w a pair, a flushdraw would've raised here? A flopped str8 could just call here.

So whats my move?
