Big pots

[The Iceman]

Your game seems alot more 'open' than mine so you might find my analysis weak tight.

Hand 1- check fold this on turn or maybe lead out (opponent dependent and this would be the last $ I pot into that pot).

Hand 2- I don't like raising this type of hand out of the BB against an unknown opponent. After that though you played it fine (though leading the turn works too).

Hand 3- Given your read this is ok.
