the first hand, definately checkraise the flop. the donk UTG+1 will possibly call 2 cold even (you want that) and if CO just calls, you are probably good, and if he 3bets, call down unless board gets scary.

hand 2, just call the flop 3bet, dont cap with top pair:tens with Q kicker after he raised preflop and is showing a lot of strength.

then checkraise the turn, if he 3bets, probably cap and figure him for JJ QQ KK AA.

then bet/call river.
