Cool,
Your explanation for the K7 hand makes sense if you can get away from a heart turn.

Giving two players a free card when you only have TPGK on flop, & given that you would be unlikely to get away from top pair if they hit -still not good , (just my opinion) & if they folded to your c-bet that would be a great result.

last hand, fine explanation, but that hand that position is throwing away money
regardless I think.
Good luck at the tables, keep posting.
What are your preflop stats?
