Small hand small pot - big hand big pot. TPTK isnt a big hand so you need to control the pot size and keep it small above all other concerns.

When I have a one pair hand I usually decide I have to skip a street to keep the pot small, now that can be the flop or the turn but if I'm betting both the pot is getting too big for the strength of my hand.

For example in hand 1. you could have easily checked behind on the turn keeping the pot small and even if he had the trips/flush you would only be calling a suck bet on the river, not losing your whole stack.

Letting a card come off to beat you in a small pot isn't a big mistake, but stacking off is.
