First spot)
200NL. Say we hold 77 on the button and call an open raise of $7 from a TAG in the CO. Blinds fold.

Flop($16) comes Q63r, he cbets and we call.
Turn($39): T, putting a FD on the board.
He checks, Hero ???

Do you bet or check here?

If you check, what rivers are you calling a bet on?

Second spot)
200NL with $210 stacks. We open to $7 OTB with 99. Guy who is not very aggressive and maybe a bit nitty post flop repops to $22 from the SB. We don't really know much about his 3betting frequency. We call.

Flop($46): 258 with 2 spades.
He bets $30, we call.

Turn($105): 2 offsuit.
He checks, do you bet or check? ($158 behind)
