Why NOT to slow play a hand

Tourney play today. Not else more to say except, V would have probably went all in if I raised on the turn. Fatal mistake was not betting after the flop.

If villains a donkey you have to make a c bet if u raised pre, then check for a cheap showdown. Otherwise, fold to his raises, reraises…
You can get donk betted rather easy if ur passive post flop…you can also get check raised if you check the flop and bet the turn… my advice is… c bet the flop if u raised pre but dont c bet if theres an ace on the flop, that ace is good for peeling for the others after you…
