Villian in this hand is a donkey. In a previous hand I raised pf with 44, and he called. On a 955 flop i c-bet, he minraised, and I called. Turn was an ace and I check/folded. Kind of stupid play by me, but whatever.

Now about 20 minutes later. In general, I tend to give a lot more respect and play more cautiously against good players when they take this line against me (lead, lead, lead), but coming from a donk, it really seems like he doesn't have a hand and is trying to pull a desperation bluff. I just don't think he would play a big hands this way. Thoughts?
