I like to see a flop here.

Despite being a maniac his hand did have some value. With your read you can assume 1/2 the time he has top pair or better here.

This flop sucks because the other cards are so low, you have no hidden outs if he has a King, his kicker, even if it's K8 plays and you lose. I think it's best to fold and keep exploiting your much larger edges (like your previous hand)
