99 against maniac

[Dalek]

If you re-pop the flop and he shoves you fold for cheaper than calling down to the end.

If you play passively against aggressive opponents you will have no idea where you are and end up being in bad positions like you are now.

Re-raise flop.
Fold or re-raise turn. I probably re-raise a maniac.
Fold river.

Your line was bad, IMO. His aggresion turned you into a loose-passive player which is never good.
