New to HU, playing against a super aggressive donk NLTRN

First post. Hopefully it isn't too terrible [img]/images/graemlins/tongue.gif[/img]

I am pretty new to heads up, as I usually only play 6max and mtts.

Anyways, a friend and I have recently been playing some HU matches, stacks start at 1500 with 10/20 blinds going up every 8 hands.

Some thoughts on opponent:

He is super aggro, in the early stages he will almost never raise except for a minraise. In the middle stages he is raising probably 70% from position and about 50% from the bb if i limp.

Loves to donk the river if he doesn't hit and checkraises the river with a wide range.

Doesn't raise AA,KK,AK,QQ,JJ,AQ pre.

Almost never folds to a continuation bet and floats alot.

Makes a continuation bet 80% of the time, but if he flops the nuts he will usually check one or two streets before betting.

This is probably a pretty easy opp, but it can get really frustrating in later stages when the blinds start to matter.

Thanks in advance!
