Aggressive players that keep winning...

[JDalla]

I have a recurring problem with a certain player that I often play heads up who is insanely aggressive. The first big losses I attributed to running bad, but at this point I have lost thousands in 10/20 to this guy and I can't figure out what is going wrong.

The guy plays by these guidelines:
1) Cap preflop if I 3-bet, or if I limp raise
2) Cap any draw on the flop and turn, including any gutshot
3) Always bet to a check
4) Showdown A hi or better
5) Bluff a lot (and 3 bet most bluffs if raised).
6) Never limp, raise 95% of starting hands, fold bottom 5%.

The guy literally plays by these guidelines, yet somehow I can't seem to beat him. I've tried limp raising A7+ (he autocaps something like K2o here).

The only explinations I can think of are
1) I've just been running bad against him many times in a row.
2) He wins enough small pots and rivers enough to counteract his massive payouts of every board I hit.
3) He gets paid off really big because of his bluffs?

I could see how (3) is a good situation for him, but I the problem is he never makes laydowns so I get paid off everytime I make a pair and he has Ace high...

Any insight?
