I am playing a heads up home game against a known Villain. We are $300 deep and blinds are 1/3, no rake.

Villain is a crazy LAG big loser at full-ring, where his stats are 65/30 with a 3B of 10. He has a tendency to call draws regardless of the odds being offered postflop. (Addendum: his gambling debts caused him to lose his wife and children.)

In heads up, he never folds (0%) to a preflop raise. However, he only raises ~50% of hands when it is his turn to act. He bluffs a considerable amount on the flop and the turn but less so on the river. All his bets tend to be oversized (pot or more) regardless of whether it is for value or a bluff.

How would you

(a) adjust your range pre-flop on the button
(b) adjust your range pre-flop when not on the button
(c) adjust your bluff/value ratios and calling-down strength postflop?

If you give a man a fish, it eats for a day. If you teach a man to fish, he eats for life.

Download an equity calculator (many are free, literally no excuse to not do it). Use the calculator to determine what hands you have OOP that have 55% equity against his range. Raise those. Never limp. Call hands you have 50% equity when in position and raise those if he limps.

Good luck.

To add to Venice said, when dealing with a real LAG like this often your adjustments depend more on what the rest of the table is doing.

For example, in situation A with the LAG in a blind behind you on the button you would want to play some stupid wide range if it was heads up. But if the blind that isn't the LAG knows you have opened your range way up and is good he will know he can 3 bet bluff you more.

Also, playing the player comes into play. If the LAG has one stack and is done then you may need to take some bigger risks to get a chance at his money before he leaves. If he has deep pockets you want to keep him around and you may want to let him win some small pots along the way so he isn't getting crushed.

There's no "rest of the table", it's a HU game.

My bad, didn't read it close enough. I thought it was a heads up hand in a ring game, not a heads up game.

Heads up game is even more trival if villain actually has no preflop fold button. Raise all preflop with any hand with more then 50% equity wins in the long run. Playing the player still applies though because depending on how much of a degenerate he is that may get him to quit or rope him in to play more.

I think 10% 3b isn't too high tbh given his VPIP so i'd respect his 3b range a little bit

but don't make this a tricky thing, he's playing a lot hands pre, therefore his range will be wider than the average player entering the pot

this means we can certainly 3b him wide in position especially if theirs dead money out there

i would be 3betting him OOP fairly wide as well if his 30% pfr is high for the table

If he is super aggressive post flop then you could play a trapping style with strong hands or maybe bluff catch in certain spots,

If he's a calling station post flop and just likes to gamble and put money in then value bet him to death and don't try and force bluffs against him
