Theory shit for Headsup

You're facing a competent HU player. You play him for about 20 hands and realize that his strategy out of position is to 3-bet most hands he is playing, which you figure to be over 25%. You adjust by minraising, he continues to 3-bet to 3.5-4x. He has c-bet all the flops in which you called his 3-bets, you expect him to have a high c-bet percentage. Of the following which is the best counter strategy?

1) never calling 3-bets and using some kind of 4-betting strategy. I don't use this because i can't figure out how to make it effective but if you have one please lay it out.

Benefits: Villain has to make a preflop commitment while you do not (given 100-150BB stacks).

Cons: doesn't take advantage of his c-betting leak.

2) (note: do you think this preflop calling range is good? it's about 26% of hands) mostly call 3-bets with a range of 88+, J8s+, T8s+, 78s+, Axs, A7o+, K6s+, any two T or over (You may add 77-22 against certain types), occasionally 4-bet as a bluff or value depending on the type of player he is. Postflop, you are flatting most of his c-bets to keep your range wide, mixing in bluffs on the turn and river, and just basically playing late street poker.

Benefits: Keeps your range wide on all streets, forcing him into tough decisions oop.

Cons: Opponent usually sees all of his preflop equity. This i think may be a bigger deal than i originally thought.

3) same preflop strategy as 2. Postflop, mini raising or folding most of his c-bets while doing everything else a small % of the time when you see fit.

Benefits: Forces opponent to make commitment when he has a weaker range and has much less equity than preflop. Opponent doesn't see all streets.

Cons: ??????????

Ahhhhhhhhhhh, i always feel weird making posts like this cause HU is so player dependent. But i was playing someone like the player described in the OP today and i was using strategy 2, and i lost pretty hard. I was beginning to think that strategy 1 or 3 may be significantly better, given the bad commitment spot it puts my opponent in. Just post whatever comes thoughts come to your head from this post.

i just mix everything in together and hope to level the person when pots get big

What ive began to really like to do against non super good opponents is fourbet purely as bluffs a sparse percentage of the time (unless ive shown ive called a threebet with AA-QQ, AK because then I'm betting he;s going to shove over like crazy).

I think threebetting that much and cbetting every flop is such a gigantic leak versus anyone competent that you have to use the bulk of your range to call the threebets pre. Honestly, I think switching to minraising was a mistake. I'd just still pump it to 3-3.5x, 4 x if he keeps it up, and let him bloat the pot huge oop.

just open 50% of btns
