I am playing some heads up live with a friend. He limps arround 90% from the Bu and almost always limp calls when i raise. On the BB he defends 90% hands and never 3 bets at all. What would be an optimal preflop strategy against his play. I am struggeling against this cause his range is always so wide and never capped. I play 6max online and doing quite well atm but hu i rly suck and wanna improve.
