I play in a deep stack 5 10 25 game. One of the regulars in the game 3 bets and squeezes wide (range is any suited Ace and hands like A10 off in addition to premiums). The game plays quite deep with 150 tto 300 BBs. For example, 5 10 25 (straddle hand), UG opens to 75, Villain 3bets to 250 from EP, I make it 700 from SB with AA, EP calls and Villain jams for 3100.

Post flop, especially in a HU pot, Villain c bets 90%. Turns and rivers are often barreled especially on scare cards.

What are some of the adjustments I need to make preflop and post flop?

Thanks!
