Unknown player 3-bets you preflop.
Population tendency: Under-4-bet, so they're strong.
Default action: Fold marginal hands, only continue with premium.
Once you have reads: Adjust if this player 3-bets light.
Population tendencies are your baseline exploits. Most players under-bluff rivers, over-fold to 3-bets, and don't defend enough. Start with population adjustments and refine as you get individual reads.
