Small bets fit merged ranges on high-card boards: the caller is capped and one-pair-heavy, so a small size bets a wide value range thinly and keeps their dominated hands in. Even a set bets small there — for balance, and because it earns more from a range that folds too much to a pot-size bet. Polarity, not just holding a big hand, is what sizes you up.
