Why
Hero is SB with JTs versus a BTN open, and because the SB has no free check preflop, the choices are 3‑bet, complete, or fold. JTs is the most connected suited broadway, with maximum straight coverage plus flush potential, so it realizes equity well even when called — an ideal bluff/semi-value 3‑bet. Playing 3‑bet-or-fold from the SB out of position, raising is the correct action.
Key idea
From the SB, checking is never available preflop — only complete, raise, or fold. Connected suited hands like JTs are prime out-of-position 3‑bet bluffs because their straight and flush equity realizes well when the raise is called.
Common mistake
Choosing 'check' as though the SB shared the BB's free option — it does not exist for the SB preflop. Passively completing JTs also wastes its strong realization and the initiative a 3‑bet provides.
