Best play: Raise
Why
Hero is SB with KQs versus a BTN open, and since the SB has no free check, the live choices are 3‑bet, complete, or fold. KQs is a premium suited broadway that blocks KK, QQ, AK and AQ, dominates the BTN's worse K-x and Q-x, and flops top pair or strong draws constantly. Playing 3‑bet-or-fold from the SB, this hand is a clear value raise.
Key idea
From the SB the only ways to continue preflop are complete, raise, or fold — never check. KQs is strong enough to be a value 3‑bet in a 3‑bet-or-fold blind strategy, taking the lead rather than flatting out of position.
Common mistake
Selecting 'check' as if the SB had the BB's free option — the SB cannot check preflop. Flatting KQs out of position also under-realizes its equity compared with raising for value.
