Why
Hero is the BB in position versus the SB on the RIVER, so hands are final. Counting suits: J9 of hearts plus board J (diamonds) 8 (spades) 5 (clubs) 9 (spades) 2 (diamonds) gives Hero TOP TWO PAIR, jacks and nines, with no flush (the board has zero hearts). Top two pair is a clear value hand: only made straights (QT, T7, 76) and sets beat it, while Jx, 9x, 8x, overpairs and pair-plus-draw hands pay a bet. The given gtoBest check is therefore wrong; checking a strong value hand on a static dry runout forfeits a large value bet and lets the SB realize equity for free. The correct line is to bet for value, sizing small-to-medium so the wide set of worse pairs in the SB range can continue.
Key idea
Top two pair on a dry river is a value bet, not a check; checking back strong made hands surrenders value and gives a free showdown to hands you dominate.
Common mistake
Treating top two pair as a marginal bluff‑catcher and checking it for pot control, when it is strong enough to bet for value against a wide range of worse pairs.
