Preflop and turn are fine, but once we block-bet river and get raised, our two pair is a bluff-catcher that should fold.
On this paired, very favorable flop after 3‑betting, the default is a small c‑bet; checking is defensible multiway, but we give up a strong range and nut‑draw equity realization edge when we let it check through.
Note: Checking on a board that massively favors our tight 3‑bet range over two capped calling ranges misses a profitable small c‑bet with our backdoor nut flush draw.
Once we pick up the nut flush draw on the turn with a low SPR, betting is good: we leverage fold equity versus one‑pair and underpairs while having strong equity when called.
With two pair and SPR ~1, a river bet is reasonable, but the very small size under‑realizes value and invites raises; a larger, more polar bet or a check makes our range and decision clearer.
Note: Using a small block‑bet here with a strong but non‑nut hand exposes us to tough raises instead of cleanly realizing value or pot‑controlling.
Facing a big raise over our small river bet, our two pair functions as a bluff‑catcher; given how many full houses, trip tens, and straights villain can have after calling turn, folding is preferred to needing ~31% equity and hoping for bluffs that are hard to find.
Note: Calling the large river raise over‑values our hand strength on a paired board where villain’s line is heavily value‑weighted and we need a high bluff frequency to justify continuing.
