Preflop defend is loose but playable; postflop line is generally solid until the river, where betting non-all-in and then calling the check-raise is a big leak at NL200.

Flop Analysis

Calling flop is mandatory: we have a strong flush draw on a paired, high-card board, in position, and we’re getting excellent odds against a polarized c-bet range.

Turn Analysis

Turn is a mixed spot where checking is slightly preferred with our exact hand; if we do bet, the solver wants a small stab rather than the large sizing we used. **Ranges:** After SB checks, ranges are closer: SB still has AA/KK/QQ but also many give-ups and medium pairs; our range carries plenty of Qx, Kx, and flush draws. With T7s we sit at the very bottom of our continuing range. **Sizing:** Solver leans on a small ~⅓-pot bet with bluffs like our draw to deny some equity without bloating the pot; our ~⅔-pot sizing over-invests with a weak draw and makes it too easy for SB to continue correctly with strong hands. **Plan:** Checking keeps our range protected and allows us to realize our flush equity cheaply; if we bet small and get called, we can still comfortably value bet rivers when we hit and give up more easily on bricks. --- > **Takeaway:** With weak draws on paired, wet boards IP, favor checking or small bets over big stabs that sink too much into pots where villain’s strong hands continue.

Note: Turn bet is okay in theory as a mix, but sizing should be small; using a large size with a bottom-range draw is unnecessarily spewy and lowers EV.

River Analysis

Once we make a flush on a paired board with SPR ≈1, the solver wants us to shove rather than leave chips behind; our ⅔-pot bet under-uses our nut leverage and invites awkward raises. **Ranges:** We have all nut flushes and a lot of Qx; SB has full houses (QQ, KK, some KQ) but far fewer flushes, so our range is heavily value-dense here. Our T-high flush is mid in our flush region but still strong versus SB’s overall range. **SPR:** With ~83.5BB behind into a 77.2BB pot, SPR is ~1; in GTO, strong but non-nut hands get pushed all-in in these spots to maximize value, deny equity from hands with a spade, and prevent giving villain cheap bluff-raise room. **Sizing:** Shoving makes SB’s bluff-raises impossible and forces his Kx and lower flushes into a hard call-fold decision; our smaller 51BB bet leaves a back-raise stack and effectively caps our line, enabling SB to exploit us with a polarized raise range. --- > **Takeaway:** With strong but non-nut hands and SPR ≈1 on the river, simplify by shoving rather than betting small and leaving room to be raised.

Note: Not jamming river with a strong flush at SPR ≈1 gives up value and exposes us to a tough spot versus a check-raise.

River Analysis

Calling the river check-raise is the big leak: our T-high flush is too far down in our value range on a paired, 3-bet pot board where population almost never bluffs. **Ranges:** SB’s check-raising range here is heavily weighted to full houses (QQ, KK, some KQ, maybe slow-played AQ) and higher flushes (AsXs, JsXs, 9s8s etc.). Our specific hand doesn’t block boats or nut flushes and blocks only very low flushes, so we mainly unblock his value range. **Math:** We’re getting ~2.5:1 and need ~28% equity, but versus a realistic SB river x/r range at NL200 our equity with T7s is far lower; GTO might mix calls with some better flushes and strong Qx, but T7s is a clear fold exploitatively. **Exploits:** In this pool, river check-raises in 3-bet pots on paired flush boards are massively under-bluffed; folding all but our very best flushes and full houses is highly profitable long-term. --- > **Takeaway:** At NL200, treat river check-raises on paired, flush-completing boards as ultra-strong and fold mid/low flushes, even when pot odds look tempting.

Note: Calling the river check-raise with a low flush on a paired, 3-bet-board is a clear overcall versus a value-heavy, under-bluffed line.
