After flop check-raise getting called, the 4s turn gives us a strong straight; we should bet big, around 125% pot, to maximize value from worse straights and strong draws.
On T65r we have an OESD plus backdoor hearts, but no made hand yet. This texture is very draw-heavy and connects well with BU’s opening range, so checking our entire range is standard. Solver prefers checking this combo almost always, with a small amount of small leading as a mix.
After we check and BU fires 2 into 6.5, we’re getting a great price to continue with a strong draw. Solver likes mixing between calling and raising here, with a slight preference for a larger raise size (around 1.2x pot) to apply real pressure to BU’s one-pair and weaker draw holdings. Our 6bb raise is a bit on the small side but still works well as a semi-bluff.
The 4s turn completes our straight (8-high) on a board that’s now T-6-5-4. After BU calls our flop check-raise, their range is weighted toward 7x, sets, and strong draws. We should bet big here, around 125% pot, to extract maximum value from those worse straights and strong draws. A smaller bet like 14bb leaves money on the table versus a range that’s very likely to pay off a big bet.
