Flop Analysis
Checking is the preferred play here. While we have an open-ended straight draw, this board texture hits the caller's range very well, and checking allows us to realize equity or check-call.
Folding an open-ended straight draw on the flop for a single bet is a significant mistake, especially with 20BB effective stacks.

Folding here is a major error. We have an open-ended straight draw (OESD) and two overcards to the board's pair, giving us plenty of equity to continue against a 60% pot bet. **Math:** We are getting 2.7:1 on a call, requiring roughly 27% equity. With our OESD alone, we have 8 outs to the nuts (approx. 32% equity over two streets), which easily clears the threshold for continuing. **Ranges:** CO's range includes many hands we are currently ahead of or flipping against, such as flush draws (As9s) or gutshots (Kc9c). Even against their value range like trips (Tc9c) or two pair (KcQh), we have significant drawing equity. **Plan:** By calling, we can evaluate the turn. If we hit our straight, we are in a perfect position to check-shove or lead for value given the shallow 1.67 SPR. --- > **Takeaway:** Never fold an open-ended straight draw to a single bet on the flop when the SPR is low; you have the direct odds to continue.
Note: Folding an OESD on the flop is a massive equity gift to the opponent; we have the required odds to call or even check-shove.
