Flop Analysis
Checking is the standard play here. While we have an open-ended straight draw, we are out of position and should let the preflop aggressor lead.
We must call the flop with an open-ended straight draw, but we can fold when the turn bet leaves us with no implied odds.
Checking is the standard play here. While we have an open-ended straight draw, we are out of position and should let the preflop aggressor lead.
We have a mandatory call with an open-ended straight draw, even against a large sizing that targets our range's elasticity. **Math:** We are getting 1.6:1 on a call, requiring 38% equity. With 8 clean outs to a straight, we have roughly 32% immediate equity, and our high-card value occasionally wins if the board runs out favorably. **Ranges:** LJ is polarized here, betting large with strong top pairs (A9, K9) and bluffs like overcards with backdoor draws (KJs, QTs). Folding an OESD this early would be a massive over-fold. --- > **Takeaway:** Never fold an open-ended straight draw on the flop for a single bet, regardless of the sizing.
The 2c is a total brick. We must check again and wait to see if LJ continues their aggression or takes a free card.
Folding is correct here because the effective SPR has collapsed, destroying our implied odds to chase the straight. **Math:** LJ's bet of 15.6BB leaves us with only ~5BB behind. We are getting 2.2:1, but since we only hit our straight ~17% of the time on the river, we don't have the direct odds to call. **Sizing:** By betting so large, LJ has effectively put us all-in. Since we cannot realize any more value if we hit our 5 or T on the river, the 'implied' part of implied odds has vanished. --- > **Takeaway:** When the SPR is low, draws lose value because you can no longer get paid off enough to justify the misses.
