Defend your pocket pair aggressively on low boards and capitalize when the river completes your straight.

Flop Analysis

Checking is standard, but leading small is a high-frequency mix. This low board favors our flatting range which contains many more small pairs and connectors than the HJ opener.

Flop Analysis

We have a mandatory call with a gutshot and a pair that currently beats Villain's overcard bluffs. **Math:** We are getting 2.5:1 on a call, requiring 28% equity. With 60% equity against Villain's range, we are well above the threshold to continue. **Ranges:** HJ will barrel many overcards (AK, AQ) and backdoor draws here. Our 55 is a robust bluff-catcher that also has the nut-potential of a straight draw. --- > **Takeaway:** Don't fold mid-pairs on low boards to a single bet; you have too much equity against overcard bluffs.

Turn Analysis

The board pairing the 4 is excellent for us. It makes it harder for Villain to have trips and keeps our 55 as a very strong bluff-catcher.

River Analysis

We hit the straight on the river. While checking is a valid mix to induce bluffs, leading for value is also highly effective given our range advantage. **Ranges:** We have a massive range advantage (77% equity) because we have all the 5x and 75s that HJ lacks. Checking protects our weaker bluff-catchers, but betting ensures we get paid by Villain's overpairs or 6x. **Plan:** Since we checked, we are now in a trap-and-call or check-raise mode depending on Villain's sizing. --- > **Takeaway:** When the river completes the most obvious draw in your range, mixing between checking and leading prevents Villain from playing perfectly against you.

River Analysis

Calling is profitable, but raising is the superior play for value. We have the near-nuts and Villain's small bet looks like thin value or a 'blocker' bet that will call a raise. **Math:** Getting 4.1:1, we are never folding. However, by only calling, we leave significant EV on the table against Villain's 6x, 77-AA, or even A4/A2 holdings. **Sizing:** A large raise (100-140% pot) targets the top of Villain's range. Since the board is paired, we must be wary of 44 or 64, but those are rare enough that we must raise for value. --- > **Takeaway:** Don't just click call with straights on the river; look for opportunities to raise when Villain's range is wide and capped.

Note: Failing to raise the river with a straight misses significant value against Villain's calling range.
