Flop Analysis
Checking is the preferred play here. While we have an overpair, this board texture is significantly better for the Button's condensed calling range than our wide HJ opening range. **Ranges:** The Button has all the sets (55, 44, 22) and straights (A3s, 63s) that we often lack or mix. Our range contains many high-card whiffs (AK, AQ, KJ) that need protection, so we check our strong-but-vulnerable hands like 77 to keep our checking range robust. **Board:** This low, connected runout creates a 'nut advantage' for the caller. Any 3 or 6 on future streets is highly dynamic, and by checking, we control the pot size while preparing to bluff-catch or value-bet safer turns. **Sizing:** If we do bet, solver prefers a massive overbet (130% pot) to polarize our range. Our small 50% pot bet is a 'range bet' sizing that doesn't apply enough pressure to the Button's many pairs and draws. --- > **Takeaway:** On low, connected boards that favor the caller's range, check your medium overpairs to protect your air and realize equity safely.
Note: Betting small here is a slight mistake; the board texture heavily favors the Button's range, making a check or a very large sizing more effective.
