Flop Analysis
While we have an overpair and an open-ended straight draw, this board is much better for the caller's range than ours. A small sizing is required to maintain our range advantage. **Sizing:** We bet 35BB, but the solver prefers a small 15BB (25% pot) block. Our large sizing isolates us against the top of BU's range (straights and two-pairs) while forcing out hands we dominate like TT or weaker AK combos. **Board:** This texture is highly coordinated. While we hold AA, BU has all the T9s, KQ, and QJ that flat a 4-bet. By betting small, we allow ourselves to continue on more turns and keep BU's bluffs in the pot. **Math:** We have ~66% equity against BU's continuing range, but that equity is fragile. A small bet realizes our equity more effectively while keeping the pot manageable if we face resistance. --- > **Takeaway:** On broadway-heavy boards in 4-bet pots, use small c-bet sizes (20-30% pot) to protect your range and keep dominated hands calling.
Note: Sizing is too large; a small 25% pot bet is preferred to keep BU's range wide on a board that hits their calling range hard.
