AA should mostly check flop and turn on T98x, then shove river on 5d after BB calls twice.
Flop T84 rainbow, we have an overpair with no club and no straight draw; BB has a slight range advantage but we still have strong equity. Solver leans toward checking this combo often, with some small and medium bets mixed in. The 7.6BB c-bet is a bit larger than the preferred small sizing and slightly lower EV than checking.
Note: C-bet sizing is a bit too large for this combo; checking or using a small bet performs slightly better.
Turn 9h adds straights (T9/J9/QJ) and improves some of BB’s floats; with SPR ~2, overpairs are often checked. Betting 14.7BB into 32.6BB is a bit too big for this combo and slightly over-invests versus a range that’s now more connected.
Note: Turn sizing is a bit too large for this combo; checking or using a small bet performs slightly better.
River 5d completes the 6-10 straight and BB’s range is now very strong; AA is still ahead of a lot of value and has strong showdown value, so jamming is the highest-EV way to get paid by worse pairs and strong draws that rivered.
