Open AK, call the small 3-bet, mostly call the flop donk, and comfortably call the river shove with top pair.
Flop K92 rainbow, SPR ~2.6, and BB leads 7 into 31.5. Our top pair is strong but not invincible, and BB’s donk is weighted to strong hands. Solver prefers calling the donk with AK; raising is a bit ambitious and mostly folds out worse hands and draws while getting called by better.
Note: Flop raise is slightly too loose; calling the donk with AK keeps worse hands and draws in and avoids getting stacked by stronger Kx and sets.
Turn 7h, pot ~73.5bb, SPR ~0.8. After we raise flop and BB calls, checking back AK is reasonable—our hand is still ahead of a lot of 9x/2x/overcards, and betting mostly gets action from stronger Kx and sets. Checking back protects our range and avoids overplaying a strong but not invulnerable hand.
River 4d, BB shoves 56bb into 129.5bb. We’re getting ~2.3:1 and need ~30% equity; AK still has plenty of showdown value versus worse Ax and some bluffs, so calling is standard.
