Best play: Bet 33% pot
Why
Principle: thin value targets the weakest part of villain calling range that still beats a check. Applied to AJ TPGK on J84-7‑4: small sizing keeps underpairs and dominated Jx in for one more bet without scaring them off. So: bet 33% pot — overbets here only get called by hands that beat us anyway.
Key idea
For thin value with a medium-strength made hand, size small so worse hands keep calling instead of folding.
