Villain: 55
Hero: JJ
Hero: AA
Villain: AQ (of spades?)
Rationale:
Hero should have monster made hand to re-raise villain who raised under the gun - AA, KK. Villain should have strong holding for under the gun raise but looking to improve due to checking - hoping for flush - AQs or AJs. On flop hero continuation bets at 50% nervous about 2 spades. A bit more confident on turn. On river hero has improves his hand and goes all in. Villain also has connected with A but misses flush so just checks. When hero raises villain likes pot odds and calls thinking more likely hero has KK. Would have expected more action from Villain with AJ so AQ.
Hero's range: AA, JJ, Ax, any flush- and straight draw
Villain's range: JJ, 99, 55, 44, Jx, Nutflushdraw
Hero Cbets flop 8BB and Cbets turn 22BB which seems like Hero wants to build a pot but also protects his strong hand against draws.
Hero: JJ
Villain: A :spade:T
