Pre Flop: (pot: 1.5 BB) Hero has 7♦ 6♦

fold, fold, Hero raises to 3 BB, BTN calls 3 BB, fold, fold

Flop: (7.5 BB, 2 players) Q♣ 9♠ 5♠
Hero bets 3.5 BB, BTN calls 3.5 BB

Turn: (14.5 BB, 2 players) 8♠
Hero bets 7 BB, BTN calls 7 BB

River: (28.5 BB, 2 players) 6♣
Hero checks, BTN checks

Preflop: I raise, hoping to steal. If I get called, the postflop decision is easy.
Flop: Gutshot on a rainbow flop. I cbet, hoping to make small pairs fold.
Turn: Completes a possible flush but gives me the straight. The small pairs decided to stick around. I bet to get value from top pair, some weird two parir or a slowplayed set.
River: With 3 ♣ on the table and 80% of a straight already there, I don't think a hand lower than 7x will call here. I check. IMHO, my hand is a bluff-catcher here.
