Stack sizes
UTG - Banker (2k) - Big spot in the game, loose passive whale
MP (irrelevant)
HJ - Owns a dumpster company (2k) - Competent aggressive opponent but he has money to burn so he calls too much, bluffs too much etc...
CO - Owns a roofing company (3k) - Biggest spot in the player pool who straddles to 20/30 every chance he gets.
BTN - Hero (1.5k) - Viewed as solid winning player
CO asks me to BTN straddle and I oblige.
Hero is dealt 8

Blinds fold, UTG limps, MP limps, HJ limps, CO limps, BTN checks
With the CO in the hand I can't raise here since nobody is folding. Pretty clear check imo.
Pot is 50
Flop is A

UTG bets out 20, HJ raises to 65, Hero...
