Zeebo: No one can ever fold a full house.
My own corollary to Zeebo Theorem is Bugzo, which states:
Bugzo: Hitting your full house makes you blind to reading your opponent's hand.
Here's an example of Zeebo/Bugzo from yesterday's short session I played:
Merge, $0.50/$1 No Limit Hold'em Cash, 6 Players
CO: $149.80 (149.8 bb)
BTN: $191.61 (191.6 bb)
SB: $102 (102 bb)
BB: $200.75 (200.8 bb)
Hero (UTG): $159.73 (159.7 bb)
MP: $101.50 (101.5 bb)
Preflop: Hero is UTG with 5♠5♥
Hero raises to $2.87, 4 folds, BB calls $1.87
Flop: ($6.24) J♣5♣6♣
BB checks, Hero bets $4.68, BB calls $4.68
Turn: ($15.60) J♥
BB checks, Hero bets $11.70, BB calls $11.70
River: ($39) A♦
BB checks, Hero bets $29.25, BB raises to $87.75, Hero raises to $140.48, BB calls $52.73
Results: $319.96 pot ($3.00 rake)
Final Board: J♣5♣6♣J♥A♦
BB showed J♠A♠ and won $316.96 ($157.23 net)
Hero showed 5♠5♥ and lost (-$159.73 net)
I was destined to lose money in this cooler-hand, but I think I could have at least saved the $52.73 on the end by just calling behind. Meh. My original read was the guy was slow playing a flopped flush. Zeebo kept me from folding. Bugzo kept me blind to any other possibilities. Sigh.
All-in for now...
