$2.5M Bad Beat Bonanza at Casino du Lac-Leamy Shakes Poker Canada

Recently, Casino du Lac-Leamy in Gatineau, Quebec, became the talk of the Canadian poker world. A simple $1/$3 no-limit hold’em cash game triggered a CAD $2.5 million (approximately USD $1.81 million) bad beat jackpot, which became the second largest such jackpot in poker history.

A bad beat jackpot is a rare prize in poker when a losing player gets coolered to the first degree. It is awarded when a powerful hand, typically quad eights or better, loses to an even stronger one. I've only seen these jackpots in hold 'em as that is the game least likely to produce these rare hands, due to limited hole cards.

Details regarding the hole cards this week aren't broadly known yet. But in a previous case, a losing hand was four-of-a-kind tens while the winning hand was a king-high straight flush. The loser had pocket tens for hole cards while the winner of the hand held Qc9c, as reported on at Poker News.

Here is some help on understanding Bad Beat Jackpots as per Phil Galfond. They can be called "BBJs" in poker lingo.

The payouts for BBJs can vary, but standard bad-beat rules are as follows: 40% to the player with the losing hand (making him the winner?). Then, 20% went to the winner (i.e., the player with the best hand), 20% split among players at the table, and the final 20% distributed to others in the poker room (ie. like players at another table).

Casino du Lac-Leamy, perched along the picturesque Ottawa River near Ottawa, is a top-tier gaming venue with a stellar poker room, praised for its lively atmosphere, modern facilities, and exceptional staff. The jackpot builds on Canada’s streak of massive bad beats, like a $2.2 million payout at Quebec’s Playground.

I'm not much of a mathematician (literally no math courses after high school), so I decided to defer to AI calculations when it comes to the chances of this bad-beat jackpot happening (source: Grok on X). If one player is holding two red tens and another is holding the queen-nine of clubs, Grok says a bad-beat jackpot eventuating has chances of 1 in 13,483.

But I would say the chances are much longer based on how the hand plays. Grok seemed to factor in the number of boards, after the river, that produced both quad-tens for one player and a straight flush for the other. However, let's keep in mind the chance of a fold occurring and how it lengthens the odds.

For starters, if pocket tens puts a heavy bet in preflop, a lot of players might simply fold a suited queen-nine. But even if they get to the flop, then there would be some boards where the quad-tens come on the flop and the ensuing betting is so heavy that they produce a fold out of the Q9-suited, that player not knowing - and never knowing - that the turn and/or river would lead to the bad-beat jackpot.

Grok said that there were only 127 boards out of 1,712,304 possibilities that could produce the bad-beat jackpot. I don't fully trust AI, but taken as food for thought, as opposed to omniscient math, the calculation still underscores the rarity of such a payout.
