The epitome of results oriented thinking. Yes, everyone's laughing at Blom here, but hail Durrrr as a "genius" when he does this with hands a lot worse than K2s.
Blom was in a very late position, and made a loose raise against an amateur player. It's not a bad hand for a LAG-gish move here. It can flop 2nd nuts (1st nuts if the Ad rolls off). The most questionable play here was that re-raise from A7-off. That's not a hand I like to fool with, especially behind a raise. Flatting would be questionable, as the only safe flop is 77x. An A7 flop is likely to leave you with a dangerous top and bottom two pair. Top Two puts straight draws on board. Pairing aces leaves you with a weak kicker, and pairing sevens is nothing to get excited about, even if it's the top pair that leaves a lot of overcards that can drop on the turn, and ESSSSS-loads of straight draws, and made straights.
Two aces roll off, including the Ad, giving Blom a back door to the A-high flush. Since there are two aces on board, he would have no reason to expect Munns might have one, but he could certainly represent one by leading into that board. So Blom was trying to rep the hand his opponent happened to have, got called, missed his backdoor flush. Oh well SUX to be him.
Still, he could have a lot of hands that beat Munns' seven high. I don't know if Munns had a good read here, or if he played it like any rec-fish: "Me has tree aces! Me calls!" without regard to whether or not Blom just might have had a Big Slick, which he could easily have had.
If it had gone the other way, Munns decided Blom had a Big Slick, or related hand, and folded to the AI, would they still be calling this the most ridiculous bluff? Or would they be calling it a genius bluff?
