I love HORSE tournaments. What I observe is that just about every player will be weak in at least one of the 5 games and I'm at least competent in all of them. I have two WSOP cashes in HORSE (You can read about my 28th place cash in the 2008 WSOP $3,000 HORSE if you are interested) and have won a bunch of smaller HORSE events online. Pokerstars used to have a $109 buy in HORSE tournament every day with a $5,000 guarantee where we'd often have either 48 or sometimes 40 players creating an overlay. I had one run where I won it two days in a row and then finished 3rd the next day.
I mention the above not just to walk down memory lane and not just to FLEX but to contrast it with the guy at my table who announced that this was the first time he had ever played HORSE. 5 of my 7 table mates didn't got as far as to announce this, but it was obvious that they had pretty much never played any of the stud games and were just flying by the seat of their pants.
In order to win the low half of the pot you need 5 unpaired cards 8 and below (the E in HORSE is Eight or Better referring to this qualifier). I had a shitty low, but with the cards showing I was thre only one who can have a made low. The guy with T56 in theory could be drawing to a better low, but he started with a T up and probably has a pair of Ts or maybe started with 3 suited cards. My chances of getting half the pot here are excellent so when the JJ6 guy bet, I raised from 5,000 to 10,000 and everyone except seat 6 came along.
On 6th street it checked to me and I bet again. Everyone called. At this point we have 69,000 in the pot.
Everyone was dealt their last card (I paired my 4), it checked to me, I checked it and seat 4 squeezed his last card last to act. Finally he bet 5,000, the face up JJ in seat 7 called, the other guy folded and I called. "You've got the low" he said pointing to me. "I have a pair of aces" he continued. A pair of aces? In what world is that going to be the best high hand here?! The guy in seat 7 showed that he has just one pair of jacks with no low. The guy with the aces showed his hand and he had AA2 in the hole meaning he has 8732A for low and I have 87432! Gross! This guy didn't even realize he had a low!
We'll see if I can get through one post without over the top disparaging of my opponents who I'm sure are actually fine people and are just there to have fun...but don't bet on it!
