I ran across an interesting situation yesterday in my family PLO game. I held
on the button and opened. The flop came
, giving me an inside draw to a straight flush. Then turned the
, giving me 12 outs to straights - any 4, 8, or queen. I'd never heard of a triple gutshot before so I spent some time thinking about it and came to a few realizations.
This draw isn't possible in Hold'em since it requires a total or 8 cards on the board and in hand. Because of this, triple gutshots only occur on the turn in Omaha games. Double gutshots only require 5 (for example: 56 on a 248 board), but can also come in a slightly different arrangement with 6 cards. For the 5 card arrangement, there is a 3 card straight in the middle, but for the other form, only two connecting cards are in the middle of the straight.
Double Gutshot 1 (hand+board): A 3 4 5 7
Double Gutshot 2: A 2 4 5 7 8
As you can see, double gutshots are only possible if the highest and lowest card in the draw are at least 6 ranks apart. As such, only 8 arrangements of the simpler double gutshot draw are available, starting from a draw to 7-high and 5-high straights and concluding with the Q-high and A-high combo.
Triple gutshots follow the form of the 5 card double gutshot but add 3 cards before or after the draw to create additional outs.
Triple Gutshot 1 (hand+board): A 3 4 5 7 8 10 J
Triple Gutshot 2: A 2 3 5 7 8 9 J
We see here that the highest and lowest card must have a gap of 10 ranks. This leaves only 4 available combos of this draw; remember in straight draws there are effectively 14 ranks because aces count as both high and low. Of course, this draw only works if players hold a specific combination of the cards necessary for the draw. If the player held A 3 8 J in example 1 on a board of 2 5 7 9, the 6s would no longer be outs.
Anyway, pretty rare! I'm sorry this post got a bit mathy, but I didn't know what else to do but explain it since it's so unlikely to end up in this situation that it's not really even a useful draw. I'm sure some of you are aware of this one but it sure surprised me.
