That being said, if the analysis that you're interested in is down to such a small level where backdoor straight draws sway a decision, then you may want to consider using GTO analysis instead. Manually setting up ranges down to a level of such a small fraction of equity would require a considerable amount of effort. With GTO analysis, all tiny details are taken care of for you automatically.
Hi Scylla,
Backdoor straights have much more influence on the GTO solution than what you seem to suggest. On the flop, they can play as tie breaker between playing a hand and folding it, as much as backdoor flush draws. And in real life, they even have better implied odds because a straight from a backdoor is more likely to be called than a flush from a backdoor flush.
As Janda mentionned in his book ANLH, backdoor draws have hand signaling property, you know on the turn if they are good or not, which make them easier to play than small/medium pairs.
A backdoor straight where you have 2 hole cards(57s) making a 3 straight with the board(Q62r) has similar equity than a any given backdoor flush. You have 48 (16x3) turn/river combos that can make the straight and a backdoor flush has usually 45 (10x9/2) turn/river combos, for a bit more than 4% equity each. But what is great about this equity is that there 16 cards on the turn that will turn your backdoor straight into a straight draw and 8 of them is for an OESD!
For GTO solutions, where you split your combos between Value/Bluffs/Air, backdoor straights or/and flush often make great Bluffs to tag along Value hands, which is why they would be useful in GTO+. But they are not made equals, so I would suggest to split them in 3 groups: (1) BD straight with three consecitive cards (2) BD straight with one Gap (3) Other BD straight.
A+
