Detect OESD or InsideStraightDraw that Villain might have

[PlayAcesHard]

Is there a way to detect on a straight possible turn or river, that whether the villain can make to the straight in the previous round that holds OESD or inside straight draw? The reason this is important is because then we can reasonably deduct the probability of villain makes to the straight on turn / river (esp. if Bot raises on Flop, villain should call with OESD but not inside straight draw).

For example:

1. Flop: 5d6cKs, Turn: 8d - Villain that holds 67 should have oesd so the turn of 8 or 4 will make villain straight.

2. Flop: 5d8dKs, Turn: 6c - Villain that holds 79 or 47 makes straight, but this is only possible as it was inside straight draw on flop; if bot bets / raises large on flop, villain should fold if only draws on inside straight draw.

I am not understanding the example here. On a 58K board there is certainly a possible OESD (holding 67).

If you want to identify flops where an OESD is not possible you will have to define some board ranks and set a user-variable. There aren't actually that many so it's not a huge task. Keep in mind potential double belly-busters as well.

Hi Egor,

On the 58K board, indeed having 67 will make it oesd. But on the turn when a 6 hits, it doesn't complete the straight for the oesd villain (that holds 67). Only villains that hold 79 or 47 can make the straight, but for villains holding those two combos on the flop, it should be a gutshot draw instead of oesd, and in these situations villains will more likely to fold on a flop bet from the bot. Thus, when the turn is a 6, and villain places a large bet, it will be more likely that the villain is semi-bluffing with a pair + straight draw instead of making the straight complete.

Is there a way to add coding that can reversely find out whether the turn will have straight with gutshot on the flop or with oesd? Hope I make myself clear this time. Cheers

Actually I might just find a way to do it - there aren't that many gssd combos on the flop, it happens on most of the 3gappers (ie. 58 on flop, then 6 or 7 hits on the turn), or all of the 4 gapper combos (ie. 59 on flop, if the turn completes 5 to 9 straight, then it must be gssd on the flop)
