Odds question

[RedeemerKing]

This situation presented itself to me when I was playing 2-4 on Partypoker. What are the odds when you have 3 to a straight in succession and 3 to a flush after the flop. What are the odds of making either the straight or the flush. Forget about overcards and runner runner two pair or 3 of a kind as possible ways to win. Sometimes on Party you will be getting over 20-1 on your money after the flop and that seems like enough to call but would like to know exact odds.

Treat these backdoor draws as approximately 1.5 outs each. That means that on a loose table, you should be calling these double backdoor draws on the flop for one bet very frequently.

23:1 on the backdoor flush draw
21.5:1 on the backdoor 3-straight
11:1 combined
2 cards give you 15 outs
2 cards give you 12 outs
6 cards give you 9 outs
6 cards give you 8 outs
6 cards give you 4 outs


To get there, you will have to probably call another bet on the turn. Which makes the play less profitable than if it were a true 1 outer where you can make your hand on the turn.

Also, some of the times you hit the 11:1, you have to nail a 4 outer on the river. For example, you have A7, the board is 68Q. You have a three straight, and sometimes you make a straight when it comes T then 9 for a gutshot, or 4 then 5 for a gutshot. You may not have the odds to call a gutshot once the bet doubles, however.

The plus side is that people are less likely to believe you made a runner runner hand, so you usually get paid off on the end.

Bottom line, it's probably not a good play on a rainbow board without an overcard or a pair to go along with it unless you are getting 15:1.

And if you're against a 2 flush, that takes away 4 of your straight card outs, so you need even better pot odds.
