Got a few qustions about this post prob easy but im a newbie
Happy WroteIn Hold'em, whit 2 cards to come, the formula should look like this:

(8/47)+(8/46)*(1-8/47)
= 0.1702 + 0.1739 * 0.8298
= 0.1702 + 0.1443
= 0.3145

So you got 31.45% chance, or 2.17 to 1, of making the straight whit TWO CARDS TO COME.

Round the odds of making it to 2:1

So whit 12$ in the pot and a 4$ bet you need to call 4$ to win 16$. You are getting 16:4 or 4:1 on the call whit 2:1 of making your hand. Of course the opponent may bet again on the turn and ruin your odds. That's why it is advice to only play draws in position in NL, A chk out of position on the turn screems a draw an many opponent will charge you again in this spot, destroying your odds.

When in position, say you got your straight draw whit two overcard like Q J on a 2 9 T , you might want to raise and take a free card on the turn. Any Q or J may win you the pot. Also note the backdoor flush potential witch can be very valuable because your opponent will not fear two running hearts hitting.

I understand how he came up with (8/46)+(8/47) for the 2 cards and outs and cards he hasnt seen remaining but how did he and what is the (1-8/47) and how do you add divide or what ever you did to that to come up with 0.8298 Ok at the end he ends with 0.3145 that = 31.45 get that but at then he changes it to 2.17-1 dont see how he got that either then he got the pot odds 16$ in pot 4$ to call 4-1 get that so your odds vs pot odds are 2.17-1 to 4-1 get that also wondering how much better do your odds need to be verses you pot odds to justify a call i dont even know if 4-1 2-1 is better if someone could explain that too would be awsome thats all for now ; p
