I know pot odds aren't quite as important in No-limit as they are in limit (where they seem to be paramount - I'm playing mostly STTs and MTTs these days) but was wondering if I'm doing this math right....

1. Odds to hit gutshot straight after flop (4 "outs" - assuming you get 1 more card) - ~11.75-1 (so you need at least 10.75-1 pot odds to call)

2. Odds to hit open-ended straight after flop (8 "outs" - assuming you get 1 more card) - 5.87-1 (so you need at least 4.87-1 pot odds to call)

3. Odds to hit a flush with 4-flush on the flop (9 outs - 5.2-1 so need 4-1 pot odds)

4. Odds to hit a set on the flop with any 2 pair (2 outs - 23.5-1 - basically need it to check all around)

My math ok here? With combination math how would these read assuming you go all-in after flop and get to see full board (or are calling a bet and using implied odds to justify).

Thanks!!

These look like they're right, but you're confusing the meaning of odds.

Your odds of hitting the gutshot are 10.75 to 1, not 11.75 to 1. You'll hit it one time in 11.75 tries. That's an important distinction.

Ya as someone just pointed out

4:1 means 1 out of 5 or 20%

thus

7:3 would mean 3 out of 10 or 30%
