Thanks I understand now why you can only use those odds if going all in (combined odds) that's great.

Set to full house. You have three cards the same so you have two left, either of which needs to be paired. There are 4 cards of the same type in each deck, so you have 6 outs, plus the one other card to make your quad - so 7 outs, on the turn. I think I've got that right thanks, why do you get an extra three outs on the river?
