Quick pot odds calculations

[Ronaldadio]

Hi Guys, hope u r all winning lots!!!

I know we have pot odds calculators but if you are sitting at a live table you can`t turn on your pc!!!

Is there a quick way of calculating your pot odds in your head.

Also, I might have worked out how, but this may already be well know and nothing new, and as I`m quite new to poker I`m not sure if knowing your pot odds before the flop is relavant. But here is the way I think you can work it out:-

Example 1 - U have 10s,Jh and the flop is 8d,9c,3s leaving u with an open ended straight. Forgetting about pairs, u have 8 outs to catch straight. I would work this out by saying 8x2+2=18% chance(if only river to come) but if we have river and turn left multiply by 2 again and minus 2. Therefore with two cards to come 8x2+2x2-2=34% chance. (about 2 to 1)

Example 2 - U have poket 10`s pre flop. The chances of catching another 10 = 2 outs. Therefore 2x2+2=6% chance (if only river to come) I would then work out chances this way 2x2+2x3-2=16%. (about 61/2 to 1)

I would be interested to know if the calculation works and what you guys think.

I`m new to poker, so if I`m "barking up the wrong tree" don`t hesitate to let me know.

Happy hunting guys!!!

yes thats relatively close......post flop with 2 cards to come is number of outs times 4....post turn is number of outs times 2.....its roughly the same

... and the reason it works is that there are about 50 cards in a deck, so each card has about a 2% chance to show up (1/50 = 2%).
