fyp = fixed your post

your example is perfect. Now, how much extra money would you have to get out of him if you hit for the call to start showing a profit (this is the implied odds thing that people have a tendency to overestimate). Give it a go, if you get it wrong someone will correct it.

Also, note how this changes if his bet of $1 had put him all in. In white below (highlight it to read), but figure it out for yourself first.

it would mean your pot odds would be 1/4 (still) but you would have two chances of hitting your straight (turn and river) so your odds of hitting would be about 8x2x2 = 32%. As 32 > 25, it's then a call
