Some people like to just call the raise and others like to reraise to the point of going all in assuring that they will get to see all the cards. I think both plays have there place but how do you decide which is the correct play for any given situation. Personally the percentage of my stack it will cost me to call is important to me. I mean if i have 5 bucks on the table and it's gona cost me 3 to call i think it is wrong to cold call and hope to hit a ace or king on the flop.
