When i get into this situation and i make a pot sized bet with top pair, and i get raised, it's very difficult for me to decide what to do next. Should i think "well i have a weak kicker and i shouldn't play a big pot, i fold."? Or should i be thinking "I have top pair. There is two other low cards on this board so i probably have the best hand, i call."?
