the best bluffer is not afraid to go over the top on a big bet. That shows class!!!! sometimes people think when they bet alot people will fold !!! When you see someone make a big bet , it either means they are bluffing , or semi bluffing normally. Normally if they think they got you for sure, they will make small bets to keep you in the pot unless you have been calling their small bet for a while, then they will try to raise the bet a little bit. DONT BE AFRAID TO CALL THE BIG BET!!!!!!!!!!
