Hero is a bumhunter who waits on tables for fish to join. 100 stack joins, which Hero presumes to be a better player. Hero opens 99 3x, first hand in and Villain makes a small 3b to $7. Should I 4b for value here, or call the small 3b and play post flop? If we get 5b over our 4b can we commit? I feel that when Villian 5b over a small 3b, we see big pairs very frequently that crush 99. Thoughts?
