Analysis 

The pilot reported that, during the landing, the tailwheel-equipped airplane touched down and veered left. The pilot attempted to correct with opposite rudder; however, the airplane continued left.

I have discovered that these type of planes need to be slowed down to near stall speed when landing. If you are halfway down a 4000’ runway and loose control, you’re probably going way to fast. Also using the airlerons to control your direction by following the nose is way more effective than the using only the rudder since the rudder effectiveness diminishes due to your tail being on the ground as speed decreases. I only have 600 hours in these short coupled biplanes. Rudder and airleron imputs need to be very small but quick. If you have to think about it, it’s probably too late. They demand practice and your complete attention until you are completely stopped. I try to do at least six landing every time I fly one to stay current. Thanks
