Oh no, not another parham thread...
dumb beginnings

I was never a fan of the grob/spike (1.g4), but have seen it in blitz once or twice. I guess it's technically not the dumbest though, you'd have to figure 1. a3 or 1.h3 would be. However, some people play those moves to play their black repertoirs as white...
What is the dumbest opening for white that you've actually seen played?
