Born.................I think you are confusing blitz with CTTH. We had Pebble Beach, same two challenges for something less than 2 months, back I think in 2010. At the time we all hoped we would get it as stroke play. According to WGT some liscensing issues caused us not to get it. I think we got Oakmont that year instead (US Women's Open site). Shortly after than the PB tracts vanished not to be seen again.
It's good to have them back even in this format, hope they stay and we get the full course before the Open goes back there, I think in 2019.
