But after ...Nf6 this could be Cambridge Springs, Tarrasch, Orthodox, Tartakover, Lasker, etc. In this case it's the White c5 move that steers us out of the variations. That c5 move seems ill-advised, but it's likely playable because Black's B is begging to be hit.

Amusingly, both castlings are declared inferior, but I hadn't needed one regarding the bad 9...Sh5 (which at least drops the Ph7) and 11...b6 (which loses a piece, but cashing in immediately with f3 and g4 isn't even the best continuation!)
