This was my first Chapel-Knights-Colony game.
We both opened Chapel-Baker with 4/3 splits. The only buy on the board was Sir Martin and, potentially, Cities. He won the Knight Split and eventually had Natalie, Sylvia, Martin, and Anna while I had only Baker and a few Golds. He was playing multiple Knights per turn, so my only hope was to go for Platina and Colonies, which Knights can't hit, so I did. He greened too late, despite having a decent engine, and I pulled out the win in a crazy game.
There is also contraband as +buy that could work as there are several interesting 5's. I would also save 2 coin tokens and buy silver instead josephine.
I do not think that opponent had decent engine, it looks more like Don Quixote deck (aka village idiot 2.0). On turn 15 his deck is
1 Chapel
1 Dame Anna
1 Dame Molly
1 Dame Sylvia
1 Sir Martin
1 Gold
As only draw is library or city trying to build engine that buys more that single colony looks too slow. Also as chapels reduced decks to 5 cards and knigth will likely trash 6th baker is little better than copper.
I am surprised that it took so long to get platinum, when you trash to 5 card hand you could for example on turn 12 trash sir vander for gold, on turn 13 trash silver gain gold and platinum on turn 14, problem is with timing.
I also would not buy that many knights as opponent could buy sir michael.
