Clocks were available, but not required. I didn't use them in this tournament (never met Louis!), because noone pretended to use them against me and I also was neutral.
The only real longest game (several hours) I played against E. Bruch, where I missed a win in the ending and then tried for another couple hours, hoping for some miracles. Unfortunaly chances doesn't come together very often

especially against players of Mr. Bruch calibre !
