Mystery Solved

DREW with a 1937 this afternoon in round eight of the South Wales International after futilely trying for almost 60 moves to win a knight-v-bishop ending.
Perhaps more interesting was that after the game, grandmaster Nigel Davies cleared up something that had been puzzling me from the postmortem of our round-one game (https://beauchess.blogspot.com/2019/07/grandmaster-crush.html).

White to make his 13th move in Davies (GM2484) - Spanton (1900)

ND played 13.c4!?, commenting in the postmortem that after 13...dxc4 White was left with a little centre.
I tried to rationalise this in my blog by speculating that what he meant was White ends up with the only central pawn.
However, as he explained this evening, what he had intended to say was that his move dissolved my little centre (pawn on d5 versus pawn on e3), which makes much more sense.
It only goes to show that if you are not sure what a (much) stronger player is trying to say, ask!
