In the return game, the opening transposes to a Scandinavian Gambit and Critter gets the second-fastest Black win of the tournament so far

Nineteenth pairing: Gull vs Andscacs

In the first game, Gull scored the full point after one of the longest games so far, thanks to an extra pawn in a NPPP vs NPP ending.

In the return game, Gull opted for the 3...c6 which seemed to simply give White too much of an edge.
