Stage 1b started with a bang, as the clear favorite Stockfish was held to a draw by the newcomer to this season Vajolet2 (by Marco Belli). In a Nimzo-Indian with 4.e3 O-O , Vajolet created a symmetrical pawn structure and kept cool through the middlegame, not committing a single inaccuracy.

This draw ended the hopes of Stockfish fans that the engine could pitch a 15-0 shutout this stage, leaving last year’s Fisher like success of 11,0/11 to be the valid record.
Critter 1.6a took an early lead in the standings. The 3078 ELO engine had black against the 800 ELO lower rated Firefly. In a Reti: KIA game, Critter steadily built advantage and converted it to a full point. Replay the game here
