What are felinefehlers? Apparently they are an unexpected hazard in online chess games. Malcolm Pein provides an explanation in today’s Daily Telegraph column.

Malcolm Pein on…Felinefehlers

The battle to reach the last eight of the $200,000 (£145,000) Magnus Carlsen Invitational was decided on the third and final day of the preliminary phase, although there was little change from the overnight standings as many games were drawn.

Magnus Carlsen achieved his stated objective of finishing first in the preliminary section to secure a more favourable pairing in the knockout phase as he eventually overhauled Anish Giri, who had defeated in him in the early rounds. Carlsen defeated qualifier Alan Pichot and drew the rest on day three, including this ‘Double Bongcloud’ against Hikaru Nakamura: 1.e4 e5 2.Ke2 Ke7 3.Ke1 Ke8 4.Ke2 Ke7 5.Ke1 Ke8 6.Ke2 Ke7 draw.

Levon Aronian qualified at the expense of Sergey Karjakin thanks to a superior tie-break. Aronian must have been thankful for this gift from Jorden van Foreest at the end of day two; he had been utterly outplayed. Aronian – Van Foreest after 64…Qd3-f5??

Ian Nepomniachtchi was top scorer with 4/5 on the final day after a mishap on day two. Nepo’s cat jumped onto his chair during his game against Carlsen when he had a “huge edge” after which “he was unable to concentrate”.

The Russian number one finished with a flourish:
