Abdusattorov leads the Tata Steel Masters 4.5/6 after a horrendous blunder by Gukesh - 6

Nodirbek Abdusattorov took the lead of the Tata Steel Masters alone after defeating Gukesh following a terrible one move blunder from the Indian, meanwhile joint leader Hans Moke Niemann lost against Vincent Keymer. In the only other decisive game Yagiz Kaan Erdogmus beat Jorden Van Foreest in a game settled near first time control, both players missed big ideas in spite of not being in serious time trouble.

The other games were drawn. Matthias Bluebaum was pretty upset with himself that he didn't convert winning chances against Arjun Erigaisi. Aravindh Chithambaram was dead lost against Javokhir Sindarov who blew the win with his final move before time control with only a few seconds left. Anish Giri had a small edge against Thai Dai Van Nguyen. Vladimir Fedoseev against Praggnanandhaa was a fairly dull draw.

In the Challengers Andy Woodward leads on 5/6 after losing his first round game he's now won 5 in a row including today's long grind in a pretty equal Queen and Pawn endgame against Carissa Yip which ended with a win in 131 moves, problems only started on move 128 for Yip. Joint leader Faustino Oro had a less good day losing his first game to Max Warmerdam.
