The Pole has a 0.5 point lead after five rounds of play at the Wyndham Garden Dresden hotel - the venue for the previous two editions of the Championships in 2013 and 2015.

In his first match he claimed a 1-0 win over Zoltan Raibl of Hungary before doubling his tally with a victory by the same scoreline against compatriot Tadeusz Zoltek.

Tazbir then continued his emphatic start by overcoming another fellow countryman in Jacek Stachanczyk 1-0 while he added a fourth win from four matches against Viktor Varezhkin of Russia.

The only slight blemish on Tazbir's card so far is 1/2 - 1/2 draw against Germany's Oliver Müller, which leaves him on 4.5 points for the tournament.

In second place in the overall standings is 2013 champion Stanislav Babarykin.

The Russian beat Germany's Raphael Zimmer, the newly-crowned junior world champion for the disabled, 1-0 in his first match in the German city. 

He built on that win with a further two 1-0 victories over Marcin Chojnowski of Poland and compatriot Denis Palin.

Babarykin sits on 4 points overall, though, after suffering two draws in his last two matches.

He first finished level at 1/2 - 1/2 against Mirko Eichstaedt of Germany before matching that result against Artur Kevorkov, another German.

A total of 70 players from 11 National Federations on three continents are competing at the event, which is due to conclude on Friday (October 13).
