The Polish Grandmaster Radoslaw Wojtaszek is known for his strong white color. After his loss in round three against Anish Giri in Qatar he wanted to recover as quick as possible with the white pieces. Things did not go so well for him at the beginning of his game against the yesterday's hero D. Vocaturo:
