Given the following context:  At this point Lissitzky subscribed fully to suprematism and, under the guidance of Malevich, helped further develop the movement. In 1919–1920 Lissitzky was a head of Architectural department at the People's Art School where with his students, primarily Lazar Khidekel, he was working on transition from plane to volumetric suprematism. Lissitzky designed On the New System of Art by Malevich, who responded in December 1919: "Lazar Markovich, I salute you on the publication of this little book". Perhaps the most famous work by Lissitzky from the same period was the 1919 propaganda poster "Beat the Whites with the Red Wedge". Russia was going through a civil war at the time, which was mainly fought between the "Reds" (communists, socialists and revolutionaries) and the "Whites" (monarchists, conservatives, liberals and other socialists who opposed the Bolshevik Revolution). The image of the red wedge shattering the white form, simple as it was, communicated a powerful message that left no doubt in the viewer's mind of its intention. The piece is often seen as alluding to the similar shapes used on military maps and, along with its political symbolism, was one of Lissitzky's first major steps away from Malevich's non-objective suprematism into a style his own. He stated: "The artist constructs a new symbol with his brush. This symbol is not a recognizable form of anything that is already finished, already made, or already existent in the world – it is a symbol of a new world, which is being built upon and which exists by the way of the people."In January 17, 1920, Malevich and Lissitzky co-founded the short-lived Molposnovis (Young followers of a new art), a proto-suprematist association of students, professors, and other artists. After a brief and stormy dispute between "old" and "young" generations, and two rounds of renaming, the group reemerged as UNOVIS (Exponents of the new art) in February. Under the leadership of Malevich the group worked on a "suprematist ballet", choreographed by Nina Kogan and on the...  answer the following question:  Who worked on transition from plane to volumetric suprematism?

Given the following context:  Byzantines were avid players of tavli (Byzantine Greek: τάβλη), a game known in English as backgammon, which is still popular in former Byzantine realms, and still known by the name tavli in Greece. Byzantine nobles were devoted to horsemanship, particularly tzykanion, now known as polo. The game came from Sassanid Persia in the early period and a Tzykanisterion (stadium for playing the game) was built by Theodosius II (r. 408–450) inside the Great Palace of Constantinople. Emperor Basil I (r. 867–886) excelled at it; Emperor Alexander (r. 912–913) died from exhaustion while playing, Emperor Alexios I Komnenos (r. 1081–1118) was injured while playing with Tatikios, and John I of Trebizond (r. 1235–1238) died from a fatal injury during a game. Aside from Constantinople and Trebizond, other Byzantine cities also featured tzykanisteria, most notably Sparta, Ephesus, and Athens, an indication of a thriving urban aristocracy. The game was introduced to the West by crusaders, who developed a taste for it particularly during the pro-Western reign of emperor Manuel I Komnenos.  answer the following question:  What is the name of the game that John I died while playing?
Ans: Tatikios

Given the following context:  A former police detective and Vietnam veteran in New Orleans and a recovering alcoholic, Dave Robicheaux, is living a quiet life in the swamplands of Louisiana with his wife Annie. The couple's tranquility is shattered one day when a drug smuggler's plane crashes in a lake, right before their eyes. Robicheaux succeeds in rescuing a lone survivor, a Salvadoran girl, whom he and Annie quickly adopt and name Alafair. With the arrival of a DEA officer named Dautrieve and an inherent connection to Bubba Rocque, the leading drug kingpin in the area and Robicheaux's childhood friend from New Iberia, Dave becomes involved in solving the case and consequently finds himself and his family in danger. Robicheaux is assaulted by two thugs as a warning. With help from his former girl-friend Robin, an exotic dancer who still has feelings for him, he continues to investigate. His longtime acquaintance Bubba denies any involvement, but Dave warns him and Bubba's sultry wife Claudette that he is going to find out who is behind all this and do something about it. He tracks down one of the men who attacked him, Eddie Keats, and splits his head open with a pool cue in Keat's own bar. Killers come to the Robicheaux home late one night. Robicheaux is unable to prevent his wife Annie from being killed. He falls off the wagon and neglects the young girl they adopted. Robin comes to stay with them. Clearing his head, Robicheaux seeks vengeance against the three killers. He first goes after a large man called Toot, chasing him onto a streetcar and causing his death.

Going after the last and most dangerous of the killers, Victor Romero, he knows that someone else must be giving them orders.  answer the following question:  What is the full name of the person who chases someone onto a streetcar and causes his death?
