Chessandgo decided to switch his elephant out of the fight for c3 and into a furious goal attack in the east. On move 31 Fritzlein launched a desperate central counter-attack to generate a goal threat of his own. This netted Fritzlein only a horse in c3 while both of his dogs fell to chessandgo in f3, leaving chessandgo with a material advantage of two dogs for a cat and a rabbit. As soon as chessandgo secured this large advantage, however, he blundered a dog on move 34, leaving Fritzlein with a slightly better material as well as better goal prospects.
On move 36 Fritzlein made a premature western rabbit advance, which merely gave chessandgo an opportunity to regroup defensively.

However, in exchange for his western rabbit, Fritzlein got a dangerous threat started in the east with cat and rabbit advancing against only rabbits. Each player also generated central goal threats. On move 44 Fritzlein won a defensive rabbit in f6 while chessandgo captured Fritzlein's central rabbit. This allowed Fritzlein to create an unstoppable two-move threat in the east on move 45. Chessandgo's last gasp was to re-establish his powerful central goal threat, but Fritzlein had one step to delay chessandgo's central threat from four steps to five, while Fritzlein's other three steps insured him an eastern goal on the following turn.

Combining the results of the preliminary and the final, Fritzlein's 11-0 performance was a convincing tour de force, including eight wins against the second through fifth place finishers. Chessandgo, apart from his three losses to Fritzlein, was 8-0 against the rest of the field for a clear second. Adanac was 8-0 against everyone but Fritzlein and chessandgo, losing once to the former and twice to the latter, so Adanac's claim to third place is clear. However, arimaa_master's came within an ace of knocking off Adanac for third place in the tournament's final game, and would probably have been third place finisher apart from an untimely disconnection; certainly arimaa_master was deserving of fourth place.
the opening setup saw sporadic uptake among other players as well.

Fritzlein vs. chessandgo
Both players used the opening moves to activate their elephants, horses, and camels in that order. Chessandgo's sixth move was the first commitment by either player; he advanced pieces to wall Fritzlein's g5-elephant out of the center. Fritzlein responded by advancing his eastern horse to h6, threatening to flip chessandgo's camel offsides. Chessandgo switched gears and retreated his camel to pursue the intruding horse, but couldn't backpedal his entire wall quite fast enough; his dog got pushed offsides by Fritzlein's elephant. In a effort to get sufficient counterplay for his dog, chessandgo blundered on move 7, hanging his f7-cat, which Fritzlein pounced on with his elephant.
In the next few moves Fritzlein recentralized his elephant while his horse was secured as a hostage by chessandgo's camel. On move 11 Fritzlein tried to rescue his hostage horse, but left his elephant on g6 where chessandgo's elephant promptly blockaded it.

While chessandgo captured the rabbit, arimaa_master finally got chessandgo's western horse held hostage by a camel, but at the same time gave up his eastern horse hostage to chessandgo's camel. Each side freed his hostage horse, but chessandgo emerged with the bonus of taking arimaa_master's camel hostage.
On move 54, arimaa_master used his elephant to prevent chessandgo from maneuvering his camel hostage into a good position, but overlooked thereby that chessandgo's a-rabbit had a clear path to goal on the next move.

Adanac could have given up his dog and hunkered down to a long defense with a material disadvantage, but instead he played to defend c3 with little pieces while protecting c6 with his elephant and eventually generating a counter-attack on c6. This plan proved catastrophic, for by the time Adanac freed his camel for attack and won a rabbit in c6, Fritzlein had captured two rabbits, a cat, and a horse in c3. Having wiped out Adanac's western corner, Fritzlein marched a rabbit to goal there on move 24.
chessandgo vs. arimaa_master
Chessandgo opened with a western elephant-horse attack, which arimaa_master was content to defend rather than counter-attacking. Chessandgo played for a rabbit pull, not a swarm, and his progress was slow, especially given that arimaa_master several times reversed one of chessandgo's moves, only to have chessandgo redo it and force a deviation.

The silver elephant was threatening a gold dog, so Bomb advanced a rabbit to d6 to defend the camel. When Opfor intensified the pressure around the trap, Bomb decided to return its elephant to c5 to secure the zone. Opfor immediately switched quadrants, commencing an Elephant + Dog attack in the northeast. When Opfor advanced a rabbit up the h-file on move 32, it broke the resistance of the silver side. Opfor won 2 rabbits for a cat, and after Bomb shifted more defenders to the east the gold dog trapped another rabbit in the northwest, opening a path for another gold rabbit. Bomb did not have the means to deal with two rabbit threats simultaneously, and Opfor won on move 37. Bomb will try to avenge its first loss when these two bots meet again tomorrow for a round 6 re-match.

Adanac knocked out the supporting rabbit from b3, capturing 99of9's elephant, and brought a rabbit to goal on the following move. This was the second elephant capture of the World Championships, quite bizarre considering their rarity. 99of9 is eliminated by his loss, while Adanac advances with one life left.
