Teglas,M(2141)         -Nadasi,B(2161)                  draw

Kaazdu,K(1778)       -Balla,A(1764)                      0-1

My team RAC got destroyed. We could only field 5 players so we were off to a bad start. I had a promising position as black in Sicilian Kan but lost my way in a sharp position. Our Captain, Balla saved some face for us by winning a game.

The car journey was the most interest part of the round as were drove off from the Ors Ver Ter subway into what looked like suburban nowhere. We explored around with map in hand until we found the small office of a politcal party(used to be more popular in days gone by) and settled down do play.
The captain did his job and gave everyone a chocolate bar but this time TWIX power could not help me.

Here is a tough game played on board one.

Nádasi,Balázs (2161) - Téglás,Márton (2141) 
Sicilian Najdorf 6.Bg5[B96]
BTCH Division 4 Budapest (1.1), 08.10.2012 [Yip]
This unrated game will otherwise go unpublished and unnoticed but shows the value of practice games. Both players follow theory until black extends theory on move 19. The novelty does not improve black's chances as white does not fully exploit the chances given. However, the game is full of drama and excitement. Unfortunately RAC lost the match to Hort SE 4.5–1.5.[Yip]

Now the game leaves GM practice. Black offers an ending to reduce white's pressure[Yip]
