Gold has just captured a silver dog in f6, and several more captures could quickly follow.
A race position occurs when both sides can make quick progress in different parts of the board. A race will slow or stop when one side chooses defense over offense. If too many captures occur, however, there will be few pieces left to use for defense. It is thus important to avoid or quickly exit a race that one cannot ultimately win.
In the position at right, each side left a home trap vulnerable. Silver has a strong attack on c3, but has already lost a dog in f6 and will lose his camel if he doesn't use two steps to save it. If Silver goes for an all-out race, he will now make two captures in c3; in between those captures, Gold will presumably capture the silver camel in f6. Gold must then decide whether to keep his elephant in the northeast, or move it to the southwest to stop the cleanup in c3. In the actual game, either side could have benefited by slowing or stopping the race at different times.
This race centers around goal threats and trap control. (Game)
In the position at left, each side is threatening goal, but Gold's threat is currently stronger. Silver is to move, and must stop the d6 rabbit; merely freezing it in place would not be enough, as Gold could unfreeze and unblock it with Dc7s rd7w, leaving two steps for goal. If Silver used her elephant to stop this goal, her own threats in the east would be gone. One strong option for Silver is mg6ww Rd6s me6w; this would preserve Silver's eastern threats, delay Gold's threats, and even threaten the c7 dog. Gold might then be tempted to capture the g3 rabbit or flip the b6 horse, but could not afford to take the race in that direction, as he is behind in material and will further lose his camel, which he has no good way to save. Gold must focus on the northwest; he could reassert full control of c6 with Eb5en md6e Ec6e. There may be several more captures, but goal threats are key for Gold, as raw material favors Silver.
In most cases, the first one to lose home trap control could not win a race. It is important to defend one's home traps at least until one has a strong attack on an away trap.
