Multiple Lines

On infinite analysis mode, generally, best possible variation that has so far been searched out, is displayed. With the У+Ф and УЦФ buttons you can increase or decrease the number of lines that are calculated in parallel. Useful to see candidate moves but the quality of any single variation may not be that good. Again more processor speed, available RAM, permitted time can improve the quality. In the example Fritz6a is used.
