My games are really just an add on to hundreds of other games that were played with CM6555 and CM6000 some time back on this forum. These games were proof that CM6555 and CM6000 ( Selective Search set to 10 and all other settings at Default-Normal Setting )were better than CM6000(default settings) at different time controls! Thankyou for your input, Terry
