K2 by Sergey Meus from Russia has been updated to 0.75. It's an engine in continous development, so we should expect more updates in near future. Thanks to Jim Ablett for bringing it to Android.
Previous compile was based on v0.71. After 30 games played, it collected 1130 ELO in the Rapidroid ranking i expect to release today.
This is disappointingly far below its 2414 ELO level at CCRL 40/40 on a PC. There must have been some incompatibility somewhere which caused that.
We'll see what happens with the new compile soon.
