    4. Laser engine, can actually play in C4a, it need more time to think, for example, 5 sec per move, but still it doesn't show any info-depth, kns, e.t.c.

  4. V0.2 needed polyglot according to Jim Ablett. The same may be repeating. If so, a specific build of polyglot must be compiled with reference to the config file. That means like for example Laser.ini inside Polyglot binary. So, polyglot looks for ini file and the ini file looks for the engine. CfA uses the polyglot binary as an xboard engine.

  5. I've tested the polyglot trick by replacing just the engine file in my current Laser 0.2.JA config. It works with CfA. The theory is valid. I will upgrade Laser in Rapidroid using this workaround.
