EDIT

butHowever, if I use infinite mode, houdini calculatingHoudini calculates and returnreturns a value approxapproximate ’+1. `+1.30` till `+1.42` (at30’, until ‘+1.42’ at the moment I editedited this) which. This means it is definitely a win for White. [based[Based on houdinithe Houdini guide, `+0.8`‘+0.89’ means an 80% chance of a win, `+0.9`‘+0.9’ for a 90% chance, and so on..].
