Check extension fix (2200!)
(+20 ELO)
- Extends checks before qSearch (predicting less elo gain if I had a king safety evaluation).
- Fixed Null Move Pruning constraints to play better in the endgame
- More comments (to help me and others to understand the magnitude of improvements certain code added)
This should bring us over the 2200 hump! Therefore, I am making the version number v1.2 (instead of v1.1.x, as would be normal with this size of change)
