Sentinel 2.0 uses a neural network to evaluate positions.
The current NNUE architecture is (768->128)x2->1 trained on self-play data.
I currently don't have the resources to train larger networks, but in the future I would like to train at least (768->512)x2->1.Sentinel uses many search heuristics that were inspired by top chess engines or found on a chess programming wiki.

Many thanks to all Chads on the Chess Engine Programming Discord who helped me and taught me the basics of engine programming.
