Another type is the tsugi no itte 'best next move' problem, which is non-checkmate problem of which the goal is to find the next best move/s that will give you an advantage, which may be encompass the endgame close to checkmate but may also include opening and middlegame strategies.)

The faster the program produces cutoffs, the faster the search runs. The null-move heuristic is designed to guess cutoffs with less effort than would otherwise be required, whilst retaining a reasonable level of accuracy. The null-move heuristic is based on the fact that most reasonable chess moves improve the position for the side that played ...

Darkforest uses a neural network to sort through the 10 100 board positions, and find the most powerful next move. [9] However, neural networks alone cannot match the level of good amateur players or the best search-based Go engines, and so Darkfores2 combines the neural network approach with a search-based machine.
In about 2004, he had an opportunity to tell Alan Kotok that searching the 7 best moves at each of the first two plies, and limiting the search depth to two would have done better than the default widths of "4 3 2 2 1 1 1 1", attempting eight plies in Kotok-McCarthy's REPLYS subroutine which generated each player's next plausible moves.
