Do less LMR extensions This patch restricts LMR extensions (of non-transposition table moves) from being used when the transposition table move was extended by two plies via singular extension. This may serve to limit search explosions in certain positions. This makes a lot of sense because the precondition for the tt-move to have been singular extended by two plies is that the result of the alternate search (with excluded the tt-move) has been a hard fail low: it is natural to later search less for non tt-moves in this situation. The current state of depth/extensions/reductions management is getting quite tricky in our search algo, see https://github.com/official-stockfish/Stockfish/pull/3546#issuecomment-860174549 for some discussion.
