Fix TB score output in UCI without using TB This is a rewrite of the fix introduced for https://github.com/official-stockfish/Stockfish/issues/4413 in https://github.com/official-stockfish/Stockfish/pull/4591 by @windfishballad it targets only the relevant part of this issue that returns TB scores (CP 20000) without using TB due to the downgrading of potentially false mates from the TT to an optimal TB score. the difference is that it is a much clearer code that introduces a separate TB_VALUE constant to account for a correct distance from the TB_VALUE with MAX_PLY. the originally posted position in the issue does not trigger the problem anymore, so here is a new position to test: ``` position fen 3k4/8/8/8/8/8/3BN3/3K4 w - - 0 1 go infinite ``` Passed non-regression STC: https://tests.stockfishchess.org/tests/view/65578994136acbc57353b258 LLR: 2.96 (-2.94,2.94) <-1.75,0.25> Total: 119264 W: 29993 L: 29863 D: 59408 Ptnml(0-2): 372, 13692, 31379, 13812, 377 Passed non-regression LTC: https://tests.stockfishchess.org/tests/view/6558323f136acbc57353c1ca LLR: 2.94 (-2.94,2.94) <-1.75,0.25> Total: 237834 W: 58791 L: 58792 D: 120251 Ptnml(0-2): 193, 26200, 66111, 26241, 172 fixes https://github.com/official-stockfish/Stockfish/issues/4413 closes https://github.com/official-stockfish/Stockfish/pull/4591 closes https://github.com/official-stockfish/Stockfish/pull/4882 Bench: 1305821
