This is why you will sometimes get a crazy puzzle from the early 1900s where even Stockfish can't find the elaborate set of forcing moves that lead to a winning position. So, the biggest flaw of Deep Blue was its sub-optimal positional evaluation methodology, which wasted processing power on every position until a certain depth, unlike modern engines which make use of advanced heuristics to determine logical approaches.
#Deep blue chess online software#
Deep Blue didn't have the highly sophisticated heuristics that we have today, which meant it relied on a specialised supercomputer to make brute-force calculations of 200 million positions per second.ĭeep Blue was far faster than any current chess program on even the fastest desktop computers (Deep Blue searched about 200 million positions per second, while Stockfish, a typical example of modern chess engines, searches about 20 million positions per second on a state-of-the-art 16-core PC), but the software was much more primitive. Unfortunately, it doesn't work like that. Please continue to give us your feedback and suggestions on how we can help make /r/chess better for everyone.
