This gives an indication of how many legal chess moves there are at each ply, 2ply = 1,600 3ply = 64,000 4ply = 2,560,000 5ply = 102,400,000 6ply = 4,096,000,000 7ply = 163,840,000,000 8ply = 6,553,600,000,000 9ply = 262,144,000,000,000 10ply = 10,485,760,000,000,000 11ply = 419,430,400,000,000,000 12ply = 16,777,216,000,000,000,000 13ply = 671,088,640,000,000,000,000 14ply = 26,843,545,600,000,000,000,000 15ply = 1,073,741,824,000,000,000,000,000 16ply = 42,949,672,960,000,000,000,000,000 17ply = 1,717,986,918,400,000,000,000,000,000 18ply = 68,719,476,736,000,000,000,000,000,000 19ply = 2,748,779,069,440,000,000,000,000,000,000 20ply = 109,951,162,777,600,000,000,000,000,000,000 DEEP JUNIOR 8 YY 20ply = 715,580,000 99.999999999999999999999349183781 % filtered moves SHREDDER 7.04 (strongest settings) 15ply = 38,826,000 99.999999999999996384046971797943 % filtered moves As you can see, your home pc computer isn't even looking close to 1% of the moves, Deep Blue 1997 calculated 200,000,000 positions a second, so if it wanted to look at a TRUE 7PLY, it would take 13 minutes and 30 seconds. I agree with Mike 100%, we'll never solve chess,
