the thing about within manhattan distance (small) of other stones type heuristics is that they seem to leave out the possibility of tenuki. s. On Thu, Dec 11, 2008 at 5:27 AM, Thomas Lavergne [EMAIL PROTECTED] wrote: I've not tryed it for the moment due to lack of time for computer go, but

Hi guys, It would be interesting to know how everyone limits the number of possible moves at the beginning of the game. Assuming the board is 19x19 with no handicap and black placed a stone, that leaves (in theory) 390 possible positions which translates to 390 children from the root

Back to the original question - accounting for symmetry, there 55 distinct opening moves on a 19x19 board. Are there a noted collection of these opening moves? if so could you direct me to the material? cheers ___ computer-go mailing list

People sometimes play all kinds of silly things. It's not necessary to anticipate it all, just make sure you can keep playing reasonable moves when the other side plays strangely. There's little problem with continuing to play in the corners and sides when your opponent decides to do something
