Subject: Still haveing problems

Dear Guys,

I am really frustated because I still can't save the games considered best move
tree. Without doing that I can't continue because I planned to build the move
ordering functions and I need that data.

Can anyone explain me why on TSCP and FAILE they put this on the Alpha Beta
algorim?
while (moves_left)
{
if (make_move)
    {

    score = -AlphaBeta(-beta,-alpha,depth);

    if (score>alpha)
    {
        if (score>=beta)
            return score;

    alpha = score;

    for(j=ply+1;j<pv_length[ply+1];j++)     ///////// This is what I don't
understand!!!!!
       pv[ply][j]=pv[ply+1][j];                    ///////// This is what I
don't understand!!!!!
    pv_length[ply]=pv_length[ply+1];     ///////// This is what I don't
understand!!!!!
    }
}

Reggie told me that this is called the "triangle PV theory", and he told me that
he was going to e-mail me a message but he is very busy now and can't respond
me.

Thanks.
