Tal's the man!  I forget how he put it exactly, but something to the effect of "
There are correct sacrifices, and then there are my sacrifices".

I never could make his insane style of sacrifices work because I can't really
see what was behind them.  He seemed to complicate things an awful lot, I think
that was so he always had something to fall back on.
