Vincent is at least partially right, and probably 100% right. TBs are useful
*before* the position arose OTB. If the program probes during the search than
it, for example, can find a winning exchange when there are still 10-12 pieces
left, or it can avoid exchanging to the position that is drawn despite programs'
advantage.

So it is possible that can win that event *if his program used TBs, and opponent
did not*. I cannot say what would happen if all the programs used TBs, as I am
not a chessplayer myself and cannot evaluate the positions 5-10 moves before the
final ones. I have to ask good chessplayer and trust his opinion, and Vincent
definitely is much better chessplayer than me :-)
