I ran the moves through Fritz6 on a P-III 500, infinate analysis, letting it decide what was the best move and it took it a while with me forcing moves to announce mate. However it did find a mate this way in 27 moves, so I would think Kasparov + Deep Junior we're right in claiming checkmate within 25 or 26 moves. Terry
