Jan-25-09  rwbean: "At the end of the [second round] game, Deep Thought calculated that it could checkmate its opponent in 19 moves, that is, 19 moves by Deep Thought plus 18 replies by the opponent, for a total of 37 plies." -- "Behind Deep Blue", p83.

It's mate in 14 according to Glaurung 2.2. I'm impressed by DT and Glaurung's performance -- there are lots of "quiet moves" in the PV, so Rybka 3, Crafty 22.9 and Toga II 1.3.4 don't find the mate quickly from the start position.

30. Rf1 Qg5+ 31. Kb1 Qf6 32. Rxf6 gxf6 33. d8=Q Rxe8 34. Qxe8+ Kg7 35. Qe7+ Kg6 36. Qe4+ Kf7 37. Qxg4 Ke7 38. Qe6+ Kd8 39. Qd6+ Ke8 40. Qc7 Kf8 41. Qd7 b4 42. Ne6+ Kg8 43. Qg7#

Jan-27-09  rwbean: I checked with the human player in this game, and it is indeed this game where DT announced "mate in 19".

Interestingly, both this game and the Lesiege game in the same tournament end with a move that forces mate in at most 14.
