| nasmichael: By move 32, black holds 2 sets of doubled pawns and white controls 2 rooks + 5 pawns against R + N + 7 pawns. Marshall holds him off anyway. Masterful fight in the end with Q + P vs Q. |

| Karpova: Position after 58.Qf7:
<Thus, there are two main drawing ideas for White – either get his king in front of the pawn (when all K+P endings will be drawn), or, if that is impossible, get his king to the “north-west” corner, ie. to the drawing zone on a7-a8-b7-b8. Once we understand this, the moves already make sense, and many of our standard questions can be easily answered. Since his king is already quite close to the pawn, the first drawing technique is more appropriate, hence at move 59, 59 Ke2 draws more easily. Lasker instead chose the other technique, heading North by North West. As the game went on, why did Black retreat his king to g6 between moves 66-68? Answer: to get nearer the White King, and thereby increase the chance of cross-checks (answering a check with a check). Why is 71 Ka4?! dubious? Answer: because the WK is moving away from the drawing zone. In the note to White’s 74th move, why is the position after 74 Qd7? Qf4+ 75 Ka3 Kg5 winning for Black? Answer: because the WK is cut off from the drawing zone.>

| Eyal: Queen endings are notoriously difficult to play, even for top players (e.g., the comedy of errors in Topalov vs Anand, 2005). In the present game, Lasker seems most of the time to know what he is doing - getting his king to the "drawing zone" etc. - and yet he slipped on move 80 (as <sucaba> points out - playing 80.Qc1 instead of Qh1), and could have lost if Marshall had played 81...h3 or Kg7 instead of Qf6+. But how can you figure such things out without a tablebase - or the accurate calculation of 25-30 move long variations? |

| WhiteRook48: it does need to be pointed out that these guys did not have tablebases |
