Nice - back and forth a bit though
rooks on the seventh...
4. Rxc7 Bc5 doesn't convince me
Very interesting... Pachman doesn't consider that move (and neither did I)... is it a refutation?
What am I missing? 1 Rf8#......
Ah, I'm missing the Black Rook. Carry on, I'll get my coat.....
I think you put the eye-patch over the good eye!
Heinzie, after 5. Rxc7 Bc5, white has the simple 6. Rh8#. The example is sound, I'm pretty sure. Black's own pawn on d4 blocks the more effective 5 ... Bd4.

it's 4.Rxc7 Bc5 5.Rh8+ Bf8 ... the Bishop interposing on that mate is the point of Bc5.
Someone put this thing in an engine and tell me if white has an answer for Bc5... I'm going to play basketball or I'd do it myself... my guess is that Heinzie has refuted the diagram... I've found some other lines in Pachman's book that fell to analysis. (Doesn't bother me, honestly. Still a very good book!)
Okay, my mistake. I missed that we were talking about the Ke8 line. I'm using chesslab.com's engine, which doesn't seem too strong, but with its help, here is what I came up with. It, interestingly, thinks that after Ke8 white has about a 4 pawn advantage. However, after Ke8 Rxc7?? Bc5, black's advantage is substantial. Here is what we (and apparently Pachman) missed: an intermediate move!
Hopefully this helps to solve the problem. Heinzie, my apologies for the misunderstanding.Okay, my mistake. I missed that we were talking about the Ke8 line.

Ahhh! Beautiful! Bringing the King back to f8 defuses Bc5! Honestly engines get a bad rap -- yes, they play some ugly weird moves sometimes, but they find some beautiful resources too. I mean I feel like that engine line has taught me something useful and valuable about this position that Pachman failed to note. Goodfind, honorflamingo!
A simple study from Pachman's Modern Chess Strategy about the power of rooks on the seventh...
