Capablanca's one loss in tournament play during the period between 1914 and 1924
Capablanca:
"29.Qxb4 [The position looks most interesting.]
29...Rcg8 [I thought it would be possible to get up such an attack against
the White King as to make it impossible for him to hold out much longer, but I was wrong, unless it could have been done by
playing 29...Bc6 first, forcing 30.g3 and then playing 30...Kh5 I followed
a similar plan, but lost a very important move by playing 29...Rcg8, which gave White time to play 30.Rd1. I am convinced, however, that 29...Bc6 at once was the right move. White would be forced to
play 30.g3, and Black would reply with either 31...Kh5 as already indicated, which looks the best (the plan, of course, is
to play 32...Rh8 and follow it up with ...Kg4, threatening mate, or some other move according to circumstances. In some cases,
of course, it will be better to first play ...Kg4), or 31...Ne4, which will at least give him a draw."
My notes: Feb-26-2010
A) 23...Rc7 might be an improvement for Black. Who knows - it might have been
good enough to extend Capablanca's winning streak.
