White retreated his attacked Rook with 42 Rb3. and lost. This game was played decades before the Vancura position was published posthumously in 1924. The key idea is revealed after 42 Rb5+ Kd4 43 Rf5! a4 44 Rf4+ Kc3 45 Rf3+

Likewise the Vancura insight explains why in this position:

45..a4 was a mistake, allowing Black the option of 46 Rf3! = Instead, 43..Rd2! 44 Rb5 a4 wins. The same possibility was allowed after 46 Rb8 Ke3 (46..Rd2!) when White has 47 Rb4! followed by Rf4-Rf3.

The drama continued unabated:

Black chose 47..Kd2 (any other legal move wins) allowing the manoeuvre 48 Ke4! a3 49 Kd4 Kc2 50 Kc4 =. In the game continuation, 47..Kd2 48 Re2+ Kd1 (48..Kd3 -+) 49 Kf2? was played. Instead, White can again make a draw with 49 Rh2 Ra3+ 50 Ke4+ Kc1 51 Kd4 Kb1 52 Kc4 Rg3 53 Kb4 a3 54 Ka4 =

One wonders whether Josef Vancura knew of and studied this game. Given its remote location, in all likelihood he discovered the Vancura concept independently.

Jul-12-21  optimal play: <<<<<CHESS.>


The principal feature in the play so far has been the fine form shown by Mr. J. L. Jacobsen, whose score to date is 3 wins 0 losses.

His opponents were W. J. Miles, A. E. N. Wallace, and Dr. L. B. Lancaster.

We give the score of the Jacobsen-Wallace game, which will be found to contain play of a high order and to be well worthy of careful study and analysis.>

<(a) 12. P to K 4 <12.e4>

Isolating the Q P, which leads to trouble later on.>

<(b) 16...Q to Kt 3 <16...Qb6>

A fine move, beautifully followed up.>

<(c) 18. K to R sq <18.Kh1>

It is clear that P takes B would not pay, because of the reply R takes P.>

<(d) 22...R to Q 7 <22...Rd2>

Threatening mate on the move by B takes P.>

<(e) 33...R to Q 2 <33...Rd7>

The "sealed" move at the adjournment after the first evening's play.>

All through the game Mr. Jacobsen's play is masterly, and his conduct of the ending is most interesting and instructive.>
