NOTES. 



(a) This move still holds the field, in spite of 4. P to Ko, which 

 took the popular fancy for a time after Steinitz's celebrated Habana 

 game. 



(/') This used to be the way in which the German players usually 

 met Blackburn's French Defence. 



(f) Black may castle here ; P to R3 is not essentially necessary at 

 this point. 



(d) The proper square to place this Knight is K3 via Qsq. 



(c) White seeks to plant his Knight at Q4. 



( /) White posts his forces in advantageous positions. The Rook 

 on B2 anticipates an attacking design on the QKtP, and is also avail- 

 able for the support of an attack on the King's side should P to KKt4 

 become feasible. 



(<;;) A promising venture. White's position is admirably contrived, 

 as he has nothing to fear from Black. 



(A) PxP 27. PxP, P toKt3 would also have left White a prepon- 

 derating advantage. 



(i) Threatening KtxBP, and thereby bringing his Queen into 

 better play. 



(l) R to KBsq would have been met by White with 29. PxP, 

 KtP x P 30. R to Kto, R (Kt2) to Ktsq, 31. R CK2) to Kt2, R to Ktsq, 

 Kt x BP all the same.

(0 KPxP would be followed by P to K6 and Q to K5 (ch). 

 (»)) With K to Bsq Black might have held out longer, 

 (ii) As effective as it is pretty. If PxKt 33. Pto KO, then the 

 check on Q4 kills Black. 



O) If R to Qsq 35. Q to B7, threatenmg Q x R.

XOTES. 



(a) The move commits Black to an attack on the King's side, 



because it leaves his Queen's wing weak for the end game. Indepen- 



dent of this question, I think Black should not play B to KKt5 before 

 ^Vhite has moved his KP. 



(b) Experience has not yet confirmed this move sufficiently. In 

 advancing thus early, the Knight is exposed to wind and weather. 



(!•) P to K3 followed by B to Q3 might be employed to better ad- 

 vantage than the test move. 



(rf) White does not get much comfort out of this move. This is 

 the second time this Knight has attacked the Bishop on a square from 

 which he will have to retire. 



(«) White does not seem to have any settled plan of action, and is 

 losiin; ground in consequence. 



( /■) This move adds to the list of wasted opportunities for making 

 developing moves. 



(g) All this helps Black, whose Bishop is better posted on B2 than 

 Kto. 



(h) This move adds additional weakness to White's game. 



(i) It matters little what White does, as his game is hopelessly 

 compromised, but this move facilitates Black's advance in the 

 centre. 



(J) Black evidently intends to advance on the KB file and B to 

 Ksq. While preparing for this, also threatens other contingent 

 dangers, such as Kt to Q5, &c. , which, under circumstances, 

 might become dangerous. 



(/) If I had to illustrate the meaning and importance of losing 

 time I should chose the moves of the Knight in this game as a good 

 example. Out of 21 moves made. White has made 6 ineffective 

 moves with this Knight, and has now again reached his starting- 

 point, namely, 1. Kt to KB3, 2. Kt to K5, 3. Kt to KB3. 4. Kt to 

 KR4, 5. Kt to KB3, 0. Kt to Ktsq. 



(/«) Black increases his advantage with every move. 



(n) Even if White had guessed the beautiful combination which 

 Black was working out, he could do little else except Q to Qsq. 



(o) A surprisingly fine conception. Of course if B X Q, mate in two 

 follows. Diagram appended.
