 NOTES BY MEPHISTO. 



(") Tho defence of P. to y.R.3. jnstly deserves preference to the 

 move in the text. It leads to a safe development, for after 



4. ^ .", ', . 5.-,- — —^ ~, this Knight, on being attacked, can 



Kt. to K.B.3. Kt. takes P. 

 retire to B.t., attacking tho Bishop, and thereby gaining time. 



C") This move must be condemned on principle ; it blocks Black's 

 game entirely. Kt. to K.B. 3. is the proper move. 



{') This move, which to some might look rather strange, was 

 played to prevetit Black from Castling on the Queen's side, as that 

 was his intention ; it will be seen that tliis, though only a small amount 

 of forethought on the part of White, opened the door to a large 

 amount of luck. 



C) As pointed out bj' the Sonntagshlatt, it would not have been 

 feasablo for Black to play 9.P. to K.Kt.3 with the intention of pre- 

 paring to Castle on the King's side, as White would have replied with 



10 



B.toK.Kt.i 



Kt . to Q.-t 

 ' P. takes B. 



Kt. takes B. 



and the Queen cannot 



■p.toK.B.3. 



retake on account of R. to K.sq. If in reply tolOB. to K.Kt.S.BIack 

 should play Q. to Q .2., then White continues with bTTo^B.G. Black's 

 best course would have been to play P. to Q.11.3. and then Castle. 



{") Taking proper advantage of the position. The Knight back to 

 Q.3. was about the only thing to save tho Pawn, for if P. to Q.Kt.3., 

 then the Pawns on the Queen's side would be weakened still more by 

 g. to R.4. 



(') Tho idea of Black in giving up the Rook's Pawn was to play 

 Q. to Q.Kt.5, thinking that the Bishop would bo compelled to retire, 

 wliich Black would follow up by B. to Q.B.I, getting an attack. 

 Checking with the Qnoen would obvieuslv have been bad, i.e., 

 „ Q.takesH.P. .., Q. toR.fi.ch. ,., Kt. tok.S.ch. , „., ■. 



ll.i- - - - l-^-— i'-r-r. .) ^•^■x.- , -u-- and 'iV hito would 



Q.toQ.kt^). K.toQ.2. K.toK.sq. 



lose a piece. Black, however, overlooked tho force of 12. Kt. to K.5. 

 at onco, which i)rovcd fatal. The wliolo idea of Black of e.vposing 

 himself to the great danger of the position, for tho purpose nf 

 extricating his game, was unsound. In chess, as in everything else, 

 you must not indulge in such risky speculations ; no move ought to 

 be made but what a sound judgniont would ai>prove, as otherwise 

 an unseen danger, or an overlooked resource, is almost sure to aid 

 your adversary in demolishing your unsound speculation ; though 



in many instances, it might be highly ingcnioos, and, in a few 

 instances, might succeed,— only as an exception to prove tho rule. 



(«) There is notliing to save Ithick'i gamo. This is a remarkable 

 collapse of a lirHt-class player, of which there were a go'jd many 

 instances at Berlin. Dr. Schmid played Black, and we apprehend 

 ho must have also looked block, after White's 12th move —a rather 

 remarkable instance of a Smith tnming into a Blacksmith doring 

 a chess game of 12 moves. 



Problem Xo. 11. Hy Herr Gunsbcrg. 

 (From the " Westminster Papers.") 



White. 

 White to play and mate in three moves. 



Solutions of problems 6, 7. and 8, bv G. W. Middleton, T. H. 

 Symington, J. K. L., Gamma, Try Try Again, S.D.P., R.M., After- 

 noon, Etoniensis, correct. Of problem 8, by J. A. Miles, Arcadian, 

 and See Saw, correct. 



Alpha Beta. — The solution you send of problem 5 is based on an 

 incorrect idea as to the nature of chess problems. When mate is 

 to be given in three moves, what is meant is, that against the best 

 possible defence White is to give mate on his third move. You have 

 shown how, after a certain move by White, and a certain reply 

 by Black, White can mate. But after White, l.B. to K.R.3., 

 Black can play Knight to K.R.S.ch., and there is no mate either 

 on the move, or in sevei-al more moves.
