An' amusing skirmish, -which was recently plaved : — 

 Ieregclae Defenxe IX THE Algaiee Gambit.

ENDING FROM ACTUAL PLAT. 



The following position occnrred in a game played at the City of 

 London Chess Club. Black baring giren the odds of Pawn and 

 move. White plared 1. R to 

 K 8Q. (ch), K to B sq. This 

 more illustrates the great im- 

 portance of timing the mores in 

 End-games. Either K to B2 or 

 B3 would be less good, i.e., K to 

 B3. 2. R to K6 (cb), and 

 whether Black plays Pi x E or 

 K X P White wins, for if K x P 

 White Queens in eight mores, 

 while Black wants nine moves. 

 Or if ExR, 3. PxR, K to K2. 



4. P to R5, and wins. Again, 

 if Black replies K to B2, then 

 2. R to KG likewise gives White 

 an advantage, although barely 

 sufficient to win. 



After 1. R to K sq. (ch), K to 

 B sq., the game proceeded : 

 2. E to KG, E X R. 3. P X E, 

 P to Kt4. 4. K to Q6, K to K sq. 



5. P X P, P X P. G. K to B5, K to K2. 

 B4, K to B4. 9. K to Q3, K to Kt4 

 11. K to B3. K to E5. 1 



Whitb. 

 A. HooKE. 



K X P, K X P. 8. K to 

 10. K to K2, K X P. 

 K to Kt2, and the game is drawn. 

 The following is also an instructive variation : — 1. Rto K sq. (ch), 

 KtoB3. 2. R toKG (ch), KxP. 3. R x E, P x E (ch). 4. K x P, 

 K to K3. 5. K to Kt6, K to Q4. G. K x P, K to B4. 7. K to Eo, 

 K to B3. 8. K to Kt4, K to Kt3. 9. K to B4, and again ^Yhite 

 must Queen his KEP. 



NOTHING NEW UNDER THE SUN. 



The following note from " Skrani " appears to be of some in- 

 terest : — In the American " Synopsis," appears the " Stone- 

 wall " Opening, the moves beine 1. P to Q4, P to Q4. 2. P to KB4, 

 P to K3. 3. Kt to KB3, Kt to KB3. 4. P to K3, ic. This is so 

 far from being a novelty that I find it, with the first two moves of 

 White transposed, in several of the De la Bourdonnais-ilacDonnell 

 games, the former master playing the attack. 



In tiie same book "Bird's attack" in the Giuoco Piano occurs, 

 the Frenchman being again the experimentalist, but losing. I aIsc^ 

 discover here one of Mr. Mason's favourite developments, viz., 

 1. P to Q4, P to Q4. 2. B to B4, which, if my memory serres me, 

 was stated by so good an authority as the Field to hare been in- 

 troduced by Harrwitz. I also think I remember that the Opening 

 1. Kt to KB3 which I call (and I think rightly) the Znkertort 

 Opening (for he it was who made it workable in first class practice) 

 was described by the same authority, as the inrention of one of the 

 players in the Paris Tournament of 1867. It will, howerer, be 

 found in an important match game so far back as 1851, llr. 

 Staunton being the aggressor, and Mr. Williams the defendant. 

 See " Chess Tournament," page 152, for the mores, 1. Kt to KB3, 

 P to Q4. 2. P to Q4, P to K3. 3. P to QB4, P to QB4. 4. P to 

 K3, Kt to KB3. 5, Kt to QB3, Kt to QB3, 6. B to K2, &c. 

 Truly the ancients have stolen all our best thoughts 1 Perhaps 

 someone can carrv these moves even further back.

E. LocDEN, H. A. NisBET. — Solutions of Problem No. 157 corect. 



E. W. YorxG.— To refuse to take the P after White's seventh 

 more, P to K5 in tiie Muzio Gambit, has often been played, but 

 with less success for Black than Q x P. If Q to B4 in.?tead. White 

 replies with 8. Kt to B3 (threatening Kt to K4 and BG). If Black 

 replies with QKt to B3. 9. Kt to Q5, Kt x QP. 10. Kt. x P (ch), 

 K to Q sq. 11. Q to B3, and Black has an awkward position. We 

 should, howerer, be pleased to publish yoor analysis.

Importation of IxFEcnors Disease ixto Londox. — Vigorous 

 steps are being taken to prerent the introduction of infectious 

 disease into London by the waterway of the metropolis. The Port 

 Sanitary Authority has recently drawn up stringent regulations 

 regarding the method of arresting the importation of eight specified 

 diseases, and these hare been approred of by the Local Gorern- 

 ment Board. Erery person in charge of a ship having dangerous 

 infectious disorder on board is to stop at Graresend, and send 

 notice to the medical otiicer of the Port Sanitary Authority. The 

 ship is to remain moored until she has been boarded by the 

 medical officer, who shall, if necessary, order the remoral of the 

 patient to one of the hospitals of the Port Authority. Similarly, 

 if disease breaks out after passing Graresend, the person in charge 

 of the ship is to gire notice to the Port Authorities at Greenwich, 

 who are to follow a similar course. Masters of ships who fail to 

 comply with their order are to be fined £5. We commend these 

 simple regulations as admirable substitutes for quarantine, —
