(7) Gunsberg,Isidor Arthur - Piper,Thomas Henry [D05]
London Vizayanagaram Criterion, 1883
[Tourn book #258; Harding]
tourn book #258 has notes by Minchin, but these notes are mostly by Tim Harding for his book 'Eminent Victorian Chess Players.' (Some notes have been added since.) 1.d4
As played by Blackburne against Chigorin at Berlin 1881, but the bishop would be posted more aggressively on d3. [4.Bd3
By copying his opponent's formation, the Greenwich amateur has achieved a more or less equal position. Gunsberg chooses a move that induces Black to diverge from that strategy. 11.Ne5!?
and Black bust break symmetry because if 13...Nxc4
) ; 11...cxd4!
would pose an awkward choice 12.Bxd4
and White will have to accept hanging pawns or an isolated d-pawn.) 12...Nxe5
when White's piece co-ordination is poor] 12.dxe5
Gunsberg's bluff succeeds and he now obtains the initiative. [12...Ne4
would be the way to attempt to continue symmetrical play, although instead of taking the knight White would probably play 13.Rc2
White's major pieces will now come into play and Black can only defend. 14...Re8
TH: This move was criticized by Minchin. 17.Rf3!?
TH: This got a ! from Minchin [17.Nf3!
is better, to rule out Bb5 in some variations.] 19.Rg3
19...f6 is the lesser evil. 20.Qh5
This renews the threat of Qxh6 but is not the most precise way to pursue the attack. [21.Rd1
is a good preparatory move, placing the rook vis-a-vis the black queen and eliminating the looseness on the c1-h6 diagonal which could allow Black some counterplay. 21...d4!?
is another forcing continuation, threatening 22 e6. After the probably best reply 21...Be6
White can if he wishes win the exchange by 22.Bb5
Black overlooks the threat, losing a piece, and so justifies White's choice of move. The rest is easy for Gunsberg. [21...d4!
puts up the best fight, by closing the long dark diagonal. Yet White retains excellent winning chances, e.g. 22.Rf1
Improving the piece that is contributing the least (RR22.Nc4
was Gunsberg's idea but Minchin does not see any certain victory.) 22...fxe6
is sounder but 23.Nc4
threatens Nd6!) 23.f6!
loses a piece because after 24.Rxe3
the recapture 24...dxe3
allows mate by 25.fxg7+
and Black soon loses at least the exchange) 26.Qh4
followed by Ng5, with an enormous attack in return for the sacrificed pawn.; 21...f6
does not create a real blockade. White has two possible combinative continuations: 22.Bb5
when after (22.Bxf6!?
when White clearly stands much better but has no immediate win.) 22...Ree7
The only way to avoid immediate loss of material, but allowing the pretty 23.Qxh6!
and if 23...gxh6?
