Demon Pawn -
Quick Attack Opening. |
Vice Pawn Opening-
First Line. 1: P 8l-8k 2: P 10e-10f P-9f would be one alternative line here. But not 2: SE 5d-7f This makes it easy for black... 1: SE 5d-7f 2: VG 8m-6k 3: P 4e-4f 4: Fi 7n-9k 5: SE 7f-9f (or P-9f) 6: Fi 9k-6h and Fix9e or 8e is nasty. Another alternative is 2:SE 5d-3f... 1: SE 5d-3f ... a). 2:VG-6k now would transpose into the main line. b) 2: SE 5m-3k Trying to make VG-6k count 3: P 4e-4f Making sure VG-6k is a non forcing move. 4: SE 12m-14k In that case take the sting out of P-10f 5: P 10e-10f 6: P 13l-13k Not needed yet, but both sides are preempting 7: BG 11d-9f 8: VG 8m-7j - The VG here forms a shield for the black Fi-7k if wanted and stops whites Fi-11f c). 2: VG 8m-10k Not a good move. 3: P 10e-10f 4: SE 12m-14k 5: BG 11d-9f 6: P 13l-13k 7: RG 10dx10k 8: P 10lx10k 9: Fi 10c-11f and white stands better. d}. 2: VG-7j now Ln-8m is forced in reply to P-10f. If white then plays VG-13h to win the Fi, black plays VG-4i. Forking mate and taking a Fi in sente. 3: SE 12m-14k 4: BG 11d-9f 5: P 13l-13k 5: SE-16i Must be bad... 1: SE 14k-16i 2: Fi 10c-11f What does black do now? if... 3: P 13l-13k 4: Fi 11f-15jx!1 The Fi is safe 5: WB 11nx15j Makes matters even worse 6: VG 9dx15j mate 6: P 8e-8f If instead.. 1: SE 5d-7f 2: VG 8m-6k 3: P 4e-4f 4: Fi 7n-9k ( SE-6f seems fine here) 5: VG 9d-11f (This is correct AFTER Fi-13i) 6: Fi 9k-6h Now white has big problems 7: RG 7dx7m+ Reducing the pieces to be burnt. 8: FE 8nx7m (Not Lnx7m, the 8n square is needed) 9: SE 7f-8f 10: Fi 6hx7ex!5 11: Fi 7cx7e 12: GG 9m-8n Mate If this square was not free GG-8m would be met with Fix7lx!6 7: VG 8m-6k 8: SE 5d-3f 9: Fi 7n-9k Var: HF 4m-4k If instead.. 1: HF 4m-4k 2: BG 9f-10g 3: VG 6k-4h 4: P 4e-4f 5: VG 4hx8d* 6: Ky 7b-5b 7: Fi 7n-9k 10: RG 7dx7m+ 11: Ln 9ox7m 12: HF 4d-4f 13: Fi 9k-13gx!1 Var : Fi-7j If instead.. 1: Fi 9k-7j (Main threat is Fi-4gx!3) 2: Fi 7c-7f easily met. 14: VG 9d-11f 15: VG 6kx11f 16: Fi 10cx11f 17: Fi 13gx11fx!3 18: LH 8cx11f - White is happy with this. Demon Pawn - Double doors 1: P 7l-7k 2: SE 5d-3f 3: P 9l-9k 4: P 10e-10f 5: SE 12m-14k 6: P 8e-8f White must not play BG-9f here e.g. 1: BG 11d-9f 2: VG 8m-14g 3: VG 9d-11d 4: VG 14g-13i 5: VG 11d-11g 6: VG 13i-15h 7: VG 11g-11d 8: Fi 7n-14g 9: VG 11dx15h* 10: Fi 14gx14ex!5 7: HF 4m-4k Now White must play 8.BG-9f or 8.P-4f or something similar but not the original move given here, 8.HF 13d-13f ??? Black has a great answer to that (discovered by Guenther Mensching) The original position is given as a problem below. Centre Eagle Opening - Bishop General counter. 1: SE 12m-10k 2: P 10e-10f 3: P 13l-13k 4: BG 11d-10e Mate threat. - Instead, white could play 1: SE 5d-7f 2: P 7l-7k 3: P 4e-4f 4: BG 6m-7l 5: SE 7f-6g 6: BG 7l-3h now 7: RG 7dx7m* What if white takes this suicide exchange. (P-7f was best.) 8: Fi 7n-6m 9: HF 13d-13f 10: Fi 6m-9k Forks 13g, 9e and 6g. or white could play 1: VG 9d-14i 2: SE 10k-12i 3: VG 14ix10m* 4: P 7l-7k 5: SE 5d-3f 6: VG 8m-4i Forked 5: SE 10k-11j Interesting defence, covers many vital points 6: BG 10e-14i To win exchange and trap the Fi or get a free move. 7: P 7l-7k 8: SE 5d-3f 9: P 10l-10k 10: SE 12d-14f Stops GG-14h - Example to show the power of GG-14h. 1: Fi 10c-11d 2: GG 9m-14h Threatens mate on 14g, 15h and 1h. 3: VG 9d-13h No good but just for show 4: SE 11jx13h 5: SE 12d-14f 6: GG 14h-14g 7: SE 14fx14g 8: VG 8mx14g Mate 11: HF 4m-4k If instead 1: BG 11m-6h (Too early) then 2: Fi 10c-11d 3: HF 4m-4k 4: Fi 11d-11g 5: BG 6hx10d+ 6: Fi 11g-11ix!1 7: +BG 10dx9d 8: FE 9cx9d 9: Ky 10o-12o 10: Fi 11ix9lx!5 11: LH 9nx9l 12: GG 8d-9c 13: K 9p-10o 14: GG 9c-10c 15: K 10o-9p 16: GG 10cx10n. 12: HF 4d-4f A tense game, unsettled. |
