Resignation Trap: TRAGIC ERROR
<HK> White obtains a winning advantage by means of a magnificient breakthrough in the center. Eventually, he needs only one more move - a rather simple one - to make Black resign. At this point. however, White errs tragically, allowing one of Black's Pawns to queen.
9. 0-0 <SB> ! Foiling my plan! After the usual 9.e4 b4 10.Na4 c5! 11.e5 Nd5 Black would stand well.
10.Ne4 <SB> !
(after 12...Qb6) <SB> White has quite a lead in development...
15.Rac1 <HK> White has a promising game.
15...0-0 <HK> Castling behind the already broken Pawn front looks highly suspicious. Yet it is very hard to prove anything wrong with it.
17...Qd8 <SB> To assist in defense of the Kingside.
19.d5 <HK> !! A master-stroke in Alekhine's style solves the problem. White obtains a winning advantage.
19.d5 <SB> !
19...Bf6 <HK> After 19...Bxd5 20.e4! White has an irresistible attack.
<SB> 19...Bxd5? 20.e4 would be overwhelming.
23.Be2 <HK> !
24.Qxd8+ <SB> Black threatened ...Nc3 if White avoided the exchange of Queens.
25.Bf3 <HK> ! White's Kingside attack is broken, but his general advantage stands.
25...Ra7 <SB> ? The right way was 25...Nc3!! 26.Bxb7 Ra7 and wins!! (27.Bf3 Nxd1 28.Rxd1 Rad7 etc.).
26.Nc4 <SB> Black having missed a golden opportunity, White builds up the pressure.
