Sicilian Paulsen / Pin Variation/ Koch Variation
1.e4 c5 2.Nf3 e6 3.d4 ( the best move here 3c4 sometimes becoming a Marozy Bind) 3...cxd4 4.Nxd4 Nf6 5.Nc3
Bb4 (5...Qc7 is best here Why?)
6.e5 Nd5 7.Bd2 Nxc3 8.bxc3 Ba5 (9. Be7 is book and best here)
9.Qg4 0-0 10.Bd3 Qc7 11.Qe4
(If White castles here 11.0-0 black is attacking the pawn on e5 and c3 but it is a bluff if black grabs the pawn 11...Qxe5 he gets int trouble as in game 2)
11... g6 12.0-0 (Maybe 12. Nb5) 12...f5 13.exf6 Rxf6 14.Bg5 (again 14.Nb5! to get a grip on the Black hole at d6.) 14...d5
15.Qh4?! Rf8 16.c4 Nc6 17.Nb5 Qe5 18.f4!! (A strong move attacks blacks Queen and prepares
for a Kings side assault)
18...Qe3+ 19.Kh1 (19.Qf2 would get the queens off and give White a won game) 19...Qc5 20.Bf6
White has a advantage but goes for a draw because he is in time trouble. After this move ,there is little Black can do to
avert White's attack which forces a draw.
20...a6 21.Bxg6 (21. cxd5 attacks blacks knight would win)hxg6 22.Qh8+
22...Kf7 23.Qg7+ Ke8 24.Qxg6+ Rf7 25.Qg8+ Rf8 (Black loses his Rook if he tries to block with the Queen because of whites
knight)26.Qg6+ Rf7 27.Qg8+ Rf8 28.Qg6+ 1/2-1/2 Please click through this Game 1 below
