Hi All,
Here is the lesson of the day by Chessmaster XI : How to play and win with the Scotch Mieses, 8.c4 Ba6 9.b3. This is a game versus Delphil 2.9b long time control 40/120 + Rest 60.
[D]r3kb1r/p1ppqppp/b1p5/3nP3/2P5/1P6/P3QPPP/RNB1KB1R b KQkq - 0 9
Garry Kasparov played this variant with success in 2005 versus French GM Etienne Bacrot.
9...g6 10. f4 Qb4+
[D]r3kb1r/p1pp1p1p/b1p3p1/3nP3/1qP2P2/1P6/P3Q1PP/RNB1KB1R w KQkq - 0 11
Now Chessmaster XI Aiglos II and Delphil 2.9b are out of book.
CM XI Aiglos II choosed to play like Kasparov 11. Bd2 that threaten black queen and still protect the f4 pawn.
[D]r3kb1r/p1pp1p1p/b1p3p1/3nP3/1qP2P2/1P6/P2BQ1PP/RN2KB1R b KQkq - 0 11
Delphil played 11.Qb6 like Bacrot.
[D]r3kb1r/p1pp1p1p/bqp3p1/3nP3/2P2P2/1P6/P2BQ1PP/RN2KB1R w KQkq - 0 12
In the position above, Kasparov played 12. Qe4 but Chessmaster XI Aiglos II prefered to play 12. Qf3.
[D]r3kb1r/p1pp1p1p/bqp3p1/3nP3/2P2P2/1P3Q2/P2B2PP/RN2KB1R b KQkq - 0 12
After 12...Nb4 13.Kd1 Chessmaster decided to play King in the middle.
[D]r3kb1r/p1pp1p1p/bqp3p1/4P3/1nP2P2/1P3Q2/P2B2PP/RN1K1B1R b kq - 0 13
After 20.Kc2 Chessmaster XI King Safety's is secured, now it's time to go for battle !
[D]1r2k2r/pbppbp1p/nq4p1/2pNP3/2P2P2/PP3Q2/2KB2PP/1R3B1R b k - 0 20
In the position bellow Chessmaster just played 23.h4! and the black king is already trapped.
[D]4rrk1/p1ppbp1p/nq4p1/2pPP3/2B2P1P/PP3Q2/2KB2P1/1R5R b - - 0 23
Then it's just a matter of technik for Chessmaster XI that played 26.e6! in the diagram bellow :
[D]1n1brrk1/p1p2p1p/1q1pP1p1/2pP3P/2B2P2/PP3Q2/2KB2P1/4R2R b - - 0 26
Then 27.hxg6 and Blacks resigned
[D]1n1brrk1/p1p4p/1q1pPpP1/2pP4/2B2P2/PP3Q2/2KB2P1/4R2R b - - 0 27
Nice isn't it ?
