This gem throws some lights on the difference between fake development and real development.
The checkmate Patterns covered are:
1. Queen on h6, bishop on b1-h8 diagonal and no defender of f7.
2. Queen h6 and rook along the g file
I am aiming to present this game only to show how it can be used to teach kids:
Tarrasch, S – Mieses, J [C10]
1.e4 e6 2.d4 d5 3.Nc3 dxe4 4.Nxe4 Nd7 5.Nf3 Ngf6 6.Bd3 Be7 7.0–0 Nxe4 8.Bxe4 Nf6
Q : Is it good to exchange a light square bishop for a knight?
A : No, it is a good Bishop and very active one, compared to its counterpart.
Q : Is it right time to play b6 in order to develop bishop?
A : No it is not the right time to play b6 as now White can play very energetically, hindering the development of black’s light square bishop and castling. The immediate 0–0 was better.
Beginners have been advised to not to move same piece twice in the opening. But in chess there are no universal rules, even though you can create many rules for better playing. Similarly any Bishop move here would be development for the sake of development. However, with the knight on e5 White is able to make Black’s development very difficult.
10…Bb7 11.Bb5+ Kf8 costs Black his right to castle.
11.Nc6 Qd6 12.Qf3
Q: Can Black play Bb7 ?
A: No, because Nxe7+ wins a piece. Thus Black is forced to play Bd7 and now we can see that with careful play White manages to take the driving seat.
12…Bd7 13.Nxe7+ Qxe7 14.Bg5 Rac8 15.Rfe1
Q : What is the idea behind Re1?
A : A rook lift. Via this rook lift white brings one more piece into the attack, a very important idea to remember.
15…Rfe8 16.Qh3 Qd6
If 16…g6 17.Qh4 Kg7 18.Re4 or 16…h6 17.Bxh6 gxh6 18.Qxh6, and Black is paralysed.
Q : Would it be good to play Qxh7 or there is something better? Try to see the reasoning behind Black’s Qd6 move.
A : It is good but there is a much better move in Qh6. This is because black’s idea is to find shelter on e7 and try to generate some counter play on g and h file. Black is also trying to protect the g7 square with Qxd4.
This is typical mating pattern, a queen on h6 and bishop on b1–h7 diagonal with no defender of f7. For example 18…a6 19.Bxh7+ Kh8 20.Bg6+ Kg8 21.Qh7+ Kf8 22.Qxf7#, which is a pattern you should study more closely. Coaches should provide more examples on the same theme.
18…f5 19.Re3 Qxd4 20.c3
In order to prevent checkmate the Black queen has to stay on the a1–h8 diagonal. But now there is no good square to stay on so Black has to sacrifice the queen. Instead he choose to throw in the towel.
Better was 20.Rg3+ Kh8 21.c3 Qe5 22.f4 and its over.
