Black to move. How should Black proceed?
Source: ChessToday.net
First glance:
1. …Qg3 (threatening Qxg2 mate)
If 2. Rxg3 Re1 and mate next move.
Shouldn’t be any counter for it.
R:g2+
1…Qg3!!…
If 2.Rxg3 Re1+ 3.Rxel Rxe1 mate.
If 2.Ne3 Qh2 3.Kf1 Qh1 mate
Qg3 RxQ
Re1+ RxR
Re1++
Qg3!
1….Qg3! 0-1
Well, the rook at f3 is pinned, else Re1 would be mate after an exchange of rooks. So Qg3 looks like the right move. It threatens Qh2 mate, and the pinned rook can’t take it.
1. Qg3 (with an idea of 2. Qxg2#) … Rxg3 2. Re1+ Rxe1 3. Rxe1#
Qg3+!!
Black should defend his a-pawn by a6, and thus commence a queenside minority attack.
From Spain…
1)…,Qg3 win and 2)…,Qh2+
1)…,Qg3
2)Rg3,Re1+
3)Re1,Re1++
1. … Qg3
a) 2. Tg3 Te1+
3. Te1 Te1++
b) 2. Tf2 Qh2+
c) 2. Qf2 Qh2+, Qh1+ and Nh2++
….. Ne5
Rf1 Nc6 (if fxe5 dxe5)
Qmoves Rxb2 wins
…Qg3! 2. Rxg3 Re1+, etc. ; 2. Rf2 Qh2+ 3. Kf1 Qh1; 2. Qf2 Qh2+ 3. Kf1 Qh1+ 4. Qg1 Nh2
1.-Qg3 (2.Rxg3 Re1+ 3.Rxe1 Rxe1++) 2.Ne3 R8xe3 3.Rf2 Qxf2+ 4.Kh1 Qxg2++
Not all mating combinations have to begin with a check.
The Rook on f3 cannot leave the f-file because of 1… Re1+. Black takes advantage of that:
1… Qg3!
Black threatens 1… Qxg2#. If White takes the Queen with 2 Qxg3, Black has a mate with 2… Re1+, 3 Rxe1 Rxe1#. Defending against the mate with 2 Rf2 or 2 Qf2 is met with 2… Qh2+, 3 Kf1 Qh1#. Other than stall mate by making a few checks, White can’t do anything.
Note that direct moves don’t work:
1… Re1+, 2 Rxe1 Rxe1+, 3 Rf1, and now Black doesn’t have time for 3… Qg2 because of the simple 4 hxg4.
Also, the flashy 1… Rxg2+ gets nowhere after 2 Kxg2 Re2+, 3 Kgh1.
Peter Biyiasas was the man who housed Bobby Fischer for long periods of time in the 1980’s and is one of the few people who played chess with Fischer between the Spassky matches, reportedly losing 17 speed games to the mad genius in 1981.
Deflect Rf3 from covering Rf1.
1. … Qg3 (threats Qxg2#)
2. Rxg3 (what else?) Re1+
3. Rxe1 Rxe1#
