Pirc perpetual

by Oliver Reeh
2/14/2020 – In the diagram White played 8.e6 fxe6 9.Ng5 threatening both 10.Nxe6 and 10.Qxg4. So, fire on the board — can you extinguish it as Black?

Sharing the point

The days short undecided games between masters were respectfully called "grandmaster draws" are gone. The "Sofia rules" — a good invention for sponsors, spectators and perhaps even the players themselves, don't you think!?

This “Sharing the point” concept is introduced as it was the key of "Sofia rules" as “good invention” against the "grandmaster draws".

I’m nobody but it is much more the "complex approach" key of the tie-break format in my ten years old proposal: https://sites.google.com/site/pcmorph72/articoli/wcc-cycle

I explain myself: in this “Pirc perpetual” Oliver Reeh’s example, if White allows Black to draw with 11.Nxd8 (instead of 11.Nxb5), it means that White deserves a "grandmaster draw" demerit while Black deserves a "tie-break" bonus, because White had the first-move advantage and Black proved a better opening preparation. Of course, it would not have been the same thing if the perpetual occurred much later, in middlegame or after move #40 or in endgame, i.e. when the draw is not due to Black’s preparation but much more probably to an equivalent contrast of equivalent preparations, so the number of the move when a draw occurs (in this case 11) should be taken into account.

Instead of a forced “Pirc perpetual” with 11…Bf2+ I took as example an Alekhine perpetual with 11…Qe8 (after 1.e4 Nf6 2.e5 Nd5 3.d4 d6 4.Nf3 g6 5.Bc4 Nb6 6.Bb3 Bg7 7.a4 dxe5 8.a5 N6d7 9.Bxf7+ Kxf7 10.Ng5+ Kg8 11.Ne6) but the key concept is very the same.
