2 queens

Post by Lyudmil Tsvetkov » Fri Jun 20, 2014 4:45 pm

I have a theory that 2 queens perform better than what their nominal values would suggest, as they are very fast and represent a force difficult to match. Coordination between 2 queens is unseen of in chess with other pieces.

However, most people seem to be of the opposite opinion, and some could even penalise a second queen. So I submit this moot question to your judgement.

[d]5rk1/1p3ppp/p1b5/8/8/4Q3/1P3PPP/6K1 w - - 0 1
An absolutely equal position Q vs R+B+pawn.

[d]5rk1/1p1q1ppp/p1b5/8/8/2Q1Q3/1P3PPP/6K1 w - - 0 1
We add one queen each side. Who has the advantage now? (of course, Qg7 will not be considered)

[d]5rk1/1p1q1ppp/p1b3n1/8/8/2Q1Q1N1/1P3PPP/6K1 w - - 0 1
Adding more pieces to obtain a more realistic position. Who has the advantage now? (of course, adding pieces usually helps the side with more pieces, i.e. black, but that is a special case)

Maybe someone could post engine output on the above positions to help resolve the dilemma.

I myself would give some 50cps additional bonus for 2 queens, if not more.

In any case, in all the games I have seen with 2 queens, the queens have prevailed.

What is your opinion, are 2 queens an asset or a liability?

I was looking on the net about chess games with more queens, not many available with a good content (i.e., one side having decisive advantage, promoting queen just before mate, etc.), but here is an interesting one.

Actually, the side with more queens lost this one, but I think white made a mistake somewhere, actually, I think many mistakes.

In Capablanca Chess you have three Queen-class pieces each. The first Queen is clearly superior to R+B, like in normal Chess, but if the Queen is the second super-piece it is about equal, and when it is the third, the Rook + Bishop have a clear advantage.
