There was an interesting article in the New York Post written by Andy Soltis. It discussed a proposed rule by GM Vassily Ivanchuk that will force a player to move the queen if it is attacked. They give the line 1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Qxd4 Nc6. Now the Queen is “in check” and must be moved. In other words, 5.Bb5 is illegal because of 5…Nxd4.
I don’t particularly like this rule. The first reason is that I play the above line with white. 🙂 Secondly, this severely limits the power of the pin, an important tactic in chess. Third, what would happen if queen attacks queen?
What do you think of this variant and chess variants in general?
