This site does not allow e.p. moves to be executed at the start of a solution. Obviously, one cannot expect the program to "prove e.p. rights" but there is no reason not to trust the contributor of the problem/solution. One may expect him to explain in the accompanying text why it is legal.

My suggestion is therefore to accept starting e.p. moves in the solution when entered by the contributor of the problem/solution - just like castling moves which aren't always legal either.

One need not adapt the solver module to accomodate starting e.p. moves. The contributor is simply instructed not to invoke the solver module by not specifying the maximum number of 3 moves which triggers the solver.

But the applet does allow starting with an e.p.-move - even if the composer did not mean that Smile.

It only takes a bit of knowhow from the solver. Once (s)he is convinced that the problem starts with an ep and the pawns are technically in the right position, (s)he needs to right-click the pawn to be ep-captured, select the ep from "local menu" and the wavy pattern around the pawn will appear. Then ep-capture can be performed.

The e.p. interface is not intuitive and has other drawbacks. For one, the starting e.p. move cannot be entered n the navigation tree which renders it practically useless. The solver must be able to verify his solution there.

The correct way for the program is to handle the e.p. move at the start of a solution just as it would during a solution. Thus, it is always considered legal. Unwanted side-effects are controlled by the navigation tree. Any starting e.p. move that does not appear in the navigation tree, is immediately rejected with the "unsolved" message.

This method is intuitive, easy to program and much more powerful than the current handling.
