Strange ideas about play against too strong opponent
Except from resigning immediately against an opponent which is much too strong I thought maybe it is a good idea to give a much lower value to the rooks. For the rooks only get active after move twenty and at that time your position is already hopeless. Another idea is not to check for promotions of your pawns.

And maybe increase the value for pawns still in its initial rank. Your opponent needs more moves if you keep your army far from him/sheHenk wrote:Except from resigning immediately against an opponent which is much too strong I thought maybe it is a good idea to give a much lower value to the rooks.

Re: Strange ideas about play against too strong opponent
Other ideas are of course to increase the weight of your own king safety and double or triple thinking time for first twenty moves.

Re: Strange ideas about play against too strong opponent
Changing value of my rooks does not seem to work. In this game blacks rook values are set 0.25 times their normal value. So their values are a bit more than a pawn.

Try to give a bonus for pieces near to their king and avoid pawn pushes, as said before. maybe you can reach move 20.

Re: Strange ideas about play against too strong opponent
Setting rook value to zero does better for in this game white exchanges its bishop for a worthless rook.

Re: Strange ideas about play against too strong opponent
Yes a record 44 moves. Skipper just did not count white's pawns and blacks rooks. Shame on Stockfish. ELO difference at least 1200 points.
