Can you draw against any of the top 4 engines

Post by Chessqueen »

The Engine will have the first move with Black and you are playing with White, Please do NOT cheat by using your engines to Analyze the position, but instead try to use your ending technique or knowledge against the engine playing with the Black pawns :roll:

Hello:

The position was familiar to me. This theme was already posted in June:

See if you have the Chess Talent, don,t use an engine

The only difference is that the two kings have been added now.

Regards from Spain.

It also apply if you position the White Queen on a1, but this time Black will alway select the ....b2 as the first best move try to get a draw playing with white against any of the top 20 engines :wink:

But if you set the White Queen on c1 you will be able to win no matter if you select the best engine , since it will find ----d2! as the best move for Black,but this move will NOT save the Black side from getting mated :roll:

There are different ways of Drawing, Since the Queen has such a long range and possibilities of moving in different directions, for instance
