Another win condition idea

If one player is up 15 points or more in material and not able to mate within 10 moves, the other player wins.

wow that's radical

imagine if a player was down a rook and lost a pawn

decides to trade queen and the moment his queen was captured, he's down 15 points, and the other player cannot mate in 10 moves, does he win?

He's still down a rook and is about to be only down 6 points(though still enough for win)

Sacrificing a queen and rook to get 2 unstoppable connected past pawns that will both promote

This is a useless idea since anyone would easily be able to convert this into a win.

I should have put it more precisely.

If player A has a material advantage of 15 or more points during 10 consecutive moves, and is not able to mate within this same series of moves, player B wins.

So in your scenario there's no win.

I got the idea when I was playing a 900- who wouldn't resign. I was way more than 15 points up and annoyed that I had no time to find a quick mate.

I wonder if positions can be found where one side has 15 or more points advantage, and a strong engine can't find a mate in 10 or less.

And if these positions do exist but are hard to find, there actually might be some fun in this idea.

I chose this position somewhat randomly and yes, there is a mate in 10 when I ask my engine.

Imagine this happens.

White is up by 15.0 points in material balance, but will take quite some time to extricate the rook out.

Or this.

Can White win in 10 moves?

I had rephrased it to:

"If player A has a material advantage of 15 or more points during 10 consecutive moves, and is not able to mate within this same series of moves, player B wins."

If Black doesn't want to capture any white peace then white can just take all pawns. If Black does take a substantial piece then white the material difference becomes less than 15 points and that will give White sufficient time.
