his rating tells me he might really struggle with this haha which is why im helping☺
Can someone explain this endgame? I suck at chess

But basically the idea of the endgame:
Whoever gets their pawns to the end win, because they get a queen and can pick off all the other pawns.
In this position, white has more pawns on the kingside - this lets him create a pawn that can queen (since if it traded for all the other pawns, there would be one left). On the queenside, black has a majority, but there's a doubled pawn in the majority.
That means that it may be impossible for black to create a passed pawn, and that's indeed true, as long as white never takes any of the black queenside pawns, unless recapturing.

@cherub_enjel Yes I realised that's a perfectly possible (and indeed forgivable way to lose once) for a relative beginner, but again and again for an hour? The mind boggles.

impossible...there is no way he queens before you
i keep back spacing moves and its impossible to win, ill copy and paste what im doing

And you're correct - it's not chess notation.
Literally the person writing the script was too lazy to write "bxc3", so they wrote "bc" instead for shorthand, which is actually quite common.They assumed the people taking the lesson would understand, which now you do.

well i play custom positions on my phone, i dont see that option on my PC, which is what im using for this forum...

Hopefully you understand the position now - and I'm sure if you read the chess mentor lesson carefully, they will mention how the plan for white is to force a passed pawn on the kingside, then abandon it as a decoy for the black king, and then go to the queenside and capture all the black pawns, and have 2 white passed pawns, and get a queen.

so chess.com doesn't allow custom positions? but the phone app does?

Click on ''set up position'', then click on the trashcan to clear the board and set up whatever position you want.
thanks

but on my phone the computer will play in a custom position. here i can only play by myself
If you're losing that as white again and again for an hour, that's quite a remarkable achievment.
Either this is a troll thread, or the OP is always taking and undoubling black's pawns on his first move, and just not realizing it.
