Chess Endgame: Using Underpromotion

This seemingly ordinary Rook + 2 Pawns vs. Rook ending provides us the opportunity to discuss examples of underpromotion in the ending, and endgame concepts in general.

This video is a little more geared towards beginners than my other videos.

just a7 is so much simpler Kb7 rc7, etc

[GreenCastleBlock]

@Chessczar simpler as in fewer moves, yes. That's not the point of this video. Read the description please.

I would play a shorter variation starting with: 1 a7,but in move 4 b7+instead I'd play 4 Rc8 and next move mate is unavoidable 5 b7++.Here is the variation: 1 a7,Kb7 / 2 Rc7+,Ka8 / 3 Ka6,Rb8 / 4 Rc8,Rxc8(forced move) 5 b7++ mate!!!

[GreenCastleBlock]

@Evarishi 1.a7 is faster.

[xie924]

In the beginning. a7 or b7 can also lead to mate don't you think?

[GreenCastleBlock]

1.Rc8+ is the most interesting win, but 1.a7 and 1.b7+ both win as well, with 1.a7 being the shortest path to checkmate.

Great vid

Keep up the chess vids

[jackfruit22]

right ongyi, simple and accurate. No complications!

[audiofiel]

end game can be quite elegant if you do it right

[plutonian32]

It may be the slowest, but Bishoping the a pawn after knighting the b pawn is definitely the sexiest way to win.

[ManhattanProject9]

Actually i stand corrected. a7 is faster. If you do pb7+ then Fritz puts his king at a7. If you move your rook to c8 then blacks rook refuses to exchange instead he starts checking. You end up winning either way. but a7 is faster.

[ManhattanProject9]

Correct me if i'm wrong but isn't pb7+ even faster? King can only make two moves. If ka7, then Rc8. If rook takes then queen promotion.

If Kb8 then Kb6. Then he MUST move his rook, any move he makes pa7 checkmate.

I like pb7+ best.

[CaraBrimleyRules]

It is mate. Check it out ;-)
