Under promotions for pawns during a match game
Has anyone used or had interesting stories of under promotion which of course I mean to a Knight, and did it help you in the game.. was it a mistake?
I recently had a correspondance game where my pawn was sitting on the 7th rank for a while and I could have made it into a knight to give check. I greedily held on to it hoping for a Queen and ended up losing the game. I also lost the opportunity to make it into a knight because my opponant defended the check idea that had come up earlyer. Kind of regret not just making it a Knight for the sheer fun of it (game against a mate) and, as I said, it may well have saved the game.
Unlikely it will come up again for a while.

A game between the late Tony Miles and Michael Adams from 1993 comes to mind.Kevin O'Rourke wrote:Has anyone used or had interesting stories of under promotion which of course I mean to a Knight
They reached this position with White to move.
The Shredder tablebase tells me that Ka4 also draws, but Adams played the amusing and necessary b8=N. That's dramatic as b8=Q allows mate in one.

Re: Under promotions for pawns during a match game
These are famous games but what about club or even friendly games. Also like I said, were there any interesting options/threats to do it that influenced the game? Would be great to take someone by surprise when a horsey appears with a devastating fork or check.

Re: Under promotions for pawns during a match game
The closest example in my games was this missed opportunity. I played 41...Rxd2 and won easily enough, but there was a mate in three available.

Re: Under promotions for pawns during a match game
I had a recent game where underpromotion didn't appear on the board, but was a major threat.
Black has just played ...Rg8 threatening mate - White to play.

Jesper Nørgaard - Abel Davalos Club Mercenarios 2003
White to move and win - actually it seems to be forced that underpromotion is the only winning theme in this position.
The page http://www.chesschat.org/showthread.php ... -checkmate actually shows 5 underpromotions from my games alone. There is an underpromotion from Kevin Bonham. Come to think of it, in my youth I had a sixth underpromotion to a bishop, creating the pair of bishops, which I duly went on to checkmate with. Sort of a protest that he didn't resign. Of course you shouldn't do that, as that only encourages the opponent to play on.

Re: Under promotions for pawns during a match game
When playing online I have done an under promtion to a rook just to give checkmate along a rank or file.

Re: Under promotions for pawns during a match game
I am still trying to solve the mate in 4 from Jack's game...
I haven't solved Matt's poser either (does it start with Qh6+?).
I did get Jesper's one (a good example).

Re: Under promotions for pawns during a match game
I suppose everyone knows the trap in the Albin that leads to a position with three Knights.
4.e3 is a little inaccurate as you have to accept the position with pawns on e5 and e3 with 6. fxe3

Re: Under promotions for pawns during a match game
Who came up with the term 'underpromotion'? In, albeit rare, circumstances where its advantageous to 'underpromote' it's something of a misnomer to call it that as the piece promoted to, for example a knight may have more value than a queen in the position at hand. If promoting to a knight can deliver mate, for example, shouldn't we call it overpromotion rather than rely on a singular generic term.

Re: Under promotions for pawns during a match game
Very nice puzzle! It does start with Qh6+, and I was stuck for a while on how to meet the Rg6 defence, but have got it now (EDIT: though some of the lines end in draws? Is it a win for White or a draw?).Christopher Kreuzer wrote:I haven't solved Matt's poser either (does it start with Qh6+?).

Re: Under promotions for pawns during a match game
Amusing story - back in the 1970s I was playing as a 12 year-old in a section of the Kent Championship, when games were arranged between individuals, and often played at one player's home. My father gave me a lift to Chatham one evening to play a chap who didn't know this trap; he played Rxg1 and resigned after Bg4+, total game time about 5 minutes. Unfortunately my father was on his way home to Petts Wood, expecting to pick me up several hours later, only to arrive home to a call instructing him to turn round and drive another 45 minutes back to Chatham - no mobile phones back then. A slightly awkward evening for all.Roger de Coverly wrote:I suppose everyone knows the trap in the Albin that leads to a position with three Knights.
I saw Jack's mate in 4 immediately. Was trying to create a mate in 3 but Nd4 fails.
