haha threat-threat-threat mate

[OneWeirdDude]

What is "suki"? Wiktionary and Wikipedia were no help, except to confirm that the characters are katakana: スキ。 That also makes me curious as to why they are not in hiragana instead, since the term is Japanese - isn't it?

threat threat threat threat threat threat threat threat threat threat threat threat threat threat threat threat threat threat threat threat threat threat threat threat threat threat threat threat threat threat threat threat threat threat threat threat threat threat threat threat threat threat threat threat threat threat threat threat threat threat threat threat threat threat threat threat threat mate

[simonguoxm]

This one is a little bit like liberty counting in Weiqi/Go.

And there is a weiqi/go proverb... Sacrifice to get sente.

[vinniram]

also, how come you didn't teach us the "ze" castle in your videos on castles. if it's unmateable, shouldn't we use "ze" all the time, rather than yagura, or anaguma or mino or whatever else?

[HIDETCHI]

No, no, "ze" is not a caslte. "ze" means a situation where your king won't be in a forced mate starting from the very next move, no matter how many pieces your opponent has.

So, any kind of castle can experience "ze" on certain occasions.

[vinniram]

when you say "forced" mate - aren't all mates forced?

[HIDETCHI]

Let's suppose you can mate your opponent's king with consecutive checks.

Technically, only the position after your final check should be called a "checkmate". But usually, we tend to say "this king is in a mate" even before your first check. Strictly speaking, this should be discriminated from "checkmate", and termed as "forced mate", since the king will be forced by your consecutive checks to be in a "checkmate" at last.

[OneWeirdDude]

@vinniram I guess Hidetchi already answered this. But to give you my answer, no. For lack of a better example, in chess, you cannot make the lone king with just yours and two knights. But if he blunders, he can be mated. You did not force this, and he could have avoided it.

[vinniram]

how come at 6:42 sente is impossible to mate? If the opponent has all the pieces in hand, can't he simply draw out the gold using pawn drops, then draw out the king and mate?

[HIDETCHI]

Let me remind you again that "cannot mate" means that the king cannot be forced into a checkmate with consecutive checks. (i.e. forced mate)

Pawn drop on the gold is not a check. White's any move that is not a check is nonsense, because white's king at 6:42 is in a threatmate, so black can ignore the pawn drop on the gold and checkmate white's king.

[vinniram]

so with speed calculation, you don't count your own moves when the opponent reacts them. is that correct?

[HIDETCHI]

Exactly!!

You don't have to count that move, because if the opponent was to react to that, then your king receives only ZERO move of attacking by white.

[HIDETCHI]

I mean, by your opponent.

[Exkaliki10]

HOw do we know exactly when our King or the oppponents King is in a Z?

[MXdetty]

i still dont understand brinkmate?? can sombody explain it to me again?

[HIDETCHI]

Brinkmate is a kind of threatmate that cannot be removed with any move or drop.

[manitopark]

Let's put this way. "Locked in"  No matter what moves opponenet makes after "locked in", it 'll be checkmate.

Does this heip you understand brinkmate?

[MajongEMF]

Thank you for all this video series, and keep going!

[Dparrey]

Im nowhere near up to this yet but it was very interesting to just watch and try to understand a thought process of the game.

[Hafesie]

HAHAHA Zed so funny.

You need a whole army to do the knight zed mate its basically a zed anyway
