Why wasn't this a draw via threefold repetition?

assuming this is whites move white k2a8 black k2f7 check pawn to b8 queen to b8 king to b8 free now still in that same start with the king 2 a 8 if the bishop takes pawn then white gets a queen if the rook goes up then white gets a queen so this is the most logical move to sac the queen that way it is checkmate which is why this isnt 3 fold because checkmate is still a threat

I have no idea what you are trying to describe but no draws require anything like what you just described. You can draw by these means:

• Stalemate - where a person is unable to make a legal move and is NOT in check
• Agreement - both players agree to draw the game in any position
• 3 fold repetition - if a position is appears 3 times in a game either player can claim a draw when the position is on the board (if they play on then the draw claim is invalid unless it appears again during play)
• 50 move rule - if after 50 moves no captures or pawn moves have been made then the game can be declared a draw by either player (although if neither player claims the draw and a pawn move or capture is made when playing on then the draw claim is invalid unless another 50 moves without pawn moves or captures occur)
• Insufficient material - neither side has enough material to checkmate the enemy king (eg. K + B vs K)

The rules are not as complex and confusing as they are in your mind, ramses9721. Please, if anyone asks you to explain the rules of chess, don't do it

The FAQ page should contain links to threads like this one

ur an idiot i just described that get glasses there is no draw if checkmate is still a threat 3 fold is only used when the king has no other pieces to move and isnt forced to move into check or move out of check it resets each time the king is put in check

also there are points of attack which the king can defend

O_o (I don't know what to say)

u cant have a draw in a real life game if there are other pieces to attack with look up the damn rule book not talking about 2 people declaring skill draw i mean actual inforced draw where u cant move ur damn king it can only be inforced by repitive movement when noth other pieces can move but the king

.

Yes you can. Read my post (post 22). Stalemate, the 50 move rule and 3 fold repetition can all be reached even with other pieces on the board.

Huh??? Threefold repetition has nothing to do with whether either side can force mate, move his king, put the other player in check, or any of those other situations.  It simply means either player can claim a draw if the exact same position occurs on the board three times.  And there is no "reset".

In TitanCG's post above, White could claim a draw after Black's move 5.

Beginner: Is this a draw?

Ramses: No, not until you win the set by two games.

Beginner: What? I'm not playing tennis, I'm playing chess.

Ramses: You still have to score a goal.

Beginner: What?

In addition, there is perpetual check, where one player can earn a draw by being able to put the other player in check over and over again (a variation on threefold repetition).  I've actually been fortunate enough to convert a couple of lost games to draws because my opponent made an error allowing me to administer perpetual check.

Perpetual check is covered in binblaster's list of draws, since it always results in either draw by agreement, draw by repitition or draw by 50 move rule.
