Expressions from my writing "Now or never -- a fish that tries to fly"

Hi Everyone!
In case you are reading my blog entry "Now or never -- a fish that tries to fly", you might need to know the following sport -- mainly chess ;) -- expressions:

• to tie for (a place): to share the place, having the same points. 'holtversenyben végezni'
• to throw in the towel (or spounge): to admit defeat, stop fighting. 'bedobja a törülközőt, feladja a küzdelmet'
  
• draw: the result when nobody wins, the point is shared: 0.5-0.5. 'döntetlen'

And the explanation of the chess-connected but known words:

• opening-middlegame-endgame: the 3 parts of a chess game
• handshaking: chessplayers shake hands at the beginning and at the end of the game
