Graphic for sacrificing pawns and pieces:
Sometimes, if you make your opponent use a lot of time, it's worth it to sacrifice some pieces. Here is a graph:
First 10 seconds: Pawn=10 seconds Minor Piece: 20 seconds Rook: 35 seconds: Queen: 45 seconds
40 secs--49 secs Pawn: 5 seconds: Minor Piece: 15 seconds Rook: 30 seconds Queen: 40 seconds;
30--39 secs Pawn: 2 seconds; Minor Piece: 7 seconds; Rook: 15 seconds Queen: 30 seconds
20--29 secs Pawn: 1 seconds; Minor Piece: 3 seconds; Rook: 8 seconds Queen: 15 seconds
10--19 secs Pawn: 1 seconds; Minor piece: 3 seconds; Rook: 6 seconds; Queen: 12 seconds
1--9 secs Pawn: 1 secs; Minor piece: 1 seconds; Rook: 4 seconds; Queen: 5 seconds;
Final Five Pawn: half a second; Minor piece: 1 seconds; Rook: 2 seconds; Queen: 3 seconds.
