Lyf How to reach or beat a GHS? (Part 7)

Some more tips

Almost any GHS came from the GHS holder’s several replays of this level.
Step by step. If you are not sure that you solve the level, don’t consider saving moves. If it can be saved by hundreds of moves, it’s prob. useless to consider saving 2 or 4 moves unless the 2/4 moves has no relationship with the hundreds of moves. If you believe moves can be saved, you needn’t consider about shots.

Counting and Going

Sometimes we should count the moves: “which way is better? “, while sometimes we only go twice to test. It’s hard to way when to take which medicine, perhaps needing experience.

Units

I define that 6 moves is a unit because in many levels we should push many blocks, and we usually let our tank move like a knight in chess. The knight go and return—such as our tank takes 6 moves.
If you can find ways to save moves in some units:6-->4 or 6-->2 or even 6-->0, you will be more efficient. Savings are even more, if you can do several similar processes in that level.

Avoid of long trips

Long trips can be avoided or be reduced by some ways.
One is to use mirrors. Levels containing enough mirrors are usually corresponding to surprisingly good GHS. Eg. #0203—GHS is only 34/51.

Even & odd

Imagine a 16*16 field, whose cells are painted black and white one by one, like the chessboard. So, when our tank makes one move, the color under it changes. That is, if we put a flag on a grid which has the same color as your tank’s original position, your moves to the flag must be an even number. On the other hand, If Flag and your tank stand at grids with different colors, you will get a odd number.

Data never tell lies

Newbie like me (when I was young 12 years ago) may got surprised while finding a GHS contains soooooo few moves. However, Data is honest so it is always possible to reach. Be confidence. Further, data are good hint for us.

The relationship and the difference of “strategy” “efficiency” “ability”

Hi all,
Here I will challenge myself to try to write something about how to reach/beat a GHS. Actually I am not as good as a few GHS hunters, with keeping (only) about 70 GHS in lasertank.lvl file nowadays. But since no one wrote about this topic before, I would like to make a start.
In order to describe things better, I have to say something about how I beat some GHS of levels. Then readers may have more chances to re-beat them. I welcome the re-beating but if someone beat one of them after watching my following hint, please send a comment.
