Flits

Flits created by Adri Vermeulen is a strong engine. Flits always thinks about the current board position. You can select one or more games and let them analyse by Flits. Of course you can also play a game against Flits.

Thinking

When you replay a game Flits always analyses the current board position. In the first line of the engine window the move calculated is shown. In the second line the evaluation is displayed. The evaluation is expressed in piece units from the point of view of white. A positive evaluation means Flits thinks white has an advantage. A negative evaluation means Flits thinks black has an advantage.

Waarde

The value of one piece is 1.00. A value of 9.99 or -9.99 indicates Flits has found a winning line. To the right of the evaluation the search depth is displayed. The search depth tells you how many moves deep the search has progressed. The value is in ply or half-moves. The time display indicates how long Flits has spent so far on this individual move. In the section below the search information you see the best continuation Flits has found so far (principal variation).

Variation

You can play through the Flits main line on a small board. You can insert the Flits variation into the game notation. Flits shows you the immediate threat, i.e. what the opponent could do if no defensive move is made. You can lock the analysis engine to a particular position. After that you can move around the game without the engine following. When you unlock the engine Flits follows the current board position again.

Analyse

Flits can analyse one or more games automatically. Choose the number of seconds per move. With a high treshold only grave blunders will be considered. With a low treshhold the number of 'Better is' commentaries and variations will increase. Analysis always starts at the end of the game and goes backwards until the Last move is reached. The 'Better is' variations are added to the game so that you can replay them easily.

Progress

During automatic analysing the layout of the main screen is adjusted. When analysing has finished the program turns back to the normal main screen. The calc time per move can be changed at any time. The estimated time left for all remaining positions is displayed.

Better is

The program adds the Flits comments to the game as variations. These are prefixed with the 'Better is' symbol. At the end of the variation the evaluation and the search depth is displayed. The evaluation is from the point of view of white.

Blitz

You can play a game against Flits. You can also play against Flits starting with the position currently on the board. You can choose between blitz game and long game. With Blitz (Blitz timecontrol) you can select from a number of blitz time controls. You can also use a 'Fischer clock' which gives each side extra time for each move played.

Normal

With normal times (Long timecontrol) you can set longer time controls for 'tournament' games. They usually have number of phases, e.g. two hours for the first 50 moves, one hour for the next 25 moves, and 5 minutes for the rest of the game. You can adjust each of the time allocations or number of moves per phase. Or you can select one of the common predefined levels. When you leave the second and third time control blank they are not used. The first time control is always used.

Play

After setting the time controls the game starts. If the engine window is hidden it becomes visible. If the clock window is hidden it becomes visible. The clocks are not ticking. They start ticking when the first move is played. Flits takes the side not to move first. You get the side to move first. The program waits for you do play the first move. After you play the first move the clock starts ticking. Swapping the players is possible if no moves are played so Flits takes the other side and plays the first move.
