THE ANSWER HERE IS EASY! THESE DGT Pi CHESS CLOCKS ARE LOADED WITH NUMEROUS, STRONG CHESS ENGINES; MANY ENGINES CAN BE SET TO LOWER LEVELS TO EVEN OUT THE PLAYING FIELD! I HAVE HAD TROUBLE CONNECTING LAPTOP PROGRAMS TO SEVERAL E-BOARDS; THE PROBLEM WAS ALWAYS THE SAME - EVENTUALLY DURING A GAME, THE LAPTOP SCREEN WOULD MALFUNCTION. THESE CLOCKS ELIMINATE THAT PROBLEM. THERE ARE A NUMBER OF USEFUL FUNCTIONS; YOU CAN SET AT LEAST 20 DIFFERENT TIME CONTROLS, FROM LONG GAMES WITH "FISCHER" INCREMENTS, BLITZ GAMES, OR G15, 30, 60, OR 90, ETC; THE POSSIBILITIES ARE SUITABLE FOR ANY TIME CONTROL. YOU CAN CHOOSE FROM A VARIETY OF OPENING BOOKS THAT DESCRIBE THE STYLE OF PLAY, FROM OPEN GAMES TO SEMI-OPEN GAMES, TO CLOSED GAMES AND ANYTHING IN BETWEEN. THIS FEATURE IS GREAT FOR PRACTICING SPECIFIC OPENINGS, WHICH IS MY PRIMARY USE. AND IT HAS A DOUBLE USE AS A REGULAR TOURNAMENT CLOCK THAT IS EASY TO SET FOR TIME FUNCTIONS. IF YOU WANT AN ALL PURPOSE CLOCK, LOOK NO FURTHER - THIS IS YOUR ANSWER. JUST CONNECT THE CABLES AND USE IT ANY WAY YOU WANT WITH AN E-BOARD, WITH OR WITHOUT BLUETOOTH. A GREAT VALUE FOR THE PRICE, WITH A CHESS HOUSE, USA-BASED STAFF THAT PROVIDES AN ANSWER FOR ANY QUESTION YOU HAVE. NO RESERVATIONS ON THIS ONE. I BOUGHT TWO! LEN

Very interesting way to play. Extremely easy to change configurations using extra queens. But,
Lag was disappointing esp during blitz. Voice announcement never works for faster time controls.(starts with voice then automatically stops later )..and in almost all cases computer lost on time, esp in 5-5 or 3-2 which is classical blitz controls...I had tried stockfish higher levels ...but even with good position it always lost on time...but for classical.time controls ..it's great..another negative is the update option
Updating dgt pi is very complex and I am surprised ,on that prize why can't they give wifi with auto update? Given the cost factor, there are lot of scope for improvement.

I first learned to play chess in 1972 at age 10. I am now starting to “learn” to play chess. The Pi and DGT board allow me to have a real game at anytime on a real board. While I am yet to win even a single game . I am studying and can see small improvements. I will recommend this system . From a beginners standpoint it is a lot of fun.

I just hope this one lasts a long time. The first one last about 6 months before it stopped working. So far so good for the new one.

So i know there are many other chess computer options out there, but this one also is a full featured DGT3000. Which is still considered a great clock by many! I have the vtek 300 as well but i see this clock in so many tournaments. Another cool thing is, if you are a causal home player, you can put this in observation mode and the clock will be triggered by moving pieces. So if you and your buddy wants a clock but not having to press... then this will do it! It will also give hints so if you are coaching someone, you can use the hints as a teaching aid. Combine this with the new DGT smartboard and you are in business! So instead of buying some “gadget” with blinking lights and small size, you can have a full tournament size board and clock that can be used as computer or a no powered board and still look fancy... Just get over the looks of DGT plastic pieces and realize that someone would love to have even your $14 club set...
