Yep, after Be3 ...Ng4 is a very strong move. If the bishop goes to d2 (we saw on f2 you take and ...Bc5) then ...Bc5+, Kh1 Nf2+ wins the exchange as the K&Q are forked.

One thing I don't like about this particular puzzle is that there are probably 100 or so games like this as it is early in the opening and I would have played 1...Ngf6 without any thought, but with this program you need to wait 5 minutes. I understand the concept and I tell students to take stock on any new position they encounter when I give them a study, to count and compare the pieces, determine where the action is needed, select candidate moves etc. The five minutes is well spent on this type of thing. However, in this particular position there are many moves which I am sure would score decently even if you they vary from what you played here. I understand the concept, I just wish there was a 'Get On With It!' button - or "Click here if you are an impatient person".

This may be nitpicking or whining but the point to me is that if I am spending 10 minutes on opening moves I am taking too much time. There are a lot of lines where I can reach move 20 or more in a couple minutes, leaving me more time for more critical decisions. In this example, ...Ngf6 was a no-brainer. Castling was a no-brainer, so that would at some point bring me to a position where I _do_ want to settle down for a deep think, and this is where I would like to start the quiz.

Instead of the "Get On With It!"" button, maybe they can set up the initial position of the quiz but allow the user to proceed with moving right away (it may be an opening you know well) and then, when you reach your limit you can press a "Quiz Me" button and start your test from that point.

An improvement for the developers may be to make it possible to click the 'from' square and then the 'to' square instead of having to type in the move. The way they have done it is very practical, but developers should strive to make everything easy on the end user, and clicking the squares would be an improvement IMO.

That being said, I am liking what I see in this program. Perhaps you should send them a link to these threads so they can read the viewers comments and they might see something they'd like to incorporate in the future. This program seems innovative and promising, I would just say there are a few tweaks that need to be done. I am impressed, but I think with some more work they could be at the top of the market.

Chess Position Trainer is an example of taking an idea to the fullest, it is a different type of program that was basically the brain-child of one man. He put out several free versions until he was sure that he had tweaked it enough to be the best it could be. That release of CPT 4 came around the turn of this year. It is a great program, very good indeed, and is in my opinion a must for people who want to improve and refine their openings. Even as of today he still keeps things updated but the basic format is unchanged from the original CPT 4 release. He did all this based on feedback from the chess playing community, not just a select few friends/colleagues who happen to play chess. The developers at Lucas Chess have the same possibility.

Thanks for bringing this program to my attention.

You can set the minimum amount of time to anything you'd like. I have it set to 5 minutes to force myself to do this, no matter the position, because that is one thing I need the most work on. You could set it to like 1 second or maybe even 0 if you wanted.

Oh, also you can do this. I usually do, but when I made an error I went back and typed it manually. You can certainly click the from and to squares to enter the moves.
