Nf6xe4 is something you will not become happy with. Why?

The answer is in one of my above posts

Move I posted by accident. I'm still thinking about it.

My little sister must have hit the enter key when I left for work. She loves buttons

It was supposed to be notes for my thoguht process.

The black queen and the white King stand in one line. Pieces on that line eventually can be removed, creating threats that way.

the white queen stands unguarded, and on the same diagonal like the black queen. Black can increase his pressure on that diagonal and again create threats.

both situations invite for being exploited through motives mentioned in rule #16 "Covered attacks". that motive should drive you.

I am only a beginner\intermediate chess player, and this is a great thread. I am learning a lot.

I do have a question. Is there a defined point where the opening becomes mid-game and then also to end-game or are these gray areas?

In the game above for black, if I may, I like Bf8-e7. d5xe4 can soon be played. White must be wary of moving it's D pawn opening that file.
It adds pressure on White's queen (the knight at f6 can now move) and allows black to castle soon, getting a rook in play.

White would have little choice but to move his queen to a safer spot and lose time.

Although books on openings sooner or later come to an end in describing a variation, nevertheless I would consider the border between different phases of the game being fluent. Many openings are - in theory - so long that they reach far into midgame. Preparation to gain a promising endgame begins in midgame - sometimes even the opening's idea already is about favourable constellations (pawn phalanxes or majorities on one wing) in the endgame.

Profi players study all this a lot, so even if they do not calculate the variation tree let's say 20 moves in advance , they nevertheless eventually already look into the mid and endgame when choosing their opening by considering the basic idea and typical position types resulting from it.

Profi players also calculate it differently than we usual mortals do. They tend to recognise constellation patterns of figures, not single figures themselves. Simple example, where you see and calculate with pawn f2, g2, h2, Rook f1 and King g1, they take the position as a whole and use that description of a short casteling as the basic unit to calculate with. The same they do fopr example with pawn phalanxes and typical positional patterns resulting from a given opening. Pattern recognition is very important in professional chess, and you cannot make it to that level of playing strength without having accumulated those many thousands of hours of playing that result in your mind seeing patterns instead of pieces and single moves. It is illusory to assume you could make it to that level by calculation alone, like you also do not become a good pianist by playing technique alone, but missing the heart to interpret the music and wgive it soul and emotion. Sould and emotion in chess is pattern recognition, so to speak.

Obviously it is also important in chess programming. Pattern recognition, and mathematical criterions by which to judge a given position or pattern are the bread and butter of it.

Your move is very good, btw. It develoeps a figure. It brings Black closer to casteling. It poses a covered thread to the queen. It supports further attack in the centre. It is more than White can handle with just two hands.

Could you give Lance a full possible variation? Ypou already outlined a plan: to play de4: any time soon. What replies are possible for White, and what threads? Which one do you expect? Could you counter White's attempt to hinder your plan?

6........Bf8-e7
7. Qg3 ..attacking 2 undefended pawns at f7 and e5
7........ /O-O
8 Qxe5 d5xe4
9 Nc3xe4 bf5? or Qxe4 Rf8-e8

At this point I feel I've lost some momentum. I expect white to want to develop his bishop at c1 so he can move his king off the e or d files.

I have no chessboard set up and I failed to get arena to work so the board is difficult for me to "see" after this many moves.
Does arena require a chess engine to just set up 2 human players and make moves?

Hmmmm.....

After much consideration I have decided that I like that move
In this way, black can further the goal of eliminating white's bastion in the center, and the white queen remains at bay. White's knight at g1 vexxes me, however. Should I castle and move my f6 knight to press an attack on the center, he is in a position to support an attack by the white queen on h7. Potentially only 3 moves away in fact, after white moves his queen to h5 to evade my bishop. Admittedly a vague fear, but my main concern is that such a ploy by white will interfere with black's advance and possibly reverse the situation. As such, I'm not liking the idea of castling at the moment, but have not ruled it out.

Other than that, good show Rick! Thanks to the suggestions of people like you (and sky, of course) I get a little closer each day to my ultimate goal of being able to start the thread : UnderseaLcpl vs. Skybird.

Bf8-e7, then?
