Game #10 Analysis:

Lessons from this game:
> Be careful when taking advice. Some apples are poisoned.
> Gain more knowledge and experience.
> Humans make mistakes, it's just the way it is.
> Study your black openings.

Now I'll give you the strategy descriptions. If you couldn't catch my returning article, note that I have made a few modifications to the Super Eval with a few added techniques such as position categorization and the rule of ratios.

Super Eval

Super Eval is a system in which you take in the situational conditions, process them to make a verbal evaluation, and choose the move that best suits your evaluation. Let's go through the steps one by one.

Situational Conditions

Situational Conditions in a tournament game can be divided into 3 main categories. They are:
1. Board Situation - Comparison of No. of Hanging pieces, King Safety, Alignments, Material, Controlled Squares, Mobility, and Pawn Structure
2. Clock Situation - Comparison of Time available per move
3. Psychological Situation - Comparison of Tournament pressure, Spectator pressure, Rating anxiety
Evaluating the situational conditions correctly requires a lot of experience. This is more of an artistic approach to chess rather than a theoretical approach. For this blog series, I will only be explaining how to cope with the board situation.

Dynamic or Static?

This decision is not that difficult to make. The theory is, that if there are tactical weaknesses in the position (Hanging pieces, King Safety, Alignments) then the position is dynamic. If the position doesn't have any tactical weaknesses, then the position is static. If the moves that exploit the tactical weaknesses in a dynamic position do not work, then it's also a static position.
Now that we've decided between a dynamic and static position, let's look at each one of them.

Dynamic

If the position is dynamic, you have to switch to the MCTS. The description of the MCTS can be found at the bottom of the article. But if you realize that the moves exploiting the tactical weaknesses do not work (i.e. do not give you a better position after using the MCTS), then you have to consider it to be a static position.

Static

If the position is static, then you have to make a plan related to your verbal evaluation. More than anything else, this requires knowledge and experience. I won't be discussing how to make a plan in this article because there are plenty of other books and articles that teach you how to make a plan. Once you do have a plan, you have to get a list of candidate moves that could help you accomplish your plan. After you get a list of the moves, you have to select one of them. This is where the Rule of Ratios comes in.

Rule of Ratios

What this means is that to select a move from your list of candidate moves, you evaluate the Effect: Drawback ratio of the above moves. And you play the moves that have the highest effect-to-drawback ratio (with the effect side being higher). To evaluate the effect and the drawback of a move, you have to evaluate the Attack: Defence ratio of your effect or drawback. For drawback, this means how much attack from the opponent is there compared to your defense of the drawback. For effect, this means how good is your attack/effect compared to the opponent's defense against the square or piece you are having the attack/effect against. Again, this method is artistic. It's not entirely theoretical. So if you are going to use this method, perfecting it with knowledge and experience is your duty. Now I'll give you the method you have to use in dynamic positions.

Monte Carlo Tree Search

> First, we take a list of candidate moves and see which moves are most preferred by our intuition.
> Then we make a play-out (a.k.a roll-out) by applying the same principle from our opponent's side and mark the evaluation when a static position is reached.
> Then we take the average of the so-found leaf positions to assign a value to the calculated candidate move.
> Then we repeat the process for all the candidate moves and compare the move values to come to a final conclusion.

When using this method, it's important to broaden your list of candidate moves rather than going deeply into one line. Going deeply into one line can make you miss simple moves available for your opponent that would give them the advantage. In doing so, you also run the risk of missing moves that would have simply granted you a better position. This was well proven in the game Glance at everything. In situations where you don't have enough time to glance at everything, just glancing at the intuitional moves is acceptable.

This is how I am going to go forward. Beating Stockfish would sure be a difficult task, especially after switching to chessui.com. But I believe that it's not impossible. Playing these games and writing articles on them is exhausting. But I have improved a lot through this series. So I guess it's worth it. I hope this series is instructive to all the readers and don't forget to share your thoughts in the forum!
