Chapter IThe River1 / 8
Control the Midfield
The two river rows in the centre are the board's hinge. Pieces that cross the river gain new powers — Navy slides sideways, Guerrillas enter ambush range. Contesting these rows forces your opponent into awkward retreats.
Tip: Place a General (Tướng) aimed at the river early. It slides up to 3 squares and threatens the crossing before your opponent can fortify.
How AI Predicts Your Next Move
Markov Chains & Chess Intelligence
Every time you move a piece, the engine running this board updates a probability model — one that treats the entire chess game as a Markov process. Here's how it works.
What is a Markov Chain?
A Markov chain is a mathematical system that hops between states with fixed probabilities — where the next state depends only on the current state, not on how you got there. In chess terms: the legal moves available right now tell you everything you need to know.
The Markov property in chess: Given the current board position, the probability of each next move does not depend on the sequence of moves that produced this position. Only the state — the piece layout — matters.
Building the Transition Matrix
The AI builds a transition matrixP[s → s'] where each entry is the probability of moving from board state s to state s'. This matrix is never fully precomputed — instead the engine approximates it through:
Move frequency tables — positions from past games, weighted by player style and opening choice.
Alpha-beta search — minimax tree pruning that evaluates future states and selects transitions with the highest expected value.
Heuristic priors — terrain bonuses (river, forest, mountain) shift probability mass toward moves that exploit the map.
Predicting Opponent Moves
At each turn the engine maintains a belief distributionover the opponent's likely next moves. It is updated via Bayes' rule every time the opponent acts:
P(move | position) ∝ P(position | move) × P(move)
The prior P(move)starts uniform — all legal moves equally likely — and sharpens as the game progresses. After observing an opponent's preferred river crossings or ambush setups, the AI assigns higher probability mass to matching future moves.
Terrain as a State Modifier
Vietnam Chess's terrain system makes this Markov model richer than a standard chess engine. Terrain tiles create non-uniform edge weights in the state graph:
TerrainEffect on transition probability
Forest↑ weight for Du Kích / Nông Dân (ambush threat zones)
River↑ weight for Thủy Quân crossing; ×0 for Voi
Mountain↑ weight for Chỉ Huy leap; blocks Cannon line-of-sight
From Theory to the Engine
The engine powering this board runs a depth-6 alpha-beta search with terrain-aware evaluation. Each leaf node is scored with a value function that approximates the stationary distribution of the Markov game — the position where neither player can improve their expected outcome unilaterally. That equilibrium is a Nash equilibrium, and the engine's goal is to play toward it.
“The best chess engines don't just see further — they assign probabilities to where you wantto go, and play to narrow your options until only bad moves remain.”
The Markov framing also explains why openings matter: early moves collapse the state space rapidly. Each exchange eliminates branches, making the transition matrix sparser and the AI's predictions sharper with every turn.

Power Output
P = η × V × I
Where: η = efficiency, V = voltage, I = current
Battery Range
R = (E × η) / (P × v)
Where: E = energy, η = efficiency, P = power, v = velocity
Thrust Efficiency
ηprop = Tactual / Tideal
Where: T = thrust, η = propulsive efficiency

E = P × t / η
Where: E = energy, P = power, t = time, η = efficiency
Motor Torque
τ = (P × 60) / (2π × RPM)
Where: τ = torque, P = power, RPM = revolutions per minute
