Advanced Ship Placement Strategies

Why Placement Matters

Many beginners assume ship placement is just luck - put ships anywhere and hope the opponent searches elsewhere. This couldn't be further from the truth. Against skilled opponents or higher-difficulty AI, poor placement can cost you the game even if you search efficiently.

Good placement doesn't prevent your ships from being found eventually - that's mathematically impossible against optimal search. Instead, good placement DELAYS discovery, buying you extra turns to locate enemy ships first. In close games, those extra 3-5 turns make the difference between victory and defeat.

Fundamental Placement Principles

The Spreading Doctrine

The single most important placement principle: spread your ships across maximum board area. Ideally, position ships in different quadrants so discovering one ship provides zero information about others.

When ships cluster together, opponents who find one ship can efficiently search nearby areas, potentially discovering multiple vessels from one successful region. Spreading forces opponents to search the entire board, maximizing the shots required.

Orientation Variation

Never place all ships with the same orientation. Mix horizontal and vertical placements roughly equally (2-3 of each). Uniform orientation creates searchable patterns - if an opponent notices all your ships run horizontally, they can optimize their search pattern accordingly.

Advanced technique: Place larger ships (Carrier, Battleship) in one orientation and smaller ships (Destroyer, Submarine) in the perpendicular orientation. This creates different signatures for different ship types, complicating opponent analysis.

The Gap Strategy

Maintain at least one empty square between ships whenever possible. Adjacent ships create "information clustering" - when an opponent hits one ship, adjacent squares become extremely high probability, potentially revealing multiple vessels.

Exception: Against Ensign difficulty (random firing), gaps matter less since the AI doesn't exploit information clustering. Prioritize spreading over gaps when space is tight.

Positional Theory

Center vs. Edge Placement

The eternal debate: should ships occupy central squares or edge positions?

Edge Arguments: Ships along edges can only be approached from 3 directions (or 2 for corners), theoretically making them harder to explore fully. Edge squares also counter the common strategy of prioritizing center squares in searches.

Center Arguments: Center squares blend into the general board better. Many players over-search edges expecting others to use edge placement, making center positions paradoxically safer through reverse psychology.

Optimal Strategy: Use a mix. Place 2-3 ships near edges and 2-3 in interior regions. Avoid complete edge clustering AND complete center clustering. Unpredictability beats theoretical optimality.

The One-Square-In Technique

Instead of placing ships directly on edges, position them one square away from borders. This creates protective "padding" that opponents must search through while your ship still benefits from reduced approach directions. This advanced technique works particularly well against probability-based AI.

Corner Utilization

Corners are special positions - attackable from only two directions. However, many opponents check corners specifically because they're memorable locations. Use corners strategically but not predictably. In some games, put a ship in a corner. In others, leave corners completely empty.

Ship-Specific Placement

Carrier (5 squares) - The Vulnerable Giant

Your carrier is statistically the easiest ship to find due to its length. It requires 5 consecutive squares, limiting placement options. Strategic considerations:

Place it first when positioning manually (most constrained)
Consider using it to "anchor" one quadrant while other ships occupy different regions
Avoid obvious horizontal/vertical center placements
Edge placement works reasonably well - the carrier's length makes it easier to fit along borders

Battleship (4 squares) - The Flexible Workhorse

The battleship offers good placement flexibility while maintaining significant size. Use it to balance your fleet distribution:

Place perpendicular to your carrier to vary orientation
Good candidate for "one-square-in" edge technique
Can fit in most board regions comfortably

Cruiser & Submarine (3 squares each) - The Versatile Pair

These medium ships are your most flexible assets. Use them to fill gaps and create optimal spread:

Place in opposite quadrants from each other
One in center region, one near edge works well
Mix orientations between the two
Use to create balanced fleet distribution across the board

Destroyer (2 squares) - The Elusive Target

Your destroyer is statistically the last ship found in most games. Exploit this:

Hide it in the quadrant least occupied by other ships
Consider unconventional positions opponents search last
Corner placement works better for destroyers than larger ships
Can fit in tight spaces between other ships if needed
Some players hide it in dead center (D5-E5 or similar), reasoning opponents search there early then move on

Advanced Techniques

Parity-Based Placement

Against Lieutenant difficulty AI (checkerboard search), you can exploit parity. If you notice the AI searches one checkerboard color systematically, place ships primarily on opposite-parity squares. This delays discovery significantly.

Implementation: Mentally color the board like a checkerboard. Try to position most ship segments on one color, especially smaller ships. When the AI searches the opposite color first, your fleet survives longer.

Probability Countering

Against Commander and Captain difficulties, the AI uses probability mapping that prioritizes center squares. Counter this by favoring less-probable positions:

Edges and corners (lower probability)
Positions near board boundaries
Squares that don't accommodate many different ship placements

The Fortress Strategy

An unconventional approach: cluster ships in one quadrant deliberately. This seems to violate spreading doctrine, but creates a "fortress" effect where that region has high ship density while three quadrants are completely clear.

Strengths: If opponents search the empty quadrants first (likely), your entire fleet survives longer. Once found, the cluster might confuse opponents about which hits belong to which ships.

Weaknesses: Once discovered, enemies can efficiently eliminate your fleet. High risk, high reward. Use occasionally to stay unpredictable.

The Dispersal Extreme

Opposite of fortress: place exactly one ship in each quadrant, with the fifth ship bridging two quadrants along the center line. This forces opponents to search all four regions thoroughly.

This strategy is generally superior against higher-difficulty AI that uses systematic searching. It maximizes the shots required to find your fleet.

Common Placement Mistakes

All-Edge or All-Center

Placing all ships along edges or all in the center creates exploitable patterns. Opponents who recognize your tendency can optimize their search accordingly. Always mix positions.

Diagonal Line Patterns

Some players unconsciously create diagonal patterns across the board. Avoid placing ships such that their positions form recognizable geometric patterns. Randomness beats patterns.

Same Placement Every Game

Humans are creatures of habit. If you find a placement you like, you'll tend to repeat it. Force yourself to vary placements between games, even if it means occasionally using "suboptimal" positions. Unpredictability has value.

Ignoring Adjacency

Placing ships adjacent without strategic reason wastes the opportunity for information separation. If ships must be adjacent due to space constraints, acknowledge this creates vulnerability and adjust other placements accordingly.

Overthinking

Spending 5 minutes optimizing placement only helps marginally. Placement matters, but not so much that it justifies excessive deliberation. Apply these principles quickly and move on to the offensive game where most victories are won.

Adapting to Opponent Difficulty

vs. Ensign (Random)

Placement barely matters. Use this difficulty to experiment with different strategies without consequence. Focus on offensive optimization.

vs. Lieutenant (Checkerboard)

Parity-based placement becomes effective. Try placing ships on one checkerboard color to delay discovery. Spreading still matters but is secondary to parity.

vs. Commander (Probability)

Counter-probability placement: favor edges, corners, and low-probability regions. Spread ships maximally across quadrants. Gaps between ships gain importance.

vs. Captain (Hunt/Target)

Optimal spreading becomes critical. This AI efficiently destroys ships once found, so delaying initial discovery is your main defense. Use all techniques: spreading, gaps, orientation mixing, probability countering.

vs. Admiral (Advanced)

Against Admiral, assume near-perfect opponent analysis. Your placement must be unpredictable rather than theoretically optimal. Vary strategies between games. Accept that even perfect placement only delays inevitable discovery - focus on winning the offensive race.

Practice Exercise

Try this placement experiment across five games:

Game 1: Place all ships along edges
Game 2: Place all ships in center region
Game 3: Use maximum spreading (one ship per quadrant plus one bridging)
Game 4: Cluster all ships in one quadrant
Game 5: Use mixed strategy from this guide

Track how many turns you survive before losing your first ship in each game. The strategy that gives you the most turns is optimal for your typical opponent difficulty level.

Key Takeaways

Mix orientations (horizontal and vertical)
Maintain gaps between ships when possible
Vary placement strategies between games
Adapt to opponent difficulty level
Place destroyer in most unusual location
Don't overthink - apply principles quickly and focus on offense
