This is impossible for players which do not cheat.  
You can't give any predictions on the next move of a random player.  
Therefore you have a 1/3 prop. to choose a winning,losing or drawing move.

Here is another 'cheater' (which does not redefine a method):

SYMBOLS = [ :rock,  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;:paper,  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;:scissors ]  
KILLER = { :rock =\> :paper, :paper =\> :scissors, :scissors =\> :rock }

class BHCheatPlayer \< Player

&nbsp;&nbsp;def initialize( opponent )  
&nbsp;&nbsp;&nbsp;&nbsp;super  
&nbsp;&nbsp;&nbsp;&nbsp;@opp = Object.const\_get(opponent).new(self)  
&nbsp;&nbsp;end

&nbsp;&nbsp;def choose  
&nbsp;&nbsp;&nbsp;&nbsp;KILLER[@opp.choose]  
&nbsp;&nbsp;end

&nbsp;&nbsp;def result(you,them,result)  
&nbsp;&nbsp;&nbsp;&nbsp;@opp.result(them,you,result)  
&nbsp;&nbsp;end

end

I have a similar solution:

SYMBOLS = [ :rock,  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;:paper,  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;:scissors ]  
KILLER = { :rock =\> :paper, :paper =\> :scissors, :scissors =\> :rock }  
MAXSIZE = 5

class Symbol  
&nbsp;&nbsp;def +(o)  
&nbsp;&nbsp;&nbsp;&nbsp;return (self.to\_s+o.to\_s).to\_sym  
&nbsp;&nbsp;end  
end

class BHAdaptPlayer4 \< Player

&nbsp;&nbsp;def initialize( opponent )  
&nbsp;&nbsp;&nbsp;&nbsp;@stats = Hash.new()  
&nbsp;&nbsp;&nbsp;&nbsp;@lastmoves = []  
&nbsp;&nbsp;end

&nbsp;&nbsp;def get\_keys  
&nbsp;&nbsp;&nbsp;&nbsp;keys = []  
&nbsp;&nbsp;&nbsp;&nbsp;@lastmoves.each do |pair|  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;keys.unshift( keys.empty? ? pair : (keys[0]+pair))  
&nbsp;&nbsp;&nbsp;&nbsp;end  
&nbsp;&nbsp;&nbsp;&nbsp;keys  
&nbsp;&nbsp;end

&nbsp;&nbsp;def choose  
&nbsp;&nbsp;&nbsp;&nbsp;info = nil  
&nbsp;&nbsp;&nbsp;&nbsp;get\_keys.each do |key|  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;info = @stats[key]  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;break if info  
&nbsp;&nbsp;&nbsp;&nbsp;end  
&nbsp;&nbsp;&nbsp;&nbsp;if ! info  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;SYMBOLS[rand(3)]  
&nbsp;&nbsp;&nbsp;&nbsp;else  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;max = -1  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;msym = nil  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;info.keys.each do |sym|  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;msym,max = sym,info[sym] if(info[sym] \> max)  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;end  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;KILLER[msym]  
&nbsp;&nbsp;&nbsp;&nbsp;end  
&nbsp;&nbsp;end

&nbsp;&nbsp;# called after each choice you make to give feedback  
&nbsp;&nbsp;# you = your choice  
&nbsp;&nbsp;# them = opponent's choice  
&nbsp;&nbsp;# win\_lose\_or\_draw = :win, :lose or :draw, your result  
&nbsp;&nbsp;def result( you, them, win\_lose\_or\_draw )  
&nbsp;&nbsp;&nbsp;&nbsp;get\_keys.each do |key|  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;@stats[key] = create\_stat if ! @stats[key]  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;@stats[key][them] += 1  
&nbsp;&nbsp;&nbsp;&nbsp;end  
&nbsp;&nbsp;&nbsp;&nbsp;@lastmoves.unshift(@lastchoice)  
&nbsp;&nbsp;&nbsp;&nbsp;@lastmoves.pop if @lastmoves.size \> MAXSIZE

&nbsp;&nbsp;&nbsp;&nbsp;@lastchoice = them+you  
&nbsp;&nbsp;end

&nbsp;&nbsp;def create\_stat  
&nbsp;&nbsp;&nbsp;&nbsp;stat = {}  
&nbsp;&nbsp;&nbsp;&nbsp;SYMBOLS.each {|sym| stat[sym] = 0 }  
&nbsp;&nbsp;&nbsp;&nbsp;stat  
&nbsp;&nbsp;end

In the bottom of this mail are my 7 bots.

2 of them ne\_cont\_rand.rb and ne\_cont\_queue.rb uses continuations,  
so its probably best to discard them.

Use .freeze or the method\_added etc. hooks. 🙂

Thanks for the link. Here's a good quote from there:

&nbsp;&nbsp;lypanov notes that the quiz is a bit silly as the reason many good players win in real life  
&nbsp;&nbsp;is because they react fast to the hand formations so unless you have a real person playing  
&nbsp;&nbsp;against a bot guessing the players move by recognition, its kind of boring 😛

Actually, this is one of the reasons I chose to use Paper Rock Scissors. I could have easily picked something with a little more strategy. 😉

This is similar to my solution, but mine does also copy the state of its enemy.

This 'cheater' isn't gauranteed. Try it against this naive random player:

class RandomPlayer \< Player  
&nbsp;&nbsp;&nbsp;def initialize( opponent )  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;super  
&nbsp;&nbsp;&nbsp;end

&nbsp;&nbsp;def choose  
&nbsp;&nbsp;&nbsp;&nbsp;[:paper, :scissors, :rock][rand(3)]  
&nbsp;&nbsp;end

&nbsp;&nbsp;def result(you,them,result)  
&nbsp;&nbsp;end  
end

There's no gaurantee that the answer you get from @opp.choose will be  
the same one the referee gets when he calls choose on the bot. 🙂

Still, it's a mighty clever trick against many strategies.

Still, even in that situation you will pick an attack against a random invalid move which means you'll still have a 50% chance of winning.
