Optimize Legal actions in MinMax

Evaluate only better actions.
For example when a player surely loses the trick and he needs to choose between 10, K, D, 9 only the 9 should be evaluated as a legal action.

NULL Evaluation has to be more strict

MM (not ab) is taking too long!

TIMEOUT

A very interesting game: go build; go install; go-skat -minmax2 -minmax3 -html -r 999 -g 8

World generation

Generate 1000 valid worlds
Choose 20 from these
At every move if you find a world is no more valid, make it invalid so that it is not picked up

Analysis of games played

Type of game played
Player
Percentages

e.g.
GRAND/NULL/SUIT/GRAND H/NULL H/SUIT H
You Bob Ana
10% 12% 13% declared
68% 72% 65% won
XX% XX% XX%  lost

INFERENCE

For each suit count the cards played to conclude about the SKAT cards
7 cards of each suit.
1st trick 3 cards
2nd trick 3 cards
High probability that card in the skat (if you don't have it)

REFACTORING

Move players array into SuitState
Maybe also gamePlayers array

Find out why MINMAX Tactics player is losing:

go build; go install; go-skat -auto -n 10  -v  -r 15 -minmax2

BUG in BIDDING HTML

IN HTML if both players have passed the offer to the 3rd is 20 instead of 18

HTML

Change score back at a replay (or do not cound new score)

DONE:

USE MinMax to evaluate declaring after winning the bid

Run a Grand game, and suit game below the bid
Choose game which gives better chances of winning.

Equivalent cards

When player holds two equivalent cards in the hand like 78 or 89 they should always be evaluated together

INFERENCE:

DO not retract everything.!

DISCARD

It is best to discard a doubleton than a singleton and another card.

FLAGS

Allow customization of auto players:
e.g -minmax1 Make 1st player minmax

BUG:

go build; go install; go-skat -n 12 -auto -cpuprofile=mm.prof -minmax2 -minmax3 -v -r 3668
At the 8th game crashes

TACTICS win this game with 106-14, MinMax 67-53!!!!

go build; go install; go-skat -html  -r 1453 -g 22 -minmax2
Opening and wasting the trumps on zero tricks

I will try with MINMAX MC examining all actions in all worlds.

Inference: add beliefs

In a game xskat played 10 trump in a losing trick. He had A trump and J spade kept. 
A belief should be added and retracted if impossible hands occur in distributions.
