#1. Try to stack, be patient.
#2. Never attack with stronger card on top, set as a first card, weakest one which can win (example: 7,A,J,10,9,8 if u attack an enemy stack with 6 on top, cuz its pointless to waste your A(its gonna be K after) and u'll never know what is under that 6).
#3. Find some corner. Its always easier to fight on one front than on many fronts...
#4. If u got a weak stack, waste it and attack enemy stack asap. That makes your enemy weaker and give you space for better cards that you can move from 2nd line. Do it before enemy attack you! If he got stronger stack u gonna lost your stack and land.
#5. Always move your reinforcements to front from first lines to back (like 2nd line goes to 1st line, 3rd to 2nd, etc. till deep corner). Never in opposite way cuz you gonna block army in land which get reinforcement.
Thumb up if u find it useful.
